    Adding Hydraulic JP to 919

    I currently have a manual and I am still learning but has anyone gone from a manual to hydraulic on the 919?

    Has it made a noticeable difference in top end performance in reference to minimizing chinewalk?

    I am getting better but currently max out at 5600@ 71 before I back out due to chinewalk.

    A hydraulic plate won't increase top end performance. It will however give you the ability to adjust on the fly for changing conditions.

    I know you ask about a 919 but I have a 721 and I installed a 12 inch bobs and it was night and day difference almost no chine walk now, most seem to agree to go with a 12 inch that's what I was told when I got mine and from the 10 inch fixed plate that came on it there is no comparison

    the plate wont fix that chinewalk, it will give you the option to adjust but you will still walk until you learn how to correct the boat at those speeds, practice makes perfect. It will be worth the install but don't expect it to totally eliminate the walk. A lower mounted plate will walk "harder" than a higher mounted plate so coming up with it should help but eventually you get too high and lose performance. Typically you don't really know if the plate is set right until you reach wide open throttle and start adjusting from there, I can kind of tell when im in the 60 mph range but I really tend to get dialed into a boat once I hit the 72-75 mph range and start tweaking it there once it pops up on pad. Honestly you probably haven't even felt it really take off yet only seeing 71mph as that's probably just about where the 919 starts to really get up and fly. My advice is get back to that 65-68mph range and try and hold it there with the hot foot pinned to the floor but your trim down. Then slightly bump the trim up a touch and repeat until the boat gets out of control, then trim down and start again, its like unlocking different levels of the walk, it starts out easier to control, once you control that bump up and learn that next level. Use the wheel and you will be making slight left hand turns only from say noon to 10 or 11 oclock and back to correct the walk.

    Ok sounds like more seat time is required. I am starting to hit the 68 mph range with out a lot of issues.
    I talked to a couple of guys on water that said 70 is reasonable but after that things do get hairy.

    It takes a lot of practice. I remember my motor had like 20 hours on it before I really figured out how to drive it. But once I started figuring out how to control the walk I caught on super fast. I’m sure others will say the same.

    I have 919phx same motor and prop that you have. I was having your exact problem, had atlas 10 in installed it helps a good bit also i think one of my biggest problems was we have small lakes in ohio so i was running around with no more than half a tank of gas or less every since i bought the boat so one day decided to fill it up huge difference in the chine walk i could barley hit 68 without it going crazy now i keep it pretty full hit 73 easy with a tad bit of walk don't know if that will help but seem to help mine a lot GOOD LUCK
