"Hello,
I have a 1993 T9.9 EXHR in which I replaced the original water pump impeller with a "Sierra" OEM equivalent. Prior to the replacement, water would always come out the pee hole on startup. Now only drips comes out until, running it for a minute or so, shutting off, letting set for a minute and restarting, it then begins to pee and operates fine. I assume the thermostat is opening allowing flow. I've motored for 15 minutes like this at 1/3 throttle with no problems. My question, is there a PRV on the cooling system on this engine and if so, where is it (Seloc manual is vague)? I have double checked the impeller installation and know it is correct, as witnessed by the fact it pumps fine once the engine is warm. I have no reason to suspect an unusual blockage, as this motor is used summers only in a clean fresh water lake and have never had prior problems. The old impeller was not that bad of shape (intact). Any thoughts or suggestions would be greatly appreciated.
Thanks"
