    20' set back?

    New to me boat, 20' xdc 225 sport xs with a 10" bobs hydro plate, Im running 431 wet cells and adding a 12 talon my question is should I add 4 spacers or am I better at 10" since im ass heavy now? What gains would I see? I have a bravo 1 xs and it ran 80.8 solo loaded. Would I gain any mph, much more backwash, much effect on holeshot?

    With the Talon I would stay at 10" . How high are you running the motor, prop to pad? Prop pitch?

    Hydraulic plate, running a 28 Bravo xs. I have not added the Talon yet but was thinking with that, the 3.0 and 4 batteries that 10" might be good but I never tried 14" set back so ?

    Same motor for me on a 20xd. Sportscaster and 1.62 no way I could turn 28
    I don't believe. Will be a lot of weight.14 inch for me.

    I have a 1.62 sporty as well, the 28 Bravo xs runs like a typical 26 they are not pitched stiff at all. It turned 5950 with 3/4 gas solo

    What prop are you running? How is holeshot, topend? Do you run with a drag plate?

    With that much weight in the back I believe I'd stay with 10" 12 at the most. 14" plates work better with the 2.5 motors. Just my OP.

    I had a 225 sport and 1.62s at one time. I ran a 14” plate with no issues at 1.5 above. 27 Hydro/27 Bravo 1 also ran a Razor

    Best i have seen is a 83ish loaded and solo with a 26 hydro.
    Hole shot good i rarely fill live well so no help there. Does have a allison plate previous owner said did not handle well with out it.

    Thx, thats what I was thinking as well but was looking for opinions since I have not played with set back on a Bullet. It handles good now and has bow lift just wondered if I would gain anything. I added 4" spacers to a 9" plate on my xb2003 and saw no benefit, it wasnt as heavy in the back as this though.

    Did you always have the 14" plate right? I think I will put the Talon on and get some run time and see how it handles with the 31 wet cells and gas/livewell etc.

    Always 14” on my boat....not saying it’s the best. It worked great either with a 225 and with the 250.

    I'm betting the 4 group 31 batteries weigh 280 lbs or better. I don't know how much a talon and the rigging g weighs. I ran a 12 inch plate on my 20 XD with a 225 pro xs 3ltr. and 300 xs 3ltr. Empty boat a 14 would have been ok but with a full tournament load and fuel and water in the wells I don't think 14inchs would be any benefit

    I have a 20xdc, when I had my 280 I was running a 14" manual set back. But no power poles and only a 24 volt system. It done very well. I've since added (2) 10' power poles, went 36 volt troller (but went with (1) 36v lithium ion battery). Also among all these changes I went with a 250R. I had issue blowing out getting on plane, so I switched to a 12" manual set back, worked pretty well, but decided to go with hydraulic jack plate, thinking more has to be better, I went with a 14" Bobs hydraulic, and the 14" is just too much for my set up, wishing I would of went 12" possibly even a 10". I wouldn't recommend over a 12" if your carrying much of a load in the 20'er.

    Thx that is exactly the kind of info I was looking for. I have a 10" hydro plate now so was inquiring if I should add 4" spacers. I have only ran the boat twice but it seemed to be a good setup with the 10". I will be adding a talon as well so based on your out come looks like the 10" is good, I wouldnt expect going to 12" would offer much tangible benefit either.

    I wouldn't waste the time or money going from the 10" to a 12", I honestly think the 10" is going to give you the best hole shot and still run out very good on top. The 20'ers are less forgiving on weight than the 21's. There seems to be a very defined breaking point on the 20'ers when too much offset combined with too much weight goes from getting on plane to an absolute nightmare dogging out of the hole. Thats where I'm at now.

    I really think you are in a good spot with the 10", gives you room to add a little weight such as the talon.

    Thx, my last post was in response to your earlier one. I agree with you 100%

    I had 10" 12" and 14" of setback on my 20xd/300XS, The more setback i put the slower my holeshot was, Every 2" i gained 1mph on topend. BUT with a 2 deg negative trim wedge and a hydrofoil i gained all my holeshot back.

    14" of setback, no foil, no negative trim wedge



    Same setback but with negative trim wedge and hydrofoil

    Massive difference! I may run a foil, need to tweak prop plugs to see where im at 1st. I ran a foil on another boat and liked it but didnt care for the way it pushed the nose down running slow in really rough water
