I have yet to find any decent info on the selection of skat trak impellers for our '96 speedster. Does anyone know where to get them from and what to expect to pay for them? What is the correct pitch for each prop or should I change to 2 of the same picth. I'm not concerned with losing a few on the top end but would like an improved holeshot and overall better performance. I just can't believe I can't find any substantiated info on this subject and it's the part of the drivetrain that actually makes it "GO".:willy_nilly:
