Thanks MAKOMARK.

I replaced the cam in the raw water pump and that little change fixed my heat problem. I went 12 miles today and it stayed same temp as my other motor. THANK YOU SO MUCH FOR GUIDING ME THRU MY ISSUE.

Glad to help...that's one of the drivers that lead to the question "When was the last time the raw water pump had a major service kit installed?"

FWIW, figure on the other pump needing the same attention soon...no later than the spring recommissioning in 2024...
