Question Prop Rotation

I am running a 25' daytona w/ twin 2.5efi. The props are turning in towards center of boat (when looking at the props from the rear, the left is turning clockwise, the right is turning counter-clockwise), running 28" Cleavers. Does anybody know if it would run better by turning props towards outside (when looking at the props from the rear, the left is turning counter-clockwise, the right is turning clockwise)?

Thank you

all combos are different.

Your hull will run a bit faster one direction or the other. Gotta try them both to see. Generally, IN (like you are currently running) makes the boat handle a little weird in dicking situation since the engine is not "helped" by the prop rotation in pulling the stern around.

Couldn't resist this one. You should try and do one or the other. Either handle the boat or handle the "dicking situation".

As I understand it Cats like to ussually turn in and V's ussually like to turn out. This is for handling but does not neccassarily mean speed. You just have to try and and see what one is best as they are all different.

Very generally and in my case, turning in on a cat is faster acouple MPH, but increases the outside lean in turns. Turning out may help it handle better, but at a cost of speed.

I found after testing both ways, the MPH wasn't worth the chit in my pants during turns, so they're turning OUT!!

With Bravo outdrives its easy to check, with outboards...

Good Luck and be careful!
