    21ft Bullet Guys...Your Jackplate hight survey ??

    Reading another post (and not wanting to hijack it) I got to wondering where guys are running their jackplates on 21footers.

    I had always thought on a bullet the higher you could get your jackplate and keep water psi the more speed you would get.

    So I am interested to hear your 21footer combs:

    Jackplate hight ~ Motor~ Gear Casse~ Prop ~ Speed ~ Rpms


    Maybe it will help others too

    I'm running a Atlas Hydro plate and run anywhere from even to 1 1/2 above depending on load with a 250 proxs with mods and a sportmaster 1.62 gears, I just put the 300x on and have not ran it but once.

    With anything less than a 300 you need the TM case to make the 21 run. I am currently running 1/4 above but have had it at 1/2.

    Most are between 1/2 below and even.

    I will miss you my dear friend.

    LOL And from what I see you post it looks like they may be working out for you. I think when you and I both started I mentioned a 28 bravo being a strong runner for a fishin wheel

    1/2- 1 1/2 below with my HPDI LU. I only have 12 in setback. This depends on the load I have and what prop I run.

    Re: 21ft Bullet Guys...Your Jackplate hight survey ?? (2500)

    250XS 10" hydraulic plate

    When it's nice and I can air it out -- even with the pad give or take a 1/2"

    Most of the time, it's burried to improve rough water handling.

    Running across the flats, it's jacked up to the max.

    I don't think I could survive the waters I fish withou a hydraulic plate.
