[QUOTE="jakeman, post: 3565122, member: 10690"] Long time boat owner here. The ever present need for more speed is an affliction that doesn't go away easily. This is what I know. 15 years ago it would have cost me in the neighborhood of $3700 to pick up about 5 GPS MPH thru engine modifications and additions. I decided that 55 GPS MPH in a 21' bowrider was plenty fast, because I wasn't going to spend that kinda cash. So I started jacking with props. 3 blade. 4 blade. 5 blade. Pitches from 17-23. I don't think my actual MPH changed more than about 3 mph from top to bottom with the exception of the 5 blade. That was a speed stealing mf'er, but I could get on top quicker than a hiccup. It was crazy how fast that thing would throw that boat out of the water, but about 48 mph was as fast as she would run. If you're looking for big changes from a prop or pitch change, you're going to be disappointed. [/QUOTE]
