Help please. I am out of ideas. I have an 87 Johnson 88 HP SPL motor. The 2 cylinders on the Starboard side of the motor are running 20 to 25 degrees higher than the bank on the port side. I did the following w/o any good results:
- I moved the power pack and coils from the port side to the starboard
side. No Help
- The water pump has been rebuilt. no Help
- I took the thermostats out. No help
- I removed the hoses from both sides and observed that both banks
had water coming out while the engine was running. I also hooked a
hose to to one side of the powerhead and when I turned the water on
it came out the came out of the other side plus the pee hole.
So I am assuming that water is circulating thru the head. Am I missing anything? I don't know what to look at next. What else could cause both cylinders on the starboard side to run so much hotter.
I forgot to mention that I am running 89 octane gas with a 50:1 mixture.
All help is greatly appreciated.
