What prop would you recommend for 4800 rpm capable of 80 mph on Sunsation dominator. Currently mirage 25 3 blades on 1.5 bravo. Boat is 94 so not step hull. #11 ever made

heads have the vsa7 springs from comp products. Believe they are zz502 max lift 610. Rotator eliminator a as well.
Should be a nice clean and simple reliable package. Without a doubt it could be woken up with just a cam change but.... Heads should support another .100 lift I would think and prolly pick up an extra 40 plus horse easily without hurting reliability etc. Regardless I think everyone's on board with the 400 Plus or minus. I would imagine comp is near 9:1? At least you can go out and enjoy the day. Drink some beer, looks at some bikinis, and call it a day. Leave the tools in the shop.
