Hello,
Referencing the above engine, I have just replaced water pump imp, gaskets, and thermos, and springs under thermos. With infrared heat gun got the following running on hose.
time...left...right
0min...86...86
1min...103...103
2min...110...113
3min...114...117
4min...114...122
5min...115...125
6min...117...126
7min...117...127
8min...117...124
9min...116...125
10min...116...126
checking block temp about 3inches forward of where head bolts to block after 10min left...125, right...152.
The head on the right is a different head than on the left. It has higher compression in cylinders than the left head (105's vs 90's). I don't know why it was replaced, but would a high-compression head run hotter than a regular head?
Question is, I think this motor has run this way for many years. Should I worry about it? Is there anything I could do that would help its longevity? When I got it, there were no springs in the thermos, I put them back in. Should I shorten them on the right side to see if that makes a difference? I have not run on lake yet, so going to higher rpm I would assume heat things up. No alarms have rung on the hose.
I just had the powerhead off to replace the exhaust gasket. That project was not as bad as I thought, so I'm game to do more, if necessary.
Thanks much,
Winfield
