What We Service

Fresh Oil For Every Engine

We change engine oil and filters on gas and diesel inboards, sterndrives, and Yamaha jet engines.

Marine engines work hard at steady loads, and old oil loses its ability to protect bearings and cylinders. Changing oil and filters on schedule, and before winter storage, keeps the engine protected and running cleanly.

Our Oil Change Process

Four steps that keep your engine protected all season.

  1. Request

  2. Schedule

    We set a time at the marina, often alongside other service.

    Old oil comes out, a new filter goes on, and fresh oil goes in.

Frequently Asked Questions

Oil Change Questions

Spring oil service is $145 plus oil and filter. Fall oil service with winterization is $161 per gas or diesel engine plus materials. On a new Yamaha jet boat or WaveRunner, the 10 hour service at $250 per engine includes the oil change.

Follow the hour interval in your owner manual, and change the oil before winter storage so used oil does not sit in the engine all winter.

Milky oil usually means water is getting into the engine, which should be checked before you run it again.
