    How much speed does a full tank scrub on a GPR?

    Hi all,

    Just wondering how much speed a full tank scrubs off of the GPR? I'm thinking it could take a 1 or 2 mph....anybody got rough ideas?

    Thanks!
    Steve

    I would say around 2-3 mph depending on the conditions.

    your pretty close on your first guess, and it will always vary a little depending on the setup and conditions too.

    There are many out there that actually achieve their best top end numbers with about 1/2 tank vs. 1/4 of a tank. It's not just a weight game, but its a "balancing" game too. So you could actually have more weight in the ski to be pushed and actually be faster, rather than a "lighter" unbalanced ski.

    Food for thought.

    I have found that with my ski... at 3/4 to 1/2 mine seems to balance best with me in the center on the sled. as I get closer to one bar: I have to lean over the handle bars on hole shot... and work my way to the back of the ski as it starts to plane out.
    I may be me and my ski are retarded but that's what makes it drag the best.

    Yep, I see my best speeds at 1/2 tank. Point of diminshing returns.

    My 18 gallon tank can scrub 2-3 easily when full...but it's about the same once it gets half. I really don't see much difference at 1/4 tank and lower. The jetskisolutions.com tank pickups are great.

    same here, just a little less than half around the 3/8 full mark.
