Hello fellow boaters and gluttons for punishment
My 5.7 IO is running about 180'-190' on one side(infared thermo on riser)while the other side is a cool 135' ish. I changed risers and manifolds,they were 7 years old, but appeared to be still in good shape. same problem, I'm much calmer now thanks, I took the lower unit off, water pump is 1 year old and still good. The 3/4 X 3"riser tube coming out of the water pump has exhaust residue on the inside, is this normal

Any thoughts Thanks for your input
