The problem is the = RD-2C prop flange comes with 3/8 id x 5/8 od bushings. The M/T prop has = a stepped hole that is =BE” for the first 3/32” and then goes = to 5/8”. Tracy is not comfortable with drilling out the 5/8” bushings and M/T = adamantly advises against using anything less than =BD” prop bolts with this prop. So, I’m at a standstill until I can get this resolved. The only solution I can see is to press out the existing bushings = and open up the holes to accept =BE” od x =BD” id = bushings. But that would require disassembly of the gearbox and some precision machine = work, possible but not my first choice.
