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

I think your gonna need a heck of a lot more power to hit 80 in a non stepped 32 sunsation. Def not happening with l29 heads and the current setup.

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.

I have been on a few 32s, stepped. One with 450 hp 502s, gil dry exhuast, that runs 81-82. Other one had 310hp 7.4 mercs, that ran upper 60s. Other buddy has one with warmed up HP500s, extension boxes, and shorty lowers, and runs mid 80s, also stepped bottom.
