Larry,

Basically, you would take the alpha outdrive off, and replace it with
a bravo outdrive. The engines are identical, but the outdrive is totally
different.

I think that the Alpha is rated at up to 300HP continuous, so the only
reason to replace with a Bravo is if you've added some real oomph to your
engine.

Do a google search on Mercruiser Bravo outdrives, and you'll find places
that sell them as well as Alphas. They are somewhat more expensive...

Have fun,

Don W.
