RE: Aquacraft Super-Vee 27 Nitro.
I have been running the GrimRacer 40x53 2 blade prop and 30% Grim Racer Fuel I get it in quarts from Tower Hobbies no boat support around me either.
I don't race or anything just run for fun. It has been working well for me.
I am installing a new flex shaft I got from OSE with the Kintec racing 3 piece coupler. The only problem is they sent me the one for the electric version just emailed them to see about getting it swapped out for the right one.
I am also going to install their adjustable trim tab brackets with the water intake in it. My plastic bracket is cracked for my cooling water inlet now I figured it would be a decent upgrade. Has anyone else used them?
