"I have twin '84 crusader
"I have twin '84 crusader 454's in a houseboat. One seems to run hotter than the other. Produces some steam, but not crazy. I noticed this same engine did't seem to be passing as much water through the exhaust. I changed the raw water impeller, didn't change much. I can touch the exhaust manifold on the other engine with bare hands. Infrared thermometer shows the problem engine to be 50 degrees hotter. My boat needs a bottom job I know, could the pickup on the bottom be so covered as to cause a restriction to the flow that much, if so, why not both sides?"
