Stiletto Prop for Yamaha 70 TLR

I don't have a prop yet, and I've never run this boat with this motor. I am getting ready to splash the boat after a lengthy refit and have combed through the threads containing relevant advice. Based on previous discussions herein, I was thinking of a Stiletto stainless advantage 13.25 X 17, but it just looks big and heavy to me when I had the chance to handle one in person, which is hardly a scientific conclusion. Does anyone with a 70TLR on their 16 or 17 have some experience or suggestions? I recall some have gone with 15, 17, and even 19 inches of pitch. Edited by Tom W Clark on 09/10/13 - 8:37 AM

A 17" pitch Stiletto Advantage (I assume this is the model you refer to, not the Stiletto BayPro or Star) would be way too much pitch. Ideally you would use a 14" pitch, but the Advantage is not offered in even pitches so it's 13" or 15" You can buy the exact same propeller in 14" but you have to buy the Yamaha branded Performance Series 3-Blade, part #MAR-GYT3B-V4-14 You could also use the Stiletto Star, but it is even larger and heavier than the Advantage.
