Prop size, ???????????????

[phoenixhotrods]

Im running 19p props, my boat is light with bottom paint and twin 350's 260hp.
I want to try a 23p prop or a 25p anyone have some input.
Right now at 4000rpm im doing 32kts or 37mph, id like to hit that speed at 3200 rpm

25P and 23P might be pushing it. You may want to try a 21P first. That should get you where you need to be.

No guessing needed. Contact a good prop scan guy, give him your specs and he can tell you the best setup for your boat. If you over prop you will cut down your top end and put unnecessary strain on your engines.
