    93 SL750 best impeller

    I need a new impeller for my 93 SL750 long story short stub shaft backed out............ What's the best impeller to get a good hole shot. Not to concerned with top end but really want to rocket out the water!!

    Your best bet is to find a whole pump from a 94 or 95. It is a much better and more efficient pump, and will give you a lot better acceleration. If you really want to upgrade, go for an extended version.

    So the stock impeller is pretty good then?

    When I had my 93 750 I used a skat-trak impeller that was one degree higher in pitch than stock, it had enough power to pull it & gave a little more top speed & holeshot didn't seem to change, the original impellers were made by skat-trak were 17/20 pitch. If you concerned about holeshot I would stick with original pitch or maybe go down a degree in pitch, a 650 impeller is 15/18, which in theory should give a much better holeshot, but would cost you about 4 mph in top speed & you might be bumping the rev limiter then too.

    I really like how the 13/18 skat trak works on my 750. Good top speed and good hole shot. I like it better than the stock 079 impeller.

    He is talking about a 93 though, with the non modular 146mm pump. Upgrade to the 148mm modular pump from a 94 or later and it will be a lot better throughout the whole speed range.
