usaski1 Posted May 2, 2012 Share Posted May 2, 2012 Thought I'd pick the brains of some BOS'ers and see if any ideas come about: I have a boat that is slow. Tops out at 38.8 or so mph on gps. Turning 5020 rpm, on a 13x13 3 blade OJ. No bad vibrations. Changed spark plugs, (and gaped them) today, no improvement. Feels kinda weak out of the hole. Indmar 325 EFI motor. 86 hours on the motor. Also seems like I'm getting poor fuel consumption. 30mph is 3700 on the tach. Thinking it might not be the motor if im getting 5k out of it. tranny is 1:1. Died 3x in the last 2 motor hours at idle. Ideling 650. (normal) Any leads? Link to comment Share on other sites More sharing options...
