    Yes it should be a direct swap. I would find a 94 or later pump to put on there however. The 148mm pump is much better than the 146mm that's on the 93s.

    would the driveshaft be too short from the sl to the slt? or are they the same

    93 750 sl to 94 slt engine swap

    Will I have an issue with that prop from the sl or will it be like I just have an extra passenger on board?

    Not sure how the SLT will handle the 93 750 prop. The 94 750 (079) does fine on an SLT with one rider. Trouble is, with the older style pump, you are going to have more of a challenge finding different props. I can probably get together an average condition jet pump with a prop for a good price, but it will need a stator rebuild kit..... PM me if you are interested.

    See my signature links for details on the jet pump versions.

    Just to be clear the 1992 and 1993 jet pumps are a very different design that the 1994 and newer pumps. Your 1993 pump is a 146mm NON-modular design.

    Polaris changed to the much better 148mm modular design starting with 1994. Pump sections are interchangeable and overall jet pump efficiency is higher. Not just a 2mm size difference, a much different design.
