I had the patriot on my 100 when I first installed my motor. It worked, but don't put full power on take off, mine cavitated, slipped out like a boat that lost it's grip. The rpm's went way up, I caught it before it did any damage. but I was just coming off the runway when it did it. I heard of it, so I was kind of waiting for it, I backed off the throttle and it caught again. I went and ordered my medium and would not trade that prop for anything, I love it.
