    Shorter would most likely hurt bottom end at the expense of a minor gain on top end ... I thought you wanted more accelleration?
    Since 1925, about 150 different racing outboards have been made.

    on a jet pump ya start out with our motors from a dead stop and just grunt the low end to get tbe boat out of the hole and plane the boat out and then crack the throttle in for the top end. all this is cut by 1/3 with the foot.

    a lot of what I know about the tuners and needing to be shorter for the low end is what I've been told by various people. the pictue I put on is the picture of what most people build and put in their boats, I've never built one so I was just kind of asking around to get an idea of how they worked or what could work better!

    Default Tuners!!!

    Rules, Rules!!!
    If everyone runs the same thing, pretty much even. Some orgs. change rules a lot when certain people win a lot.

    I sure hope you keep us apprised as thing go on since you only have one race, its only about 3 hrs for me to spectate.LOL

    oh I've already stepped out of the box from doin everything the same way, I just gotta see if it works. fed ex de-commisioned my motor last week by droppin somethin on it, just waitin on them to pay for some stuff so I can get it on the boat and really prove how bad it is. boat races are this august 4th or 7th. try gatorjetboats.com for the exact date but it's close, I'll keep ya posted on when they are. keep an eye on the jets section on thread outboard jet in progress and that's my boat bein started, you might have already saw it but we'll definatley keep ya posted an ya should come watch the race, and I'll keep tryin to think of somethin different to make it a little more interesting.
