    Default engine/jet set back questions

    Ok since im new to the jet boat world and have no clue as to how this hull should ride (i grew up on vdrive flatbottoms) and I just cant seems to ever leave a boat as is I have a few questions.
    In the vdrive world generally setting the motor a bit more forward in the hull seemed to have good results. Where do you want a jet boat motor to sit?
    This motor seems to be pretty far forward, Im toying with the idea of setting the jet back as my "winter" project later this year. Im curious about setting the motor back as well. Good idea bad idea?
    I am planning on a place diverter, this boat feels like its hugging the water too much, like a vdrive with the plates way down or an I/O all the way down. Since I have already blown my boat budget for this summer and cant afford a diverter and a 2 piece bowl for a droop snoot I am wondering if a wedge would be worth a try. Also is this considered a heavy hull or a lighter hull? 19' tahiti with 455 olds
    Any thoughts?

    Dont know anything about the set back thing, but you defininetly need a place diverter! It makes all the difference in the world on heavy boats! I have a Heavy 21 footer myself and when i start to trim up the place diverter its like an anchor gets lifted up and the boat picks up mph and rides better! A place diverter will bolt right up to your JC bowl.

    A place diverter will help. But moving the pump back is a iffy thing. depends on horsepower and pump setup. Spend more time researching it. Or ask Jack @MPD, he'll know the answers or where to head.

    You cant use a wedge with that bowl. That looks like a mini daycruiser and a heavy hull.

    A split bowl and diverter would be a good upgrade with possibly a droop. I don't think moving the pump back is going to get you much bang for the buck and a lot of hard work. Not sure if a shoe and ride plate would do much either, someone will chime in.

    X's many , Hands down The best Bang for Buck would be a Place diverter trim , it will help free up the boat (reduce wetted surface) and allow you to plane the boat quicker,adjusting for load and attitude , wouldn't recommend a droop, wouldn't set the jet back , if it became neccesary to pull the intake (if it was leaking for example) it would be prudent to machine and install a ride plate at that time Otherwize crank up the tunes ,drive it and have fun Tom

    Always a good idea to talk to someone with the same hull before doing the setback. Can open a can of worms when trying to get the boat back on the water as it may not like the "set up". One added benefit of the setback is you can put the hand hole outside the boat, if you boat in parker, thats huge.

    parker is a little far for me...lol, but i will be boating on the snake river as soon as this winter/RAIN RAIN crap will stop. The only reason i was thinking of the set back with the pump and the motor is because I will be pulling the motor and pump this wither to repaint the hull. I just figured if its out and Im doing some glass work etc. if i was ever going to do the set back it would be the best time to do it.
