This is me in Bristol 1982

The only lower unit failure I ever had on a Mercury was the rear bearing carrier on a first year propjet Merc 500. Broke and every thing but the pinion and forward gear came out. This happened in very shallow water at Key West and I recovered everything but the shift cam follower. Taught myself how to build lower units after that.

Lars asked nicely, this is an OMC thread. If you want to post about Merc, go to the merc thread.

the gearcase in this picture is actually a V-4 case modified for the rotary. Note the exhaust cut out and the black adapter plate between the case and the bucket. This was used for the Provo race and later a rotary only casting was made.

Lars, Is this a billet brg hsg or stainless??? The originals were cast aluminum even in the race engines I would imagine. Stock gear cases were not designed for surfacing I guess. I had a Johnson V6 on a bass boat w/hydraulic 6" jack plate that wore out the g/case and brg hsg...had to replace the assy. Is it only the OMC's that have problems surfacing the g/cases or do they all have the same problems?

Pretty sure its billet, not SS. Some OMC production gear-cases had some issues. My experience was mainly with the "nitro" back when they came out 1974/75.
