Servicing Your Outboard

Every 100 Hours / 12 Months - Whichever comes first, your outboard could need a service. This will ensure you have no problems when out on the water. If you have a new Yamaha Outboard under warranty, it's advised to keep up with the annual services to validate your warranty for years to come.


Each outboard has it’s own special service requirements dependant on the number of hours. We follow the manufacturer's maintenance interval chart in accordance with your current engine hours. This ensures that your outboard is serviced properly, which reduces the chances of having problems in the future.

How It Works

To start, we will ask for your outboards model and serial number to ensure that we can quote for an accurate service using genuine parts and oils.

We come to you - this makes servicing your engine quick, clean and hassle free. Our van is fitted with the equipment and parts needed to carry out servicing and repairs. We don't charge a 'call-out', but there is a minimum charge for the first hour depending on your location. Please ask / get in touch for more information. 


We can service your outboard where you desire, at a marina* or at your home on the trailer. With smaller outboards, if you prefer; we can pick up, service and return at your convenience too. We use oil draining tools, eliminating oil spills thereby keeping your outboard, boat and area clean.
