Hybrid boat...

Its a hybrid, it burns a little bit of fuel at the dock, and a **** ton when you get on it!:D:cool:

I bet it took 5 gallons to prime that motor!:D

That's a 650hp Rolls Royce V12, if I lived on a lake I'd crank her over at 5am on the weekends...:cool:

I don't know maybe Allison V12's for a boat?:D

Their was one in the Thimble Islands with triples that's now re-powered with Cat diesels. Right after the war the owner put in triple LM2500 Packard V12's because he wanted his milk to be extra fresh every morning!:D It might have burned 300GPH+ but it got him his milk super fast...

Nice ride, these are even sweeter with Allison V-12s a lot faster too.
