Not happy. Now what's the next thing?

Yes it's the two bolts per housing,two on the left housing and two on the right housing that hold the thermostats . The right bolt on the left housing the treads ( not on the bolt ,the treads that the bolt screw into ) are stripped. But they don't have lock washers,never did . I did it, I didn't know that the housing has one side of it is thicker that the other side so when I installed the bolt it wouldn't go all the way in and I put to much pressure on the bolt. Stripping it. When I removed the housing to clean them out I must have put the left one in backwards. The only good thing is that I did it, a lesson learned. I'm tired of learning my lessons , I just want to fish. It's a 1/2 inch bolt

And btw, when you do the water pump, pop that lower housing out and check the gasket under it, had that kick my but on my 150 merc

Spare, your talking about the base? I changed that 2 years ago cause I was getting water mixed with the lower unit oil and that fixed the problem. It wasn't to bad just had to lift it out it was tough but we got it.
