So last year i repowered. 5.7 psi pwtr. I was unable to make any trips as i have been chasing an overheat per my gauge.
Things I've done. I have replaced every hose. New Thermostat. sea water pump. New threw transom fitting. new outdrive hoses. VP sx-M. New seals in the lower.
I installed clear hoses on the sea water pump to look for air bubbles. bubbles are present.
I thought it might just be my temp gage and sender so i installed a new gage sender and wire.. no change
My temps running on the muffs hang at 160-165 then for no reason the gauge climbs to 180-190.. if i put it in neutral and increase the throttle to 1100 rpm for a few secconds, temps will fall to 150.
I shoot the top of the thermostat housing with a temp gun and its about 120.
The intake manifold closest to the temp sender is 112-115
My port riser is about 98. my starboard riser is 125. taken on the top.
My risers have always varied in temp.. both are brand new.
Im stumped, My temp gun readings on the motor indicate im not to hot but the gauge says hey dummy don't cook your new motor..
Any thoughts are greatly appreciated..
