    Buying 95 Polaris 750slt help please!!!

    It has a hole in #3 piston center pencil size how far can index be off when measuring piston #1 and #2 with #3 at tdc. I already have #3 piston out so I can get it pretty close and the differance is between .010 and .060 thousands.

    Could it be something else like fuel pump or clogged carbs I order the 780 fuel pump and need to know how to install and plum and what else I will need to do the job. Any other info whould be great.

    Thanks

    mboley WELCOME to the Green Hulk Forums!!!
    If you're running a single outlet 780 pump it's a direct replacement.
    If it's a triple outlet pump, this diagram should help you out.

    Welcome to GreenHulk. My guess is the fuel pump. The best pump is the 780 one. As for installing it, check out this...

    As you can see, a seperate line goes into each carb and one return line goes back through all of them. Hope that helps, you'll find there are a ton of great people here to help you so don't be hesitant to ask. Good luck!

    The best way to check the crank index is with a degree wheel. The cylinders should be 120 degrees apart within plus or minus of 2 degrees.

    Thanks guy's

    I think my buddy ordered a single outlet polaris 780 fuel pump from polaris for 155 dollars I was hoping this was the problem.

    I will see about the degree wheel but I don't know if my buddy has one
    I know I don't. But how far can it be off the way I did it.

    Thanks for the help sorry it took so long i'm still on dial up!

    i didnt think they still had dial up service , personally i would buy a junk polaris just so i can have these help full guys hook me up , ther like brothers once you post with a sea lion under your butt ,

    anyways a whole in the piston is bad bad bad news , but iv seen fair share of cheap and expensive parts , lucky for you , you have the fuji type motors and there parts are super easy 2 find and not every body thinks they are gold ,

    hope you have fun on it when you get it running and dont let that dial up keep ya a stranger

    If I have to replace the 750 engine I don't know much about them!

    Is their any one in Louisville, KY or Southern Indiana that could do it. I called s&s powersports of southern indiana and they said they don't work on polaris jet ski's?

    If you can change your own oil and replace you brakes on your car you will have no problem putting that engine in yourself. My local Polaris dealer will not even talk about there watercraft, little alone order parts. But with the resources her at the Green Hulk, anything is possible. Just look at my project.
