Will using an independent service provider void my Honda Marine warranty?
No. Under the federal Magnuson-Moss Warranty Act (15 U.S.C. 2302), a manufacturer can't void your warranty just because an independent provider did the maintenance or repairs. You have the legal right to choose where your boat is serviced. We document the date, engine hours, and every OEM part and fluid we install, so your records satisfy the warranty.
What oils and fluids do you use?
We use genuine Honda Marine oils matched to your engine family: Honda Marine 10W-30 four-stroke oil, and Honda Marine Hypoid Gear Oil in the gearcase.
Why do triple and quad setups have a different labor rate?
Multi-engine rigs need extra calibration: computer alignment of Intelligent Shift & Throttle (iST) systems, and an on-water sea trial. Motor wells are also tight to work in. So triple and quad setups are billed at $250 per hour.
Does my Honda iST system need calibration at an annual service?
Yes. At every 100-hour and annual service we scan the engine with Honda diagnostics, check for stored fault codes, verify iST throttle and shift response, and reset the service hour counter.
Do you charge a travel or convenience fee?
No. Our flat rates include coming to you anywhere in our standard service area. We never add a convenience surcharge.
How do you handle old, corroded or seized hardware?
Our flat rates assume normal, serviceable condition. If we find structural corrosion, seized fasteners or broken bolts, we stop and send you time-stamped video by text and email. Extraction or thread repair is $250 per hour plus parts, and only with your written approval.
How often does my Honda outboard need service?
Honda Marine calls for routine service every 100 hours or once a year, whichever comes first. New engines also need a 20-hour break-in service.
