    Question 1999 Polaris SLX engine removal. Any tricks and or do and dont's you wanna share?

    Hi all, Im about to start 1999 polaris slx project. The ski has a bad engine. Before I just dive into this, are there any tips or tricks you could share with me? Does removal of the engine require any special tools? Are there mistakes that are commonly made when someone not familiar with the polaris product works on the 1050 engine and or slx? Any recommendations for finding the polaris service manual? Also do you have any recommendations for a quality rebuilder? SBT, PWC in NY, or other?

    thanks in advance for the replies.

    Mike

    Spend some time reading through my signature links

    Remove the PTO coupler before you remove the engine from the hull. Jet pump and drive shaft comes out before engine.

    Make note of the engine mount shims and how many are under each corner.

    Use multiple parts baggies and label them as you take stuff apart.

    Make notes about what was where, and use your digital camera to document each step. You will be surprised how often you will need to check a photo to see how something was done.

    Have a notepad for noting all the bits you discover need replacing, repairing, etc as you go.

    Unless you are like me. I have all of my engine bolts in a plastic container and can pick one out at random and know exactly what it is for.

    lets say you didn't know there were shims under there, and you don't know anything except the front left had 2 thick shims. would the left rear neccesarily have 2 thick shims also? what are you trying to accomplish with the motor shims? Perfect alignment from the pto to the intermediate shaft? Also, how do you check this alignment?

    Are there numbers marked on the hull near each corner of the engine? Like a 2 at the front left?

    During production at the factory the number of shims was marked on the hull, but I do not recall how far back in time that practice began.

    The jet pump defines the alignment. The drive shaft is aligned to the jet pump axis, and the engine is aligned to the drive shaft axis.

    The shims are used to adjust the height and angle of the engine so that the centerline of the engine exactly aligns with the centerline of the drive shaft and the jet pump.

    A special 'alignment tool' is used to verify the engine is indeed correctly aligned. This tool is simply a very straight, very precise steel rod with one end turned down to fit into the drive coupler.
