    Lightbulb Engine Swap 95 SLT 750 to a 96 SLT 780

    First Post and a newb to jetskis, however I have alot of expertise in building superbikes, but the Iraq war ended all that.
    I have a 95 SLT 750 and a friend is giving me a 96 SLT 780 will i run into any problems with an engine swap. I know I will have to swap the electronics as well, but will i also need to swap the jet.
    The 750 motor needs a complete overhaul and i plan on trying to find a hull for it later.
    The 780's hull is toast, something about a pier and beer Lol

    Welcome to the Hulk! I recently documented a complete rebuild and swap of a 750 to a 780. You can view the thread here.

    This is also a great resource for working on Polaris Skis.

    Welcome to Green Hulk... and Thank You for your service!

    I've been through your town a time or two... on the way to a Bama game. I lived in Millbrook/Prattville area while stationed at Maxwell AFB.

    Roll Tide!

    The 780 vs the 750 are basiclly the same engine except for jugs and head, and carb jetting. Throw the 780 into the 750 hull and enjoy.

    Yes just throw the 780 in the 750, carbs & electronics box too. The only change to the pump is put the impeller from the 780 in the 750 pump, actually just take out the pump stator with impeller attached & swap it. The 780 has the extended pump, which is a good performance upgrade, but you need to change out the steering cable & reverse cable & water supply tube to get the pump extension part in the 750.

    Thanks everyone for the tips, I plan on swapping the jet, cables and electronics. Basically gut the 750 hull and replace it all with the 780 equipment. I have to say I used to run on a lot of motorcycle forums and you guys have them beat hands down. I have suggested this site to everyone I know who has a jetski.
