Do you service Yamaha outboards on O‘ahu?
Yes. We service Yamaha outboards at your boat anywhere on Oʻahu, with no travel fee: yearly and 100-hour service, diagnostics and repairs. From F2.5 kickers to the V8 F350, plus older Yamaha two-strokes and HPDI engines.
Can you read Yamaha fault codes?
Yes. On Yamaha engines that support it we connect the Yamaha Diagnostic System (YDS) to read fault codes, engine hours, hours by RPM and alarm history, and to test sensors.
How often should a Yamaha outboard be serviced in Hawai‘i?
At least once a year. We do a full yearly service every 200 hours or 1 year, whichever comes first, with a new water pump impeller every time, plus the 100-hour service Yamaha calls for if you run a lot of hours. Each model's factory schedule is in our Yamaha service guides below.
Do you use genuine Yamaha parts?
We use OEM (factory) parts or parts of equal quality unless you ask otherwise. Parts usually take about a week to reach Hawaiʻi, so we book the visit when they arrive.
