Again, the engine must run, with prop removed, for about five minutes. Midsize engines (25 to 50 hp): Use only the factory 'WASH' port located in the lower port/left side of the gear case. The prop must be removed and the engine run for about five minutes with either procedure. Smaller engines (2 to 20 hp): Flushing in a small container (such as a flushing bag, small bucket, or can) is acceptable.įor engines 5 hp and up, an optional flushing attachment (Honda part #06190-ZV1-860) is available that allows flushing the engine through a port on the side of the gear case. In all cases, the engine must be in the vertical position during flushing and after, to drain the water from the engine. Honda's flushing procedure varies by engine size and model.

The engine should be kept in neutral and not run above a fast idle speed (1,000 rpm maximum).

Watch the engine's 'tell-tale' overboard water indicator to ensure that the engine is pumping water.

Be vigilant, and don't leave the engine while flushing.

When attaching the muffs, be sure they cover the water inlets completely and don't pop or slide off when the water is turned on.

These can be purchased from aftermarket shops.

If your engine doesn't have water intakes on the sides of the gear case, you will need a special type of flushing attachment that covers the front of the gear case.

If your engine has additional water intakes that are not being directly fed water via the flushing muffs, they must be sealed off with a bit of duct tape, or overheating may occur.

That's it, with the following precautions: Connect to a garden hose, fit the muffs over the engine's water intakes on the sides of the gear case, turn the water on, start the engine, and let it run.
