    On anything with over stock horsepower/speed, they increase the chance of a broken gimbal

    I have one will sell cheap, but yes they put strain on the gimbal and bellhousing assembly. They do add MPH though!

    I had one on a Checkmate 230 Enforcer with a 600 hp 516" a few years ago...
    Here is a copy of my review of it....
    BTW I would NOT run one in a "performance" application without dual external steering.

    I got the Stern Jack installed and put about 150 miles on my boat in the last two days...

    Soooo the BIG news everyone is waiting for, did it pick up any speed??

    ........nope... ...

    With this prop I ran 81 mph at 5250 in the past...

    Today I had about 1/2 a tank of gas and I think the temps were in the mid 90's or so, and it ran 81.7 at about 5350 but I was WAY over-trimmed to get there....

    Now the GOOD news...

    It handles like a COMPLETELY different boat.....

    It gets out of the hole WAY better..
    The trim has WAY more control on the boat than before.. :smoke:

    At WFO the "chine walking" is almost non-existant..


    When I was out last weekend, running in the mid 50's I had the tabs buried almost the whole time and the drive was trimmed almost all the way down, just so the boat was riding pretty much level with the water breaking right behind the windshield. when a larger wave would come up it would still send the bow skyward...

    This past weekend, the water conditions were about the same but I was able to run with a little less tab and a little more trim, I was still ending up airborn on the bigger waves but it at least it was flying "level" which I don't mind at all, nor did my passengers..




    So all in all I am REALLY happy with it, and will leave it on... I was hoping for some magical speed but it just didn't happen. I can't really say I'm disappointed in it either... My boat now handles GREAT!!!!

    ..next I need to get some bigger trim tabs.... then hopefully another labbed prop

    I know this is an old post but do you still have that stern jack for sale? I am looking for one or imco makes one as well, and I wanted to try this instead of an extension box.
