[QUOTE="thill, post: 378254, member: 4972"] I've been playing with various props on mine, and YES, it can make a substantial difference. I found a lower pitch stainless prop, with a very noticeable cup gave me much better hole shot, AND a couple more MPH at the top end, also. Both of them running right up to 5500 RPM. Very happy with it! I believe I was running a 13P aluminum, and this is a 12p stainless. Both 3-blade. Unfortunately, I got the prop used, from an old parts motor, and I cannot find any marks on it to tell me who it's made by, unfortunately. Otherwise, I'd let you know. And it's not a polished SS prop, but one that looks like it's been wire-brushed. A polished one might give even better performance? Or is that just for looks? I don't really know, actually. Is the brushing like the dimples on a golf-ball, actually raising performance??? I really don't know, but imagine the high performance bass props would all be brushed, if that were the case. But now I'm just rambling about props.... [/QUOTE]
