Hi Guys, I am repowering my boat which is a 16ft Spectrum Alumn.I now have a 1995 70hp Force and I get about 35mph The Suzuki dealer thinks I should have a 50Hp DFI 4 stroke. He says my Force 70 would be about the same as their 50 whick is rated Hp at prop. I have also been told that Force after 1993 Is rated at prop also. I am afraid the Suzuki 50 might not be enought, any bigger 4-stroke the weight goes way up with a 60-70 hp.Any one familiar with those motors, any advice would be greatly appreciated. Thanks Paul
