I need some help. I have a 99 Johnson 115. the right side is over heating. I changed the water pump. pulled the thermostats. checked the water flow ran a hose down the input and the out puttt there does not seem to be any abstractions and still the right side gets hot left side fine is running normal temp using an heat gun to check. compression is good all 4 cyclers are 145-143 can anyone help me on this. the. the only thing I can think of is to pull the head and my look for some sort of obstruction but like I said. I ran water both ways I tried to run it with no thermostats when doing that the left side would stay really cool at 2500 rpm it would read 101deg. 10mins run time right side would just rise. I am stumped. sorry for any bad spelling and grammar I am dyslexic

I don't know if running lean on one side could cause it, but it might be a good question to ask an experience outboard mechanic.


It seems to me that anyone who wants to force upon the rest of us the character of sheep must himself be a wolf.
