    I agree about mid 70's. Baja has a tendency to set up their boats inconsistently. I owned a 33 1999 Baja outlaw with twin 502mpis. I ran 69 (GPS). Same boat, same lake same props 72 (GPS). Powerboat magazine, 2001, gave an award to Baja for the 36 with 2/575 sc.

    I run with a 33 outlaw W/ 500 carbs and boxes. Speedo says high 70's, gps says low 70's. This is in summer weather. 342 w/ EFI 500's runs .5 MPH faster on GPS in same water on same day.

    try this;
    rpm x pitch x ratio x .0009497 divided by slip in % equals speed. To find slip, use
    GPS to get actual speed, then calculate from theoritical speed. Be careful on ratio, if its outdrive, the prop is underdriven as compared to V-drive which is overdriven.
    Never trust pitot tube speedo's.

    Thanks everyone for your replies. This is pretty much what I expected.

    My boat will be heavy like yours Gettin' Bye, it is pretty much loaded up.

    Steve, I was thinking the same thing about those 23 pitch props. Could not figure that one out. The dealer tells me my boat will be shipped with 28's, the drives are the XZ with 1.5:1 ratio's. I will keep you posted on what it will do.

    Vagrant, just sell that Donzi BIG GUY. As long as you keep offering to drive and I get to sit in the back seat of that dully with free Crown, hell, we will always be boating together. I never had no Chauffeur before. To the lake James and mix be another crown & seven.

    Thanks guys
