Default Avanti 22 speed vs.hp

I know a few people around here have had them in the past. Right now Im running a 454 330 mpi and with a generic 23p 3 blade Im seeing about 55. At that speed the boat handeling wise feels like its starting to work good. I would like to see a cruise around 60 without having to wring the motor out. Any guesses as to what I need to look for total hp wise to do this??

See this is whats confusing me, the thread mentioned states one will do 70 with 420 hp, PNP states that 575-600 will almost crack 80, yet with 330 Im seeing 55.

This is all over the board, 90 hp is a jump from 55 to 70, 15 mph increase, adding 150 hp from 420 to 575 is only a 9 mph gain..

The math isn't working for me and I would really like to get a handle on it to build or buy once and achieve my goal.

That's because hp and speed don't have a linear relationship.

but it runs off and hides from most small boats especially when it gets rough.I have found dragging a little tab to be very beneficial.

keep in mind I don't care what the boat will run empty , outta gas on flat water and me in a banana hammock.. lol I'm an all around type.

also every Baja goes 70-80 where I'm from but I've yet to see em go on by lol.

also ihave run just about every prop on it I could get. 5 blade and 6 blade included.

by far best for handling and overall running has been bravo one unlabbed.
hydromotive props sucked on my boat.

maximus was a no go.
