FAQ

Outboard engines are safety-critical equipment. Proper servicing reduces the risk of breakdowns, improves fuel efficiency, and ensures your engine performs when you need it most — especially offshore. We never cut corners where safety is concerned.

How often should my outboard be serviced?

Most manufacturers recommend servicing your outboard every 12 months, or 100 hours, whichever comes first out of the two.

Do you use genuine parts?

As an authorised service centre for Suzuki Mercury and Tohatsu, we always use genuine OEM parts to ensure high quality components are used to protect your outboard and keep it running efficiently.

Can you service older engines?

Yes – we regularly work on older engines, while parts may not be as common, we are committed to keeping these older generation outboards on the water to outrun the rest!

Do you provide service records?

Yes – we always state the outboard condition and service notes on every service invoice and upload the service record to the appropriate dealer portal for other dealers to see if required and keeps the record in case of warranty dispute.
