Chris,
It might also be the thermostats or some old salt crystals gunking up the cooling passages. It's pretty easy to look at an impellar and tell if it's been recently replaced as opposed to last season's worn impellar, so if the guy is good it just might be OK. That said though, I would have made a new water pump impellar and housing part of the job price and just done it. Learned long ago not to let silly little things like muck up the job. Once worked for a guy that really drove that lesson home, he would stop me and tell me "the customer's not going to pay for that" every time I'd go to do one those little things, and guess what? Yup, came back and bit us in the backside every time
Got a few stories from that job :eek1:

I think im going to replace both thermostats. The guy was very religious on flushing the motor everytime he went out so he says anyway. The motor is so clean i dont doubt anything he said. The motor was sitting in his garage for a few years so im thinking the thermostats makes the most sense. Upon looking in the parts book there 143 degree thermostats so thats about where it should be running at

Not on an outboard. Outboards need the thermostats to govern pressure from the water pump. Without them the water doesnt circulate correctly resulting in a hotter running motor.
Outboards are in the own category. Take alot of what you and i know about car motors and toss it out the window!

Chris, I do have an I/O on this boat but my last boat was a 140 horse Evenrude outboard which I did two engine jobs on in 18 years. I had to replace the pistons twice. I could take one of those apart with my eyes closed.
There's not much to them.
My engine I have now is a 350 Volvo Penta made by Chevy. I also had to do an engine job on this one too. Now it runs like a dream (so far)

I'd be concerned about why the thermostats where missing. Most people put in new ones after pulling out the old ones. I'd guess that motor had an overheating problem that new thermostats didn't solve and someone got smart thinking leaving them out would solve the problem.

Chris I threw out the thermostats on the Evinrude and it always ran cool.
Once the piston head came off. It exploded right through the side of the engine pushing the starter off. I had a pliers and screwdriver and my wife asked if I could fix it so we could get back. It was a factory defect and Evinrude paid for half the parts because it was recalled but the original owner never returned it for service. The second time the connecting rod broke spewing roller bearings all through the powerhead. I managed to hone it down enough to save the head.

Ok theres a shortage on LI of Merc thermostats. Ended up trucking to Island Park to get them. Anyplace around here didnt have any in stock.
Paul ouchie Ive never been a fan of evinrudes. Ive always prefered merc. They tend to last longer. Evinrudes are notorious (atleast the older ones) for losing a cylinder.
Ive decided i like spending my friends money LOL
