Impeller and housing changed. Old impeller was definitely on its way out. Temp seems to be good at the thermostat housing. Having never had the IR gun I also checked the exhaust risers and saw that the starboard riser was up to ~177 after running and cooled down to ~150 at idle. The port...

Good point. Brain failure. I'm thinking of things that have the impeller in the drive.

Freshwater lake. It does spend most of its days on the trailer though. We actually hadn't been able to use it for a couple years prior to this summer. Has been out maybe a half dozen times this year with no issue. Haven't had the opportunity to run that hard for that long though. Going to...

And so it shall be done. I see kits with just the impeller and others that include the housing. Given this one may be far too many years old should I go ahead and get the housing as well? Presumably I should stick with the OEM Mercruiser/Quicksliver parts or are the aftermarket parts capable...

Local freshwater lake. Boat spends most of its time on the trailer. Not too much gunk in the lake.

I have seen the seawater impeller/pump mentioned frequently. I can't say when it was replaced last. Would it just decide it had enough after an extended high load like that or cause the large temp fluctuations after we came back down to idle? I believe I have located the pump and can access...
