    My SL750 Project!

    Here is some pictures of the engine. I have earlier posted the Thread "Polaris SL750, Denmark" and some of you asked for some pictures. Please add some useful comments to the pictures, if anyone see something that I don't!!!

    Sincerely Rasmus.

    The little blue thing is called an auto-cock, and it causes problems. Polaris recommends that it be removed and discarded.

    The fuel pump is typically mounted just under or beside the rear carb. Keep the pulse line to the crankcase short, and without any sag that could allow fluids to collect inside the pulse line. fuel pump must be mounted above the level of the crank case fitting, again to keep crankcase fluids (gas+oil) from collecting inside the pump.

    Are you changing to a triple outlet fuel pump?

    Yes I am..!! But the big blue thing on the picture, under the auto-cock, is that the fuel-pump, which I should chance with the triple outlet fuel-pump or??

    Second photo looks like the clear vent tube for the battery. If your battery has a small nipple on the end, the vent tube connects to that nipple. The other end vents to an outside fitting somewhere near the steering. It prevents battery gases from accumulating inside the hull.

    Third photo is the siphon intakes. When the jet pump is running in the water, it produces a suction that is run through these tubes. One siphon end should be on each side at the hull rear bottom, to remove any excess water that is in the hull. The ends should not be squashed flat, since water needs to get through that metal mesh filter on the end.

    Each siphon tube should also have an elbow fitting in the middle of the hose. These elbows need to be mounted up high under the back seat, so that water does not siphon in the wrong direction (into the hull) when the boat is sitting in the water. Also, each elbow should have a tiny hole in the side. This breather hole must not be clogged, again to prevent water from being siphoned into the boat when sitting.

    Yes, that is the fuel pump.

    Should I just take of the auto-cock and fuel pump and then install the three outlet?

    Is this correct, with the elbows and so on?
