Hello all - I've got a 2002 F225 TURA on a GW 228 Seafarer running out of Pleasant Bay down on Cape Cod (That's Orleans and Chatham).
I had an overheating alarm going off only at high (4800+) rpm. Long story regarding the fix (it was multiple issues) but I am pretty sure I've solved that issue.
After doing the repairs, I took the boat out and ran it wide open 5500+ rpm for 20+ minutes. I then throttled back into neutral, popped the cowling off and while idling, used a laser temp gun to check temps. Starboard side was 156, Port was 170 (both measured from the top with the flywheel cover off).
My questions:
1. is the delta in temps on one side vs the other normal and/or acceptable?
2. are the temps readings ok for the scenario I describe? Assuming they are as the engine didn't overheat.
3. if the delta in the temps isn't normal I'm guessing I might have a constricted waterflow in the port side. Suggestions on what it is? How do I clear the constriction.
Thanks
Jim
