Pulled off my exhaust manifolds as I had a problem overheating. While the manifolds were off figured I'd check compressions. Checked the compression on my 1986 volvo 225 and all readings were between 45 and 55 psi. does the engine need to be warm to get accurate readings. Engine has been running strong with no apparent engine problems besides the overheating. temperature on the boat gauge read steady at 160 though a temp gun at top of the engine read above 220 in some spots. Any ideas?
