I have a 1997 Yamaha 130 hp 2cycle engine that I bought used. They have a flush/run hose on the engine. Someone told me that is only for flushing and not for running. Is this true? Thanks for a answer. Whalers are the best boats ever made !

Yes that is correct. The motor uses more water than that hose connection can supply. For running the motor purchase one of those lower unit earmuffs usually 7 to 12 dollars.

The water pump impeller needs water for lubrication. The flushing adapter does not wet the water pump and so you would do damage to your water pump if you were to run the motor hooked up to the flushing adapter because the pump impeller would be rotating in a dry state.

Depends! My manual states that you can run the engine on the flush port if engine is in the down position(on a trailer). If it is tilted at the slip then do NOT run it. Personally I se no need to run with hose attached. All you are doing is flushing it so if water pressure is there, why run it?

Thanks for the replys. They make sense. I will run it in the yard with muffs to make sure no damage to the pump. Thanks again.
