    GPS'd my GTX

    Got a marine gps last fall and finally got a chance to use it on my 97 GTX with about 160 hours on the 787. 52.8 mph yesterday with just under a full tank @ 6800 rpms. Ol' girl runs like a champ and still performs as she should.

    Not bad. What's the max rpms on those?

    Pretty much right about there from everything I've seen on a stock motor. It was really like 6740 but I rounded up.

    does a pump wedge make that much of a difference? when you get a wedge you need a longer driveshaft right?

    The same day as that GTX speed run i pulled a [email protected] 6950 on a 96xp with only worx intake grate and proK filters/jetted carbs.
