I think you will like them. I have been using one on a 150 Evinrude for several years. The only thing is, they will ding up much easier than an aluminum prop, so figure replacement blades as an annual expense and be sure and check the prop if you dust the bottom, even a just little bit.

My brother brought the boat home from a night fishing trip one time complaining of low power and overheating. He said he had hit some mud and maybe sucked some in the intake. I looked at the prop the next morning and the blades were down to about 1" long. Motor was fine though. Changed the blades in a few minutes and went for a ride. Didn't invite my brother.

I used one for a day and I threw it away. I lost several mph off cruise and top end even though my RPM's were right on target. The boat was a 26 CC and the top speed was 42 with a SS prop. Dropping from 42 to 38 wide open and dropping from 31 to 28 mph cruise made me feel like I was crawling.

Did you talk to piranha about it? Maybe they sent you the wrong pitch or something.

I do believe the plastic prop will have more drag than equivalent stainless, but I wouldn't expect that much performance drop.

After the one trip offshore I got rid of it and bought a mercury ss prop. The pitch was same on the SS and the piranha. A different diameter and pitch might have gotten it up a little bit, but I never sent it back to get a different diameter. I was thinking it was more of an issue with pushing a 26 foot deep v. I just assumed there was more prop flex and it lost efficiency.
