"Paranoia? M440 FWC. Heads red
"Paranoia? M440 FWC. Heads redone last year, new risers and elbows. Heat ex boiled out, manifold looked good, new thermostat.
I bought a new IR thermo gun and shot my Port engine for fun. Are the following temps within reason?
From front of engine to rear (to include middle of log) temps.
Outboard log; 202, 196, 185
Inboard log; 195, 190, 185
Expansion tank at cap; 195
Thermostat housing; 160
Elbows on top of risers; 120
Hoses; 140
This is at dock idle. If it's hot, would the raw water flow increase underway, thus bringing temp down a few? Impeller was new 2 yrs ago. Not many hours on it, except sitting while engines were put back together last year.
Thanks"
