    Default engine mounting questions for high hp

    I am getting really close to dropping in my twin turbo motor. It should have close to 1200 hp. My boat is a 86 liberator daytona heavy layup (900 with pump) and only has 1/4 stringers. I am not going to go full stringer since the tunnel and the wood floors make the boat plenty strong. Anyways can I get away with the normal rail setup, or do I need to box the stringers. I was also thinking of a pump brace. What are you guys doing to keep your motor in?

    If your moving forward with that much HP in a 1/4 stringer boat , I would say definatly to a rail mount system and yes a pump brace as well Tom

    Brace that mofo in there as best you can. Definately a pump brace. I want to add one to mine eventually, probably the same time I do a jetaway.

    2 1/2 x 2 1/2 x 1/4" thickness should do ok IMO. Others out there have probably forgot more than I'll ever know though.
