Go for Broke, I started out wth 23 pitch 3 blade Mirage props with 502 magnums (410 hp.), 1.36 drives and ran 69 gps at about 4900 rpm. Fast forward 3 years and 400 more hp. and a change to 1.50 drives, I am in the upper eighties at 5800 rpm running 27 pitch 4 blade hydromotives. I was talked into the 4 blade hydros by a racer who is good friends with Tom Buchnell who owns the company. Plus he pointed out that all the new Fountains at the time were running 4 blade Hydros. So I said what the hell! I have heard the opinion that 3 blades are faster than 4 but if that is so, why do all new boats come with 4???? If I can pick up 2 mph by just changing props...it's done!Originally posted by GO4BROKE
Curt, I run 2mph faster with a Mirage Plus than I do with my Bravo 1's. Doesn't sound like much, but thats all it takes to push the gps over 70mph.
