I'm sure someone on this forum has converted an OS .21 XM to an inboard and run it in sport hydro such as the club Sport 12 class. Can anyone tell me if there is a pull-start for this motor? How about a 90 degree header and pipe? How about a collet? Other suggestions appreciated. Maybe a Novarossi .21 T21-3M/2 Marine Engine, but what are the RPM and horsepower specifications? I'm trying to get buy cheap. I may be looking for a good, used .21 inboard if anyone has some offers.
