    Default bravo three questions

    hi there, new member here.

    i just picked up a 21 ft mirage w a 454 and a bravo 3 out drive. i am planning on building a new motor for the boat. i would like to be in the neighborhood of 800-900 hp turbocharged.

    i am not new to engine building or boating, but new to prop boats. i am a jet boat guy.

    how durable or desirable are these out drives?

    i want to run close to 100 mph. am i out of line with these goals?

    what is a good resource for parts i.e. props and gearsets?


    thanks,
    barry

    They are good drives, but simply not designed for 900hp. Best bet would be an Imco SCX or like wise.

    Default bravo 3

    the bravo drive is good for about 650 to 700 hp max. the thing with the bravo 3 is the speed will be down, they were designed for some what bigger boats, for better drive abillity. you can change the lower to a bravo one.

    what kind of speed do you think i could get out of this thing with 700hp and the br 3? or maybe a br 1 lower? 21 ft mirage.
