Your boat runs on hours - track every service from launch to haul-out

Boats don't have odometers. Engine hours are the only measure of wear, and they drive every service interval. Oil changes, impeller replacement, lower unit service, spark plugs, fuel filters. All hour-based. All easy to lose track of when you're focused on time on the water.

Most marine engines need an oil change every 100 hours or annually. Impellers should be replaced every 200-300 hours or every two years. Lower unit gear oil needs attention every 100 hours or annually. LookOver tracks all of it by hours and dates, with compound reminders that trigger on whichever comes first.

If you're in a climate where the water freezes, winterization is the single most important maintenance event of the year. Flush the cooling system. Fog the engine. Change the lower unit oil (water intrusion shows up here). Stabilize the fuel. Disconnect the battery. Treat all metal surfaces.

LookOver lets you build a winterization checklist once and reuse it every fall. Log each step as you go. Add photos of the lower unit oil (milky oil means water intrusion and an immediate problem to address). When spring commissioning rolls around, you know exactly what was done and what to inspect.

Saltwater boating compresses every maintenance interval. Post-outing flushing is mandatory. Corrosion checks become weekly tasks during the season. Zinc anodes need regular inspection and replacement. Hardware corrodes faster. Electrical connections degrade.

LookOver handles the more aggressive schedule with custom intervals. Set your flush reminder for after every outing. Set zinc anode checks at monthly intervals. Track corrosion-related maintenance separately from routine engine service so you can see the true cost of saltwater boating over time.

Your maintenance schedule depends on your propulsion type. Outboards need lower unit service and impeller replacement. Inboards need raw water pump service, transmission fluid, and exhaust system checks. Sterndrives combine elements of both.

LookOver doesn't force you into a preset template. Set up the services that match your specific engine and drive type. Whether you're running a Mercury four-stroke outboard or a Volvo Penta sterndrive, the intervals are yours to define.

Most trailered boats need trailer maintenance tracked alongside the boat itself. Wheel bearings, brake service, tire condition, winch strap inspection, and lighting. LookOver lets you add the trailer as a separate machine in your garage, with its own maintenance schedule and service history. Both the boat and trailer tracked in one app, ready for every launch.

Documented maintenance history matters when selling a boat. Marine surveys assess condition, but a complete service log demonstrates consistent care. LookOver's PDF export provides a professional record of every oil change, every impeller swap, every winterization, ready to hand to a surveyor or buyer.
