So i have this thread going "my merc 470 rebuild" which many of you have chimed in on and helped me tremendously. The rebuild has taken quite long but we have the engine running and it sounds nice.
We were measuring Oil PSI and Water Temp, water temp was at 150f peak and Oil PSI was reading at 75PSI at high idle (2000 to 3000rpm) while we were setting seals. We are using mechanical guages from the auto store. For oil i ended up mixng some 25w40 and Diesel rated 15w40, 50/50.
What would you consider ideal temp and oil psi readings?
