I ordered the parts I thought I needed from the drawing. The bearing carrier assembly came with all the bearing and seals in the unit so I need to return all the duplicate parts that I ordered. I need a return address for the return. Please send it to ( roun2it@abe.midco.net) THANK YOU RICHARD

Problem fixed: Broken gear housing.

The lower unit on a 120hp Force outboard motor had water in it and it froze pushing the gear housing out breaking the tabs off the housing. The bearing where rusted and stuck. I ordered new bearings and the bearing carrier assembly. Assembly went easy after I got the old bearings off the gears.
