You also have to change the transom stuff. Alpha transom does not mate to bravo drive as far as I know. Better also research the cutout, could be some small differences...and while it's all apart check for transom rot.
It's a very worthwhile project, allows much bigger torque.
I have a 87 Hallett Vector Looking to swap a bravo one in place of the sterndrive engineering alpha drive Will this work ? Looks to be a newer bravo one unit
Hi, There are several things that need to happen before you can swap in the Bravo1. First you must replace the entire transom Assy. Meaning the whole Inner and outer Gimble housing and you'll have to fit the new yoke in too. Alignment must be within.005" straight. Also you'll have to redrill the transomAnd fill 2 of the old holes. You must use a jig template for proper alignment. Plenty of people will tell you otherwise but it not there boat is it??? Next comes the shift shaft and plumbing. Then you can start to fit it in. It a lot of work but If your not pushing 400+ Hp, really why bother? I have both my alpha 1 gen 1Original drives and have had no issues.
