Everything you need to know about maintaining your Sea-Doo, Yamaha WaveRunner, or Kawasaki Jet Ski

You bought your jet ski for the freedom. Those perfect mornings on the water. The rush of carving across your own wake. The weekends that make the work week worth it.

But here's what nobody tells you at the dealership: keeping that machine ready to rip takes more than just hitting the gas and pointing it at the horizon. Between saltwater corrosion, break-in periods, seasonal storage, and the difference between "check every 50 hours" and "check every 100 hours," most riders end up with a maintenance schedule that looks like a college calculus final.

This guide cuts through the confusion. We've pulled the critical information from manufacturer service manuals for Sea-Doo, Yamaha WaveRunner, and Kawasaki Jet Ski models to give you exactly what you need to keep your machine running strong. No unnecessary complexity. No dealer-speak. Just the maintenance knowledge that keeps you riding.

Why Jet Ski Maintenance Is Different

If you've maintained dirt bikes, ATVs, or even boats, jet skis throw you some curveballs. Here's what makes them unique:

The Marine Environment Is Brutal
Saltwater doesn't just touch your machine. It gets inside the cooling system, the exhaust, the pump. Every ride in the ocean is a direct assault on metal components. Fresh water is gentler, but still demands respect.

Everything Happens Faster
That 1500cc engine isn't just sitting there at 3,000 rpm like your truck. It's screaming at 7,000+ rpm, pulling water through the pump at incredible force, and doing it all in an environment where overheating means instant catastrophe.

You Can't Just "Check It Quick"
Your dirt bike? You can pop the seat and check the air filter in 30 seconds. Your jet ski? You're dealing with body panels, sealed compartments, and components designed to keep water out (which also makes them harder to access for maintenance).

Neglect Costs More
Miss an oil change on your truck and you might buy yourself some extra engine wear. Miss a saltwater flush on your jet ski and you could be looking at a seized engine, a destroyed jet pump, or a cooling system that needs complete replacement.

The good news? Once you understand the rhythm of jet ski maintenance, it's actually pretty straightforward. Let's break it down.

The Break-In Period: Your First 5-10 Hours

Every jet ski owner gets excited to uncork that thing and see what it can do. Resist that urge.

Why Break-In Matters
Those first hours of operation determine how your engine will perform for the next decade. The piston rings need to seat properly. The bearings need to establish their wear patterns. The transmission components need to find their groove. Rush this process and you're looking at reduced power, increased oil consumption, and shorter engine life.

Universal Break-In Rules (All Brands)

First 5 Minutes:

  • Idle only or very light throttle

  • Let everything warm up gradually

  • Sea-Doo and Yamaha: 2,000 rpm maximum

  • Kawasaki: Idle speed only

Next 30-90 Minutes:

  • Sea-Doo: Don't exceed 1/2 to 3/4 throttle

  • Yamaha: Stay below 5,000 rpm

  • Kawasaki: Stay below 2,500 rpm for first 5 minutes, then below 4,000 rpm for the next hour

After First Hour:

  • Gradually increase to higher speeds

  • Vary your throttle (don't cruise at constant RPM)

  • Brief full-throttle bursts are actually good (helps rings seat)

  • Continue varied operation for the full break-in period

Total Break-In Duration:

  • Sea-Doo: 5 operating hours (first 3 hours have electronic engine management limiting power)

  • Yamaha: About 90 minutes of varied operation

  • Kawasaki: 10 operating hours minimum

Break-In Service (Critical)

After your break-in period, you need a first service:

Kawasaki (10 hours):

  • Inspect throttle control system

  • Clean air filter drain caps

  • Inspect fuel vent check valve

  • Clean fuel pump screen

  • Inspect throttle shaft spring

Sea-Doo and Yamaha:

  • Most break-in procedures are about operation, not service

  • Jump straight into regular maintenance schedule after break-in

Why This Matters:
During break-in, metal particles from normal wear settle in your oil, your fuel system picks up debris from manufacturing, and components that weren't quite seated properly during assembly find their final positions. This first service clears all that out before it can cause damage.

Regular Maintenance: The Foundation

Here's where most riders get overwhelmed. Between "every ride," "every 25 hours," "every 50 hours," "every 100 hours," and "every year," it feels like you need a spreadsheet just to keep track.

You do. Or you need an app like LookOver that tracks it for you. But first, let's understand what actually needs to happen and why.

Every Ride (Pre-Ride Inspection)

Takes 5 minutes. Prevents hours of frustration.

All Models:

  1. Check engine oil level (dipstick between MIN and MAX marks)

  2. Inspect hull for damage (especially ride plate and water inlet grate)

  3. Clear debris from jet pump intake (weeds, rope, plastic bags)

  4. Verify drain plugs are tight (forgot this once? You won't forget twice)

  5. Check fuel level (running out of gas on the water is embarrassing)

  6. Smell the engine compartment (gasoline vapor means you have a leak)

Yamaha Specific:

  • Check coolant level (between MIN and MAX when cold)

Sea-Doo Specific (RXP-X and GTX):

  • Test iBR (Intelligent Brake and Reverse) operation

Why This Matters:
Five minutes before you launch catches 90% of potential problems. That plastic bag in your intake? It'll overheat your engine in under two minutes of riding. That slow oil leak? It'll leave you stranded halfway across the lake.

After Every Saltwater Ride (Non-Negotiable)

This is the single most important maintenance item for saltwater riders.

The Flush (All Brands):

Sea-Doo and Yamaha have flushing connectors. Kawasaki requires running the engine while flushing. Either way:

  1. Connect fresh water (garden hose to flush port)

  2. Start engine FIRST, then turn on water (Kawasaki: water damage from reverse flow is catastrophic)

  3. Run for 90 seconds to several minutes (Sea-Doo: 90 seconds; Kawasaki: several minutes)

  4. Turn off water FIRST, then stop engine

What You're Flushing:

  • Cooling system passages

  • Exhaust system

  • Any residual saltwater that got into the engine compartment

What Happens If You Skip This:
Saltwater left in your cooling system crystallizes. Those crystals restrict flow. Restricted flow means overheating. Overheating means warped heads, blown gaskets, and a very expensive repair bill. We're talking thousands of dollars to fix what a 90-second flush would have prevented.

Freshwater Riders:
You still need to flush occasionally, especially if riding in dirty or sandy water. But daily flushing isn't as critical as it is for saltwater.

The 50-Hour Service (Or Every Year)

Most riders hit this interval annually. Some hit it monthly.

This is your "standard" maintenance that keeps everything running smoothly.

Engine Oil Change

All Models:
Oil change intervals vary by brand, but the principle is the same.

Kawasaki:

  • Change every 25 hours or yearly (whichever comes first)

  • 4.5L capacity (STX-15F) or 4.5L (Ultra 310)

  • SAE 10W-40, API SG/SH/SJ/SL/SM with JASO MA/MA1/MA2

Yamaha:

  • VX Series: Every 50 hours or yearly (first change at 10 hours)

  • FX SVHO: Every 50 hours or yearly (first change at 10 hours)

  • Capacity varies by model (3.4L to 3.6L)

  • YAMALUBE 4W or equivalent SAE 10W-30/10W-40/20W-40/20W-50

Sea-Doo:

  • Spark: Every 100 hours or yearly

  • RXP-X/GTX: Every 100 hours or yearly (every 200 hours for Rotax 1630 ACE)

  • 2.01L (Spark) or 3L (larger models)

  • XPS 5W40 synthetic blend or equivalent

The Reality Check:
Yes, Sea-Doo says 100 hours. But here's the deal: if you ride in saltwater, dirty water, or push your machine hard, you should change oil more often. Oil is cheap. Engines are not.

Oil Filter:

  • Kawasaki: Every 100 hours (not every oil change)

  • Yamaha: Every oil change (10 hours initial, then with each change)

  • Sea-Doo: Check your model (Spark changes with oil, larger models vary)

Spark Plugs

Check vs. Replace:

Kawasaki:

  • STX-15F: Clean/gap/replace if necessary every 100 hours

  • Ultra 310: Inspect every 25 hours

  • Type: NGK CR9EK (STX-15F), NGK PMR9B (Ultra 310)

  • Gap: 0.7-0.8mm (STX-15F), 0.6-0.7mm (Ultra 310)

Yamaha:

  • VX Series: Inspect every 50 hours

  • FX SVHO: Initial check only (these last a long time)

  • Type: NGK CR9EB (VX), NGK LFR7A (FX SVHO)

  • Gap: 0.7-0.8mm (VX), 0.8-0.9mm (FX SVHO)

Sea-Doo:

  • Replace every 200 hours or 2 years

  • Gap: Not adjustable on most models

  • Type: Model-specific (check manual)

Why Gap Matters:
Too wide and you get misfires. Too narrow and you get weak spark. Either way, you're losing power and efficiency. Check them. Gap them. Replace them when they're worn.

Cooling System Checks

Beyond the saltwater flush, you need to inspect:

  1. Coolant level (Yamaha: check when cold)

  2. Hose condition (cracks, soft spots, leaks)

  3. Clamp tightness (vibration loosens everything over time)

  4. Coolant quality (change every 5 years or 300 hours on Sea-Doo)

Overheating Warning Signs:

  • Temperature gauge climbing

  • Reduced power

  • Unusual noises from engine

  • Steam from engine compartment

Catch these early and you're looking at a hose replacement. Ignore them and you're looking at a new engine.

Jet Pump Maintenance

The Heart of Your Machine

Your jet pump is what makes you move. It's also constantly sucking in water, sand, shells, and anything else floating out there.

Every 50-100 Hours:

Kawasaki:

  • Inspect impeller blades for damage (100 hours)

  • Lubricate/inspect jet pump bearings and seals (25 hours initial, then every 50 hours)

Yamaha:

  • Clean jet intake if clogged (as needed)

  • Inspect thrust nozzle and reverse gate (100 hours on VX models)

Sea-Doo:

  • Visual inspection of impeller and boot (100 hours)

  • Measure impeller/wear ring clearance (100 hours)

  • Replace PTO sleeve and oil seal (200 hours)

Common Jet Pump Problems:

Cavitation (loss of thrust):

  • Usually means damaged impeller or excessive wear ring clearance

  • Makes a distinct "revving" sound without forward movement

  • Needs immediate attention

Vibration:

  • Bent impeller blade (hit something)

  • Damaged pump housing

  • Worn bearings

Why This Matters:
Your jet pump is expensive to replace. But individual components (wear rings, seals, bearings) are relatively cheap if you catch wear early. Ignore the vibration and you'll destroy the whole assembly.

Battery Maintenance

All Models: Inspect every 50-100 hours

  1. Check terminals (clean, tight, no corrosion)

  2. Test charging system (should show 14V when running)

  3. Look for physical damage (cracks, swelling, leaks)

Sea-Doo Note:
Maintenance-free batteries. No electrolyte to check. But still inspect condition and connections.

Kawasaki:
18 Ah, 12V system

Yamaha:
19 Ah, 12V system

Storage Tip:
Remove battery during off-season. Store in cool, dry place. Charge monthly during storage. Dead batteries don't recover well.

The 100-Hour Service (The Big One)

This is your annual comprehensive inspection for most riders.

What Gets Added (Beyond 50-Hour Items):

All Brands:

  1. Air filter inspection/cleaning

    • Clogged filter = reduced power and fuel economy

    • Sea-Doo Spark: No cleanable filter, replace if dirty

    • Others: Clean and inspect for damage

  2. Fuel system inspection

    • Check all fuel lines and connections for cracks

    • Inspect fuel cap O-rings

    • Sea-Doo: Inspect water separator

  3. Steering system

    • Cable condition and lubrication

    • Check for free movement

    • No binding or excessive play

  4. Throttle cable inspection

    • Lubricate fittings

    • Check for smooth operation

    • Adjust free play if necessary

  5. Engine mounts and bolts

    • Vibration loosens everything over time

    • Tighten to specification

    • Replace if rubber is deteriorating

Kawasaki Specific:

  • Inspect valve clearance (100 hours) - Professional service recommended

  • Inspect coupling damper

  • Inspect impeller blades (remove for thorough inspection)

  • Check steering/shift cable ball joints

Yamaha Specific:

  • VX Series: Inspect cooling water hoses (Professional)

  • FX SVHO: Lubricate intermediate housing, throttle body valves (Professional)

  • Replace oil filter (100 hours on VX, others vary)

Sea-Doo Specific:

  • Inspect iBR components (on equipped models)

  • Check sacrificial anodes (replace when 50% eroded)

  • Inspect body panels and hardware torque

  • Check fish finder transducer support (if equipped)

Why 100 Hours Matters

This is your "nothing gets missed" service. All the things that slowly degrade over time get inspected, adjusted, or replaced. Skip this and you're rolling the dice on your next season.

Seasonal Maintenance: Storage and Startup

For riders in freeze zones or those who store their ski for extended periods.

Preparing for Storage (Fall)

The Right Way:

1. Fuel System

  • Fill the tank completely (prevents condensation)

  • Add fuel stabilizer (prevents fuel degradation)

  • Kawasaki: Run engine for several minutes to circulate stabilized fuel

  • Sea-Doo/Yamaha: Similar procedure

Why Full Tank:
Empty space in your tank = air. Air contains moisture. Moisture condenses as temperature changes. Water in your fuel system = corrosion, gummed-up injectors, and potential engine damage.

2. Oil Change

Change oil BEFORE storage, not after. Here's why:

  • Used oil contains acids, moisture, and contaminants

  • Letting those sit in your engine all winter = internal corrosion

  • Fresh oil provides protection during storage

3. Cooling System

Flush thoroughly:

  • Run fresh water through entire system

  • Drain as completely as possible

  • Add antifreeze if storing in freezing temperatures

Critical for PWCs:
Water trapped in the cooling system can freeze and crack engine components. One hard freeze and you're looking at thousands in damage.

4. Exhaust System

  • Sea-Doo: Spray spark plugs with fogging oil

  • Kawasaki: Turn engine over several times after fogging to coat cylinders

  • All brands: Drain any water from exhaust

5. Battery

  • Remove completely

  • Clean terminals with baking soda solution

  • Apply dielectric grease

  • Store in cool, dry place (not freezing)

  • Charge monthly during storage

6. Exterior

  • Wash thoroughly (remove salt, dirt, grime)

  • Dry completely

  • Apply wax or protectant to hull

  • Lubricate all metallic components (especially after saltwater use)

Sea-Doo Specific:

  • Remove seat to prevent condensation

  • Clean bilge with hot water and detergent

  • Lift front end to drain completely

7. Where to Store

  • Dry, ventilated location

  • Cover to protect from dust (but allow air circulation)

  • Block ventilation holes to prevent pests

  • Slight nose-up angle helps drainage

Spring Startup (The Right Way)

Don't just fire it up and go. Here's the proper sequence:

1. Pre-Start Inspection

  • Reinstall battery (connect RED positive first, then BLACK negative)

  • Check all fluid levels (oil, coolant)

  • Inspect fuel condition (smell it, if it smells stale, drain it)

  • Remove any winter covers or plugs

2. External Checks

  • Walk around inspection (hull damage, loose panels)

  • Check steering operation

  • Verify drain plugs are installed

  • Clear any debris from intake

3. First Start

  • First start of season should be brief (under 30 seconds)

  • Listen for unusual noises

  • Watch for warning lights or alarms

  • Verify cooling water discharge (Yamaha has pilot outlet to observe)

4. Pre-Launch Service

Perform all items from your regular maintenance schedule that came due during storage:

  • Change oil if you didn't do it in fall

  • Check/change spark plugs

  • Inspect all hoses and connections

  • Lubricate cables and pivot points

5. First Ride

  • Take it easy first ride of season

  • Don't push to full throttle immediately

  • Let everything warm up gradually

  • Watch temperature gauges

  • Listen for any unusual sounds

Common Spring Problems:

Won't Start:

  • Check battery charge

  • Verify kill switch lanyard is attached

  • Check fuel condition

  • Look for loose connections that loosened over winter

Runs Rough:

  • Old fuel (drain and replace)

  • Fouled spark plugs (clean or replace)

  • Water in fuel system (needs professional service)

Overheating:

  • Cooling system not fully flushed of antifreeze

  • Blockage in cooling passages from storage debris

  • Failed water pump

Saltwater vs. Freshwater: Different Rules

Saltwater Riders Face Unique Challenges

The Corrosion Factor

Saltwater doesn't just cause surface rust. It:

  • Crystallizes in cooling passages

  • Attacks aluminum components

  • Corrodes electrical connections

  • Degrades seals and gaskets faster

  • Leaves deposits that restrict flow

The A+ Maintenance Schedule (Sea-Doo):

If you ride in salt or dirty water, Sea-Doo recommends an "A+" schedule:

After EVERY Ride:

  • Flush engine compartment

  • Flush exhaust system

  • Rinse exterior thoroughly

Monthly:

  • Lubricate all metallic components

  • Inspect sacrificial anodes

  • Check electrical connections for corrosion

  • Apply anti-corrosive spray

More Frequent Service Intervals:

  • Oil changes: Consider 50% reduction in intervals

  • Cooling system inspection: Monthly instead of every 100 hours

  • Impeller/pump inspection: More frequent checks for wear

Sacrificial Anodes

Sea-Doo models (and some Yamaha/Kawasaki) have sacrificial anodes:

  • Purpose: These corrode instead of your engine components

  • Location: Typically near cooling system or pump housing

  • Inspection: Check every 100 hours (monthly in saltwater)

  • Replacement: When 50% eroded

Why This Matters:
Anodes cost $20-30. Engine components cost thousands. Let the anode do its job.

Electrical Connections

Saltwater loves to destroy electrical connections:

Prevention:

  • Apply dielectric grease to all connections

  • Inspect monthly for green corrosion

  • Clean with electrical contact cleaner

  • Replace corroded connectors immediately

Warning Signs:

  • Intermittent electrical issues

  • Dash warnings that come and go

  • Starting problems that seem random

Often these are corrosion-related, not actual component failure.

Freshwater Riders

You're Not Off the Hook Entirely:

While less aggressive than saltwater:

  1. Still flush after dirty water

    • Mud and silt can clog cooling passages

    • Sand acts like sandpaper on pump components

  2. Watch for algae growth

    • Can clog cooling system

    • Restricts water flow = overheating

  3. Zebra mussels and invasive species

    • Clean hull before moving between water bodies

    • Some states require inspection

    • Prevents spreading invasive species

  4. Follow standard intervals

    • You won't need the "A+" schedule

    • But don't skip regular maintenance

Brand-Specific Quirks and Notes

Common Problems and How to Avoid Them

The Top 5 Jet Ski Killers

1. Skipped Saltwater Flushes

The Problem:
Saltwater crystallizes in cooling passages. Restricted flow = overheating = catastrophic engine damage.

The Cost:
$3,000-8,000 for engine repair/replacement

The Prevention:
90 seconds of flushing after every saltwater ride. Set a phone reminder if you have to.

2. Running Out of Water

The Problem:
Jet skis are water-cooled. No water = no cooling. Run it for more than 15-30 seconds without water and you risk serious damage.

Common Scenarios:

  • Testing throttle on trailer

  • Flushing with water off

  • Beaching in shallow water where pump can't pull water

The Prevention:

  • Never run engine on trailer without flush attachment

  • Always start engine AFTER water is flowing (Kawasaki especially critical)

  • Avoid running in less than 3 feet of water

3. Sucking Up Debris

The Problem:
Rope, plastic bags, weeds, or other debris gets sucked into pump. Best case: loss of thrust. Worst case: damaged impeller, seized pump, overheating from blocked cooling intake.

The Prevention:

  • Pre-ride inspection of intake grate

  • Avoid areas with floating debris

  • Learn to stop engine immediately if you feel loss of thrust

The Fix:

  • Stop immediately

  • Remove from water if possible

  • Clear debris from intake

  • Inspect impeller for damage before restarting

4. Ignored Warning Signs

The Problem:
Small issues become big problems when ignored.

Warning Signs:

  • Temperature gauge climbing

  • Loss of power

  • Unusual vibrations

  • Strange noises

  • Warning lights or alarms

The Prevention:

  • Stop immediately when you notice any of these

  • Don't "just make it back to the dock"

  • Investigate before continuing

The Cost:

  • Catching overheating early: $0-200 (thermostat, hose)

  • Ignoring it: $3,000-8,000 (warped head, cracked block)

5. Improper Storage

The Problem:
Water left in system over winter freezes and cracks components. Old fuel gums up injectors. Corroded electrical connections. Rodent damage.

The Prevention:

  • Complete winterization procedure

  • Store in dry, ventilated location

  • Remove battery

  • Use fuel stabilizer

  • Block ventilation holes against pests

  • Consider skill level honestly

  • Remember: screwing up valve clearance is expensive

Tracking It All: Why a System Matters

Here's the brutal truth: maintaining a jet ski properly requires tracking dozens of different intervals, conditions, and procedures.

The Manual Tracking Problem:

You need to remember:

  • Hours since last oil change

  • Hours since last spark plug check

  • Date of last saltwater flush

  • When you last inspected the impeller

  • Whether you're on the 25-hour or 50-hour interval

  • If you hit the 100-hour "big service"

  • What service manual says for your specific model

  • Seasonal storage dates

  • Battery removal/charging schedule

For Multiple Machines:
Got a Sea-Doo and a Yamaha? Now you're tracking two completely different service schedules. Three machines? Good luck keeping it straight.

The Forgotten Service Problem:

What happens when you can't remember if you changed the oil at 45 hours or 65 hours?

  • Do it too soon = wasted money

  • Do it too late = engine wear

The Solution:

This is exactly why we built LookOver. Track every machine, every service, every reminder in one place:

  • Set reminders by hours, date, or mileage

  • Get notifications when service is due

  • Log services with photos of receipts

  • Never guess whether you're current on maintenance

  • Separate saltwater and freshwater usage

  • Track model-specific intervals automatically

Offline-First Design:
Because we know you're not always at the dock with cell service when you need to check your maintenance log.

Your Seasonal Rhythm

Spring (Pre-Season):

  • Remove from storage

  • Battery reinstall and charge check

  • Fluid level inspection

  • First start (brief, just to verify)

  • Pre-launch comprehensive inspection

  • Test ride (easy pace, verify everything works)

Summer (Riding Season):

  • Pre-ride inspection before every ride

  • Saltwater flush after every saltwater ride

  • Track hours toward service intervals

  • Watch for warning signs during operation

  • Post-ride exterior rinse

Fall (Pre-Storage):

  • Final maintenance service

  • Oil change

  • Fuel stabilizer addition

  • Cooling system flush

  • Battery removal

  • Exterior cleaning and protection

  • Prepare for storage

Winter (Storage):

  • Monthly battery charging

  • Occasional inspection for rodent damage

  • Ventilation check

  • Dream about next season

The Bottom Line

Jet ski maintenance isn't complicated. It's just consistent.

Flush after saltwater. Change your oil on schedule. Check the obvious stuff before every ride. Do the 100-hour service when you're supposed to. Store it properly in the off-season.

Do these things and your machine will start every time, run strong, and last for decades. Skip them and you'll be shopping for a new engine before you've finished paying off the current one.

The choice is pretty simple.

Want to stop guessing and start tracking? That's what LookOver is for. Built by riders who got tired of scrolling through mile-long notes app entries trying to figure out when they last changed the oil. One app for every machine you own. Purpose built for powersports.

Because the goal isn't to become a master mechanic. The goal is to spend less time wrenching and more time riding.
