Thanks again for the reply's. One suggestion that makes some sense to me is to go with a 150-4 stroke. The price new is less than a 200 HPDI (2 stroke) and the weight is about the same. The 150 performance on the same boat, recently re-powered was 4000 rpm-24 mph, 4400 rpm-28 mph and wide open, 5500 rpm- 38 mph. I've only had my boat up to 34 mph once and usually the water is not that flat.
