    785 back to stock, impeller Q.

    Have yet to have this thing run worth a damn. Going all new motor back to stock (had head, and carbs). Pulled the pump last night in prep for engine removal and found it has Skat Trak 13/18 (decent shape). I know it should be at 12/17 but what can I expect? Rememebr I have 0 expeirence with a good running Pro. Also, my friend has a SL780 that needs pump work and according to Skat's advisory chart, 13/18 would be good on his. Would mine fit his?

    always start with a 12/17 for any testing on a pro ,if you cant spin that then something is wrong and yes the 13/18 will work in his ski
