Yamaha Cooling

[swantzilla]

I have a C115 and a F250. The C115 has a strong "pee stream' while the F250 has a weak stream. (no prostate jokes please) The C115 is a '95 and the F250 is new. Should the F250 have the same stream as the C115? Should the F250 go back to the dealer?

Re: Yamaha Cooling

Shaft length has alot to do with it,but what I'd recommend is getting water pressure gauges for both engines so you know how far you can trim engines and you will have reference pressures to go by so you will know when water pumps will need replacing.

Re: Yamaha Cooling

its ok, the F motors only produce half the heat and the pressurecontrol valving is different. the first F225 I ever mounted scared me the tell tale was so weak.
