i got a 650sx i had to replace the carrier bearing or what i call the "through the hull seal" so i pulled the motor and put the new one i have a little movement in the sense that the shaft doesn't seem to be 100% round almost like its oval a little will this effect te seal. also the shaft is a little beat up im a little worried that it will cause damage to the seal..any thoughts?? also was wondering if anyone had motor mounts in good shape they could sell me for cheap. also need a new bed plate.. thanks
