Common questions
Is it worth repairing an older outboard?
Usually yes. Most outboards last decades with regular service. We tell you when an engine is worth fixing and when it is honestly time to replace it.
Do you stock outboard parts?
We stock common Tohatsu service parts and frequently used parts for Mercury, Yamaha, Honda and Suzuki. Anything else, we source quickly.
My outboard overheated. How fast can you look at it?
Overheats jump the queue. In the May–August window we aim for a 48-hour diagnostic on heat issues. Call the shop instead of using the form when it's urgent.
