Is it posible to put b1 lower on b3 upper? Can you install b1 on b3 transom assy? Dumb question i know! Thanks
Jason

yes

All Bravo uppers and transom assemblies are the same Yes you can mix and match.

Thanks! Upgrading engine for more power and was wanting to get away from the b3 for more prop picks! Thanks again!

Be aware of gear ratio issues......A BIII 2.0 is a 1.50 BI. You may have a 1.81 or 2.2 BIII (1.36 or 1.65 BI)

My b3 2.0 so i will need to find a 1.50 b1 lower?

No.....any lower will work (gear ratio in upper). For determining the prop you'll have a 1.50 complete BI.

Be aware that there was a generation of BIII drives, that had an upper that was a bit different. The part above the cavitation plate extended out, the full length of the cavitation plate. I have only seen this drive a few times, so I don't know what year they are form. But the BI should bolt with the drives that looks like the one on the left.
