I have a bad vibration in my Port Shaft, I am going to prepare for a haul out and want to have new cuttlas bearings, shaft zincs, etc on hand so that if the shaft is not bent I can install new bearings etc.

I have a 1975 B31 with Gas engines and 1 3/8" shafts is there a standard outside dimension for the cuttlass bearing?


Thanks Clay

I just did mine and the 1 3/8 bearing was 1 7/8" O.D.
