What is included in a 100-hour service for my boat engine?

A 100-hour service includes oil and filter changes, fuel filter replacement, spark plug inspection or replacement, cooling system check, and inspection of belts, hoses, and electrical connections. We also test the engine’s performance to ensure reliability and safety.

Why is annual engine maintenance important?

Annual maintenance prevents unexpected failures, keeps your engine running efficiently, and prolongs its life. Regular checks catch minor issues before they become costly repairs, ensuring safe and smooth operation on the water.

Do you perform inspections on all engine components?

Yes, we inspect the entire engine, including fuel, cooling, lubrication, and electrical systems. We check for wear, corrosion, or leaks and provide recommendations for any parts that need replacement or adjustment.

How often should I schedule a 100-hour service?

A 100-hour service is recommended every 100 operating hours or at least once a year, whichever comes first. Boats in heavy-duty or saltwater use may require more frequent servicing.

Do you provide a maintenance report after the service?

Absolutely. After service, we provide a detailed report documenting all inspections, replacements, and recommendations. This helps track engine health and ensures warranty compliance.

Can regular maintenance improve engine performance?

Yes, routine maintenance ensures your engine runs smoothly, operates efficiently, and delivers maximum power. Preventive care also reduces the risk of breakdowns and extends the life of your engine.

Drain

We extract old fluids while the engine is warm to ensure all contaminants are removed from the sump.

Common Questions

Do I really need this every year?

Yes. Even if you don't hit 100 hours, engine oil degrades over time and collects moisture. Saltwater impellers can take a "set" and become brittle if left sitting.

Will this void my warranty?

No. We use OEM parts and fluids that meet or exceed factory specifications. We provide detailed receipts to prove maintenance compliance.

Planning Your Annual Boat Engine Maintenance

Boat engine maintenance is easiest to keep on track with a simple rule: every 100 hours or once a year, whichever comes first. Even an engine that barely ran this season benefits, because oil collects moisture over time and a saltwater impeller can take a set and turn brittle while it sits.

When you book, have your engine make, model and current hours handy, and mention anything unusual from last season, such as overheating alarms, water in the gear lube or hard starting. We scan for stored fault codes before we begin, replace oil, filters, impellers and zinc anodes, and run the engine to verify oil pressure, cooling temperature and leaks before signing off. You receive detailed receipts for your maintenance records.

Oil Change or Full 100-Hour Service?

Many owners start by looking for a mobile boat oil change. Fresh oil and new filters are a core part of this service, but oil alone leaves other wear items unchecked. The same visit also covers the fuel separators, water pump impeller, zinc anodes and lower unit gear lube or transmission fluid, followed by a test run for oil pressure, cooling temperature and leaks.
