Raptor 400. We ride at near sea level. I was responding to dillyrev regarding elevation comment.
Altho I believe this prop is used as the “high elevation” prop
Do you have any vibration or other issues because of the prop being too close to the hull? I want your results. Just don't want to deal with any problems.

I have not noticed any vibration. And I have not noticed any gel burn either. Tbag (earlier post in this thread) used the same size prop but slightly different pitch I believe and ended up having just a slight bit of gel burn so he installed a stainless plate on the hull above the prop. All depends on ur clearance.
Thanks. I just ordered a B52 so clearance will be the same.

The issue isn't necessarily cavitation it's that the cavitation bubbles can touch the hull when they implode vice imploding before they can touch the hull. I believe larger diameter props actually produce less cavitation for equal amount of thrust. The trick is to keep the thrust low enough that you don't create cavitation.
A 0.6mm stainless plate will protect the hull. Look on eBay- 3m 5200 works
