    seems that propping it too 5900rpm is the fastest maybe best powerband for this engine
    al other props rev the engine up higher

    You are going to be into the limiter somewhere between 83-86 with the 28 Bravo. There are a few on here that run a 250 with 1.75 gears hopefully they will chime in.
