I have a friend who loves his old four winns 241. It is powered by a mild built ford 460. He has been going through gear sets in his OMC drive and is contemplating a bravo swap. My questions are, does anyone know if the bravo transom plate and omc bell housing will mate up properly? And what do you do for a sea pump (there is no room in front of the crank to add a crank driven pump)?

You can use a rail or offshore mount configuration but you will probably wind up with the engine forward of where it is now. That would mean a longer input shaft and room to move in the bilge that he doesn’t have.

Sell the boat and start over with a bravo boat. FWIW a friend of mine is a marine mechanic and he owns a Donzi Crossbow with twin 460's and OMC's and we discussed it several times and he never swapped over. He just stockpiles OMC Cobra stuff off Craigslist.

Or

Even though it sounds crazy, swap the driveline to a bravo setup and a mild built 454 swap out. Yes, he is dumping the Ford but it will significantly reduce several other problems...

After thinking about it, it would be pretty easy to make an inner transom plate that matches the bravo bolt pattern with OMC fly will cover mounting locations. Piece of cake.

I thought I saw that someone made a kit to do that?

No experience with it, but there is this....

827691A1 $1025.00 VOLVO TO MERCRUISER TRANSOM ADAPTER TEMPLATE / PLATETransom Adaptor Kit converts older Volvo AQ transom hole to accept Mercruiser Sterndrive - no returns

That won't help. The OMC cobra is nothing like Volvo AQ. Actually the cutout and hole spacing are the same for bravo and omc. My issue is the inner transom plate mating to the OMC/ford bell housing.

I know nothing of the OMC inner transom but I'm just throwing this out there... if the bolt spacing on the Bravo is the EXACT same as the OMC, would the t-plate from the OMC work for bolting up the Bravo.... then the considerations to contend with are the # splines, length of the input shaft to mate into the coupler and the X/Y/Z location of the input shaft in relation to the coupler going from Cobra to Merc.

My $0.02 is that the cost of shop time will always out do the possible return on investment - sell the boat running and buy the boat you want with the Bravo and you will be $$$ in pocket

I recommend calling George at AADS. He knows more about these drives than just about anyone. He may even have some tricks to do the swap.

The spacing from transom to block bellhousing is different. Not sure if the height is the same either. Haven’t done the ford swap, but did do a sbc omc to bravo. Had to change it all.
