    Polaris Pro 785 saved from the scrap

    Hi everyone,

    I stumbled across an ad for this jet ski. The owner wanted it gone that day or it was going to the scrap yard.
    I saw the 2 stroke expansion pipes and couldn't resist buying it.
    The owner said it came complete and had seized the piston.
    After giving it a good wash it came up pretty nice. I slowly tore everything down over the past few days and planned to pull the motor to see the extent of the damage.
    It took a while to tear it down. Most of the fuel lines are hard as a rock and very difficult to remove.
    I managed to lift the motor out with an engine hoist and broke it down further.
    I found the barrels to be in reasonable condition (from a quick glance) and a very damaged piston rod.
    The piston rod failed at the connection to the crank shaft.
    For now I'll find out how to locate/set the timing, pull the fly wheel and look at the crank better.
    Photos so far are attached. Hopefully I don't find too much more damage and hopefully I can rebuild this beast.

    Stay tuned for more progress pics.
    Jack

    Welcome to the Hulk.

    You lucky son of a gun.... That's fantastic that you saved it from the scrap heap. Previous owner has no idea what they had.

    That was an old race boat and is completely tricked out.

    It's not going to be cheap to get it back to running though, just letting you know.

    Where was this located?

    Fixing a pro 785 is always worth it. This one has everything, it's got so much potential.

    Thanks for the link. I'll have a good read.
    I'm located in Australia. There isnt much information available in this country about this machine.

    So far I have broken the engine down and am ready to pull the fly wheel. I'm in the process of making a took to remove the fly wheel but I wanted to check if there is any timing/flywheel locations that I need to mark out before I remove it?

    So far this is my parts list but I'm sure it will grow..
    > Crankshaft (Preferably rebuild the one I already have)
    > Pistons and rods
    > Gasket kit
    > New fuel lines and other lines (Most were loose at the connection so I'm sure this wouldn't have been running right)
    > Service Manual (Pleeeeeaasssee direct me to a service manual that available online if anybody can help me?)
    > I'm sure much more

    I think you already have the link, just work your way through your good read.

    IIRC the Pro 785 flywheel is indexed on to the crankshaft with a woodruff key. No timing issue with removing the flywheel.

    Note that the flywheel puller tool may need to be quite stout. Some flywheels are really stuck in place.

    Tip: Loosen the flywheel nut 2-3 turns, but leave it in place on the end of the crankshaft. This prevents the flywheel from going into orbit when it lets go.
