1998 4.3 Mercruiser Alpha one Outdrive: Raw water cooling
Temp alarm sounded @ 175 Deg. while cruising at > 4500rpm.
When I back down to 3800 rpm temp is steady @ 160.
Is 175 a high temp. or is my alarm going off prematurely.
I did hook up the muffs when I got home wasn't able to get the temperature alarm to sound of course there was no real load on the engine.
I did notice that the starboard exhaust water was significantly hotter than the port. But like I said the temp never got above 160 with the muffs.
Any Input is appreciated.
