OK guys here’s the problem, new to the whole boating thing and just rebuild my first boat. Took it for its maiden voyage last night after the rebuild. When running WOT I’m only hitting 3,600rpms. My buddy, who’s a mechanic, came over 2 nights ago and we had it running on muffs and was pulling 5,000-5,200rpms. I know there’s no resistance from the water but this doesn’t seem right to me. When running it towards the end of last year, when I got it, was getting about the same rpms and I just figured the tach wasn’t right. Any ideas of where to start/what to look for/at? Motor is an early 80’s Merc 40hp on a 17’ Sea Nymph Bass Attacker.
