I was told that you should be able to put your hand on both manifold while the boat is been running for a while and be able to leave your hand on them? but I’m on buying a another boat and I tested it and that one got so hot that I couldn’t touch it at all is this normal for a newer with 2006 350 MerCruiser I’m worried about it melting the exhaust gasket?
