Maintenance and Mechanical
Routine engine service, done where the boat is.
Most engine maintenance doesn't need a shop. Oil and filter changes, gear lube, impellers, fuel filters, plugs, and batteries can often be handled at your dock, driveway, or storage lot.
Availability depends on the vessel, engine, scope, and working conditions, so we ask for your engine make, horsepower, model, and year up front. If something needs a shop or a specialist, we'll say so rather than guess.

Tell us about the engine
Engine make, horsepower, model, and year let us confirm whether we can do the work and what parts to bring. The estimate form asks for these when you select a mechanical service.

MarineMobile does not claim to be an authorized dealer or warranty service provider for any engine brand. If your engine is under warranty, check with your dealer first about how outside service may affect coverage.
What can be done on-site
Service depends on the vessel, engine, scope, access, and working conditions. Some jobs are better suited to a shop, and we'll tell you when that's the case.
Routine labor is $125/hr, with a $125 standalone service minimum. Parts, fluids, supplies, and travel are quoted before approval.
Common questions
Can you replace an impeller or change engine oil at my dock?
Often, yes. Oil changes and impeller service can usually be done at a dock, driveway, or storage lot, depending on the engine and how accessible it is. Send us the engine details and we'll confirm.
Do you service my engine brand?
We work on many outboard, sterndrive, inboard, and PWC engines. Send the make, horsepower, model, and year and we'll let you know. We don't claim manufacturer authorization.
