Unless he changed the prop I ran that prop on my boat. It was Grizzs that was on loan to Scot. It ran fine for me with no blow out to speak of. I also remember Scot not getting more than 55ish out of that boat when he ran with me. I got a 26p turbo from grizz. Vent holes open. Gonna try it on my bigger boat. The guy I loaned it too said it caused cavitation on his though.
