My boat is 95' ranger r70 17ft. with a 115hp Evinrude 2 stroke, with a 4 blade ss prop. and my dads boat is a 2000 moomba outback ls that is stock for the most part. He claims his boat tops out at like 48-49 mph. I'm unsure where mine will top out because I just bought my boat and haven't had it out yet. So what will be my top speed and who will win?
