I have a 2002 Donzi 22ZX with a 350MAG and Alpha 1 outdrive. Right now it has a 4-blade 21P prop on it. Out of the hole it is a dog, top end it will run 57mph at about 4,800 RPM but it takes awhile to get there.. Wondering what guys are running with this set up or any suggestions on where I should go from here. Any input greatly appreciated!
