I am replacing the motors in my 29 OL. I have 454 mpi’s in it now I want to upgrade to 502 mags. Has anyone done this swap? if so what did it consist of?

Thanks.

customtouch did it. check with him.

didnt you just buy that boat?

Sure did, I bought the boat knowing I was going to swap the power. Do you have a contact number for him?
Thanks.

do some 500's. that will get you in the low 80's

I have not ruled that out.

make sure with either option you add external hydraulic steering. they dont come with that with the 310hp engines.

I did that to a 26' Donzi a couple years ago,
( mind you, this was a complete engine,
no component transfers)
it was a piece of cake......take one out,
put the other in....everything plugged in,
connected up the same.

Ditto on the steering comment.

Thanks, I have the steering in the plains too

Hey Runnner what was the top speed you got out of your 29 w/ 310's before you sold it?
