I've cut a lot of props, you would benefit from the slightly wider paddles of a cut down 16 inch, but I feel you wouldn't notice the missing 1/2 inch on either end. It may require a little more off to compensate for the wider paddle. Zinger makes a 16/5 that you could cut, the paddles aren't as wide as the 16/4 APC and that one inch off just might do it. But it is a wood prop. I ran the 16/4 and the 15/6 on the Saito 100 and now use a 16/6 and a 17/4 on the YS 110. Joe
