I bought a used Mac .21 from a fellow board member here earlier this winter and just today got a chance to run it.I put it in a Seaducer with a 437/3 and AB pipe at 8 1/4 inches and 60% Byrons fuel.Needle was the same start as my previous Mac was in that same hull.First run the boat ran good and got on pipe right away but fell off after 2 laps but still ran pretty good then died.We retrieved it and found the plug bad(which was new),pretty mangled inside the plug.Second run I richened it up 5 clicks and ran good longer fell off and died.**** was it fast.Plug was the same.Third run we went still richer ran really good 4 laps it stalled.It was retrieved and plug was the same again.I was told the pipe might be short so I went from 8 1/4 to 8 1/2. I went to start it and couldnt turn it over with the starter or by hand even with the plug out.It was able to turn with a wrench on the collet but after truning ot over a couple times still will not turn by hand.I dont think it was froze solid but definatly stuck.I had good flow from the water outlet and was not hot to the touch.I could hold my hand on the head after the boat got into the retriev boat.Any ideas?Bearings?Motor was smooth when I got it.Should I go after the seller?Not half a tank and the motors needing new bearings or sleeve/piston.Thanks
