In making long range plans for the build up/restoration of my Formula 255 Liberator, I have come to the realization that "power to the water" will always be limited by the Alpha drives. The logical move is to stay with my current 260~300 HP 350 Chevy set up but make the change to Bravo drives.
On the surface...I know that I have to replace the gimbal/transom assembly as well as the drives, the coupler, the flywheel?,add the raw water pump cooling set up and possibly go to the closed cooling set up.
Is there anything else that I am missing that is obvious? Is the transom opening the same?
I am lucky being in South Florida where used parts are plentiful and I see used gimbal/transom assemblies for sale regularly. Is the gimbal/transom assembly the same for Bravo 1, Bravo 2 & Bravo 3? I obviously know what makes up a Bravo 3 but I am curious as to the difference between a Bravo 1 & a Bravo 2. Will a Bravo 1/Bravo 2 reliably handle 450~500 HP? How about Bravo 3?
Is it realistic to think that I can put twin Bravo 1 or Bravo 2s, A~Z in my boat by shopping the equipment (used)...for around $4k~$5k? Based on what I have seen for sale ...it seems possible but having not done it...I don't know.
I know that the design of this hull with 750~1000 HP will always be limited to a max of about 75 MPH...which is about as fast as I would want to run it anyway. I would like to be able to run 60~65 MPH comfortably for long periods of time with out pushing the limits of the power. I'm thinking strong 383s or LS-1s.
All thoughts and suggestions are welcomed.
