So this is very vintage. Was on house boats, to big cruisers, and a few offshore boats back in a simpler time. I don't have the heart to junk it. So it's in my garage and taking up a lot of space needed for other projects. I have everything as it came out of the boat with 530 original hours. Shipping will be bad as the drive is heavier than a bravo three. But can strap it to a pallet.
this has a velvet 1-1 to mate up to the inner plate. As the drive didn't shift. Prop is the same size as a bravo two 21x20p

Looks to be the old aka “club foot” mercury drive. Used on houseboats and heavy duty vessels.
