Chris, the impeller I started with was new, sierra, but out of the Johnson gearcase. I put it in last year but never used the motor. Thought I’d be good with that, then after the swap, and first overheat, I thought it’s possible it would be slightly different. Then I put the old one back in to see if that was the problem. I inspected the water lines/grommets. One grommet was smashed in so I replaced it with a different one. Greased the copper tubes before installing gearcase. I did not blow air through it, however I pulled the stat out and cranked the motor it pumped water to there. When I pulled stat it was hot, I watched it move as it cooled so it’s not stuck. I didn’t think you were being rude, your trying to help me figure it out, thanks. The white valve is under it, and springs.
Al, I was wondering about that, it didn’t seem right when I was doing it. That’s why I was sure to mention it. I also replaced the housing/driveshaft seal and used sealant there. Should I pull that too? I did clean that hole when I had the seal out. Does the impeller plate need sealant under it? Is there an issue using sierra parts? I used seal kit, seals, impeller.
