    yea that's CLOSE to where u want to be... 7600 would be better.

    several things can attribute to why ur not running 7600.... 1 prop blade out of whack by even a fraction of a millimeter, high oil level, slightly worn wear ring, humidity, elevation....

    i'm a little biased to helping 03 GTX 155hp owners it was my first ski and i sold it to a guy that's on this forum (chiefwigms) ... it brought a tear to my eye when i sold that ski and saw it drive away behind someone else's car..... but i forgot all about it when i picked up my RXT a few weeks later can't beat the reliability of that machine tho (usually, lol)

    no no no... not at all. if my comment confused you, i loved that ski for that simple reason. u hit start and that ski will run forever. Damn near most bulletproof 4-stroke ski out there.

    i personally put 115 hours on mine the first season i owned it with absolutely ZERO problems... then sold it, and the new owner is on his second year with it and it still runs great approaching 200 hours

    if u stay in deep water and dont suck up rocks, u should not see any repairs on that machine.

    change the oil every 50 hours / once per season (whichever comes first) ... i might recommend i drain the coolant system and refill with fresh 50/50 mix ... fresh spark plugs... other than that, there's no maintenance to them whatsoever and very reliable.

    don't hesistate to post if u have any questions. Where are you from? u didn't post ur location in ur profile, wonderin if ur at all nearby me.

    I have a question also then... I am running the 4tec in a '04 wake eddition.. I can only manage 7200 RPMs, but i have a prop change to the Solas SR-CD-11/19, I sent a rock through the factory one and this is what it was replaced with... Id love to see 7600 on the tach. Any suggestions? It ran around 54mph on GPS, going to check it again today Im from Sandusky, Oh and ride on lake Erie.
