HELP!! Sunsation Dominator 32 Twin 502EFI
 

I have a 2002 Dominator with 2 502 efi
no matter what i try the boat hits a wall at 81 mph
bravo 1 drives with 30 p props
as soon as i try to trim the boat to go faster the front starts bouncing and when i trim down its like hitting the brakes
anyone knows what i can do to get the boat to go at least 87 mph
i tried 32 p props and was doing the same 81 mph but just lower rpm

any advice or someone that as the same boat can help me out would be great
thanks

put 1400 hp in it.....:D........whats so wrong with 81 just a tic over 800 hp, Id say thats pretty good

That style vented hull with (assuming) 502 mags @ 415hp each will never run 87, that boat with 496 HO's runs upper 70's with bravo 28's, so I'm thinking your not really running the 81 you think you are, unless those 502's are blue motors

hummm yes they are 502 efi like the post says
blue motor and it does 82 mph to be exact all day everyday on gps

Yeah you're doing damn well for the 502s if you are running that quick.

how is that good i kno 2 other sunsation with 496 ho s and they are doing 78 to 80 mph
i would think the 502 s would be at least 85 mph

500EFI’s ? 525EFI’s ?

500 efi s

That info should help as Most people above thought you had 415hp 502MPI’s.

What rpm are you seeing. If your efficiently spinning those 30's with the 500efi's you should be mid 80's for sure
