Chris nice looking boat. How many hp do you have and how fast is it? Do you have any interior pics?

took those pictures in michigan before we brought her home and scrubbed her up... it looks a little dirty in a few of those pics.

Looks good, how fast is it? I have to do something with my interior, just trying to decide what.

Chris

it cruises low 50's at 3000 rpms and 80 - 82 around 5000 rpms it should red line around 5500 but i think it has a rev limiter on it cant get it past 5000 rpms even with smaller props - these are GPS speeds.

I would guess its only a guess 572s pushing 650hp would have a red line at 5800 to 6000rpm. did you get dyno sheet showing wear the tq and hp was at? sounds like your limiters are stopping you from getting to the full 650hp. these boats with 502 465hps went 85 to 87 at 5200 rpm. and being a 96 I would think the drive height was set up for bravo 4 blades and not 3 blade mirage props. my 509 made its best tq at 4800 and hp at 5800 to 6000 which was 650hp with a 1050 dom my 850 bg made 637hp my boat ol24 ran 75 or so at 5200 and ran out of prop at 6000 plus at 83.2 all gps. your motor might want to run at 5800 to 6000 to get to there 650hp. there was the other twin with 600 hp that did runs of 104 and 110 gps maybe there drives are set higher but it sounds like you need to have someone check limiters . I wish I was done to give some info on mine but new tank is not ready yet but as soon as it is it will run even if I have to watch out for icebergs for a test run. I you figure it out, ps my 572's red line is set at 6500 art
