I have a 92 Yamaha 225 outboard, 300 hours on the motor. Bought it
with 275 hours on it. I have had it for about a 1.5 years and notice
now the water isnt ****ing out the hole as it once did. I ran
monofiliment in there but still doesnt flow like it use to.
Additionally, when I run it on the hose now it will give me a warning
after a few minutes which appears to be heat related.
If I am running in the river etc. I havent had any heat warnings but
I am wondering if it is just a matter of time.

Should I be considering the thermostats first then the water pump?

Does anyone have any feedback?

Thanks,
Keith

If you haven't changed the water pump impeller since you've owned it -
Its time. The Tell-tale flow is independent of the Themostat position.
Poor flow means the pump isn't pumping as much or you have an
obstruction. Opinions here vary but most folks say you should change
your impeller every 1 2, or 3 years. While you're in there you can
check for damage to the housing, bad gaskets, obstructions, etc.

Not only should the water pump and thermostats be replaced, due to the
motor's age and use, but remove the pressure relief valve, spring, and
rubber grommet and inspect for sticking, debris, or dislodging. It is the
oval housing fastened to the lower stb. side of the exhaust cover and
connected to about a 1" hose. Another thing to remember is that Yamaha V4
and V6 motors overheat easily on a flusher. It is best to use a dual feed
flusher or the rectangular muffs that Yammy sells.
