What kind of outdrive is this?

I may be looking at a 1978 Python that the seller says has a speedmaster drive on it and the boat was set up for a BBC
What kind of outdrive is this and how much power can it hold. I'm thinking of putting a 330 HP twin turbo SBC in it that I have.[ATTACH=CONFIG]530816[/ATTACH]

my GUESS is sternpower. They were supposed to be good drives, but if you blow it, how are you ever going to get parts when you cant even google a pik of the thing??

Can you get a closer shot of the transom assembly on the outside and inside the boat also?

Volvo with a speed master foot? If it is very rare and no parts.

Looks like a speedmaster 3. Definitely a 3 lower. I know that cause I have one for decoration.

14/15 or mc-1 . Under the cav plate the 14/15 has kind of a box about 4 inches wide and down the back towards propshaft is thin. A mc-1 has a box about 5 to 6 under cav plate and a thick back towards propshaft. Hope this helps or I'm close.

Looks like a Mercruiser Model 2. My 1969 Sea Ray Pachanga had one from the factory. It was changed out in the late 70's for a pre alpha.

Little off your topic,,,,, but a twin turbo small block with only 330 HP??????

phughes69 10-12-2014 05:37 AM

Obnoxus, the engine is out of another hull I got. The engine is a 1979 260 hp sbc with a M&W turbo kit on it. According to the literature I found it only adds 50hp to the base engine. I ran the boat yesterday for the 1st time and was seeing 4lbs of boost. It is a blow thru carbed system. It designed to be pretty tame so not much modification has to be done on the engine.
