Re-jet for elevation?

[YmeHP]

Hey, I just bought a boat out of NJ and brought it over to ND. The difference in elevation is 1475'. Do I need to re-jet or do any other changes to my boat? Merc 350 Chev

You will need to lean it out.

Depends on what you have? Make, model and year? MPI?

No matter what carb you have, you shouldn't have to change jet sizes. Just adjust the idle mixture.
Rejetting usually isn't necessary till you get to 5000ft or so.
Also when you get the boat out on the water, do a WOT check to make sure you are propped ok.
