mercruiser 7.4 mpi can't figure out the ratio

For the B3 the Mechanic is correct, so long as the bearing retainer nut is not moved. The retainer nut on the B3 is where the shimming takes place, the carrier just holds the seals

That said shims don't need to be changed so long as backlash is correct

Also it left hand threads
