    Your ski is running well for those mods. The Gpr is a good efficient hull for top speed...hard to beat for the money. I'd like to get another one myself. I've been away from ski's for several...

    That's probably about right. Is that with the trim all the way up? There are not really any parts on the ski to improve speed at this point besides the 14/20 prop. If you were to remove the air box,...

    I understand. To really get to 75mph or more a ported 1300 top end would be the way to go. While that speed with a 1200 is possible it would be a smooth water setup in perfect conditions with all...

    It was used on my ported 1200 single pipe and my 1390 single for top speed. Both used '05+ pump.
