Actually on the tight side. I could be anything. Maybe all boats do it. That is the problem and why at this point I need to see someone else's boat data log to compare.

what do you mean your engine is very noisy @ what rpm, and you run the valve train on the tight side, what cam and lifters are in it.

Stock GM roller lifters for 8.1L Gen7, Scorpion 1.8 Marine Endurance intake & Crane Blue Race 1.7 exhaust roller rockers. Cam is a custom for my engine made by Cammotion.
