Service

Service notes.

What our service work and the manufacturer documentation say about keeping this model running.

Service notes

Check cooling-water discharge, intake condition and the water-pump service history, and inspect the gearcase for oil leakage or impact damage. Inspect spark plugs, ignition components, fuel filters, hoses and connections for deterioration or contamination. Check propeller, propeller shaft, anodes, skeg, trim and tilt system and steering connections for damage and secure attachment. Inspect the engine mounting and transom for movement, cracking or corrosion. Verify alarms, emergency stop lanyard or equivalent shutdown device, neutral-start interlock and control operation where fitted. For cylinder dimensions, rotational speed, pressures, clearances, temperatures, wear limits and setting values, refer to the manufacturer documentation for the exact figure.

Need this part?

Request a quote for this model.

Free of charge — we forward your request to qualified suppliers for American Honda Motor equipment from our network of over 114,000 maritime companies.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we usually come back with prices; without them we have to ask first, which costs a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — send it as a reply to our confirmation e-mail.
