As far as GPS calibration..... I ran in a radar run back in Oct and the radar was within .2 mph of what my gps read. My GPS speedo and handheld GPS both read the same.

Oh, and I think a 24 with a 500HP (470 HP) would run a consistant 80+. Maybe 82-83 on occasion.

my friend has a 79 24 with about 550hp only runs 74 it starts chine walking when he trims out its old bottom paint MOST OF IT GONE and trs drive, will a sp master 2 fit? and no hdy steering he has that drew marine stabilizer and no indicators for trim or k planes . I TELL HIM I LOOK AT MINE when I drive.

YES, 500HP MAYBE BREAK 80MPH on a 24' if it is dialed in correctly, correct prop and no hooks in the hull. (( I have found 1 props works best on my 24' 4 blade hydromotive was the best with the TRS Big Block )) Tried over 20+ props and the 4 blade hydromotive, labbed was the best !!!! GOT TOP END, MID RANGE AND STABILITY.

HI what yr and power do you have, my bud has my old mirage 25 turning 5400 about 74. does anyone know if a speed master 2 lower will fit the trs, or a nose cone for the trs if that would help him. get more speed, is there a high speed bottom paint out?

i rigged an older 24 with a 700+ hp 454, and she ran in the mid 90's 94 or so. had a 24 pitch 4 bld, but the engine turned 7000 r's.
