I'm looking for the best ss top speed prop for an yamaha 115 hp on an alumacraft 1860 all welded. Which brandname and size would be the best for top speed gain.<br /><br />Thanks

Re: Best top speed prop for Yama 115

Ahoy, Anglersur.<br /><br />It sure would be nice if it were that simple.<br /><br />Start by optimizing your hull balance and condition. Then find out what "X" dimension (height of engine) gives you the best WOT without ventilating on turns. A hydrofoil can help or hurt, depending on "X".<br /><br />Then you are ready to spend big bux for little gain, assuming you have determined what pitch allows you into the upper rpms of your engines operating range at WOT.<br /><br />There is no magic bullet prop, regardless of advertizing claims. Most SS 3 blade props do well if the pitch is correct.<br /><br />Now, fellow members will explain why they recommend a particulat brand/model.<br /><br />Good luck. :)

anglersur <br />Can't tell you which prop to use for your application, but you might want to check out the link below, which may help you in you size selection. I'm guessing somewhere in the area of 13 X 17 - 13 X 19 for starters.<br /><br /> Prop Selector
