I'll take the housing off and double check. Is there a gasket there that needs to be replaced or sealant? Or can I just take it off and put it back on?
What would be the best way to check the impeller output in the water?
I talked to Mercury again, different person. They said every engine calibration is different but a general number to set the alarm off is 215 degrees. Im not close but I'm also not far away either, atleast on the port side.
I did use a IR temperature gun to get my readings. From what I've...
Spoke to Mercury today. They said they do not have a temperature spec for manifold and elbow. Basically said if there are no alarms or codes then it's within range.
I've read it's normal for each side to have a different temp reading so the difference in temps side to side don't bother me too much. But the 190 makes me wonder. Wonder if I could get ahold of anyone at mercruiser to answer the question.
Yeah I was just trying to do what the manual called for, parts wise. Again it rubs great, I just thought/assumed it should be cooler.
I reused the ball valve T fitting on the bottom of manifold. I cleaned them out before installing but could they be bad or restrictive some how?
Makes me feel a little better and it ran good with no problems. The little bit I've seen online says it should be cooler but there wasn't enough talk and evidence to support that. I have the Merc manual and it does not give a specified temp it should be.
I took the motor temp reading on the housing. I should've done it at the motor or intake manifold. Regular gauge and smart craft gauge both say 150 motor temp.
.Poppet valves were checked and are good.
. Flappers looked good when replacing elbows and manifolds.
.Used a IR temp gauge to measure temps.
.It is a 4 port housing.
.All temps taken with boat warmed up. High number were after a hour long cruise, mostly at 3800 rpms.
.Impeller is brand new.
