    Reverse Gates Position Problem (Pictures Included)

    First of all I want to introduce myself. My name is George and I'm new to the forum. I have a '97 Sea Doo Challenger 1800 with twin 787 Rotax 110 hp.
    I hope this is not a silly question but here we go...
    When I put the lever in Forward position, it seems to me that the reverse gates are still covering about 15-20% of the jets. However, if I move them up by hand to what would be the correct position (to me, as least) it seems like they lock and I can't move them back down with the lever, only by hand again.
    Here are some pictures that might help understand my situation.

    Is my forward position normal or should it go all the way up as it does when I move it by hand? If it is not normal, how can I fix this?
    I hope I was clear enough presenting the information.
    Any input will be greatly appreciated! Thank you

    looks like your cable may be out of adjustment. check under the lever or where the two meet back by the engines. if not you can always do the bucket trim like all the Doo 4 strokers do.

    Thank you for your input!

    So you still think that the reverse gates should go all the way up as shown in the last picture? I read about "bucket trims" in the forum but they are mostly for jet skis and people are saying they probably gain 1 mph for top speed. This is the least of my concerns since I usually run the boat between 5000-5500 rpm and probably ran it up to 6000 rpm twice since I had it (three years).

    What I will do tomorrow is accelerate to 5k and see how quick it gets up to speed and see what kind of mph I'm running at those rpms. Then, I'll slow down, turn the engines off, get down and move the reverse gates up by hand (fully opened) and do the same test. If there's a noticeable difference, I'll look into modifying the setup, if not, I'll leave it alone.

    I'm still curious to see if anybody else experienced this. Any input is helpful!

    Actually, I took your idea and trimmed the reverse gates with the help of a drill and a small saw. I'll post some pictures during the week. Hopefully the weather will be nice and I'll be able to test it out, too.

    Oh boy I wish I saw this. When you pushed up on the buckets, did they lock in all the way up? then you were only able to bring them down by flicking the small lever on the starboard side bucket correct? This is the proper way that these work. If not your cable was out of adjustment or stretching to the point that its ready to break. You should not in anyway have to trim these buckets.
