    Re: 650 Wave Jammer Engine Swap and novice Freeride/ Freestyle ski

    Haha thanks guys. Yea eventually I really want to do a big bore/ ported cylinder on this. I remember hearing somewhere that Group K for some reason spent a decent amount of time working on the LX, so I think I'm going to call Harry and see what he recommends. That will be phase 2, which will be for next season. The 650 in theory with a little work should be equal to a good 701.

    Phase 1:
    stock engine with stock pipe
    Superjet 650 head
    Superjet stock carb settings
    16/19 ish impeller
    750 gph auto bilge pump
    stock ebox
    midshaft swap (650 coupler is different)
    intake grate mod
    pump rebuild

    Engine has been removed. We were going to run it memorial weekend but it somehow had a spontaneous exhaust leak. It ran fine last season. Good reason to pull the 500 and do a swap.

    32 measily hp.

    Oh also notice my ghetto fabbed flame arrestor. Another good thing about the jammer is its darn near indestructable. Even with just the screen zip tied in place, we ran the ski hard, sometimes with even up to 100lbs or so of water in it. On both my friends jammer and my own we've run them at darn near full throttle forward, sideways, and backwards continuously.

    Re: 650 Wave Jammer Engine Swap and novice Freeride/ Freestyle ski

    Ok it has been a while since I posted. The Jammer is at my brother's house in Michigan so that limits my time working on it. I'll be able to devote some this weekend and next.

    I have taken a bunch of time to clean and prep the engine. Carb is jetted correctly near as I can tell, for a 650sj. 120 pilot 115 main. The LX had a 115 115, mostly I would assume due to the lower compression head. I've also heard that the LX had a different ebox which reduced revs, I'll investigate that further later on.

    Took this time to order all sorts of parts:
    17/20 impeller for WJ/WR 650
    650 SJ head
    650 gasket kit
    pump rebuild kit
    orange fuel and primer line
    750gph auto bilge pump with switch
    some other stuff which isn't really important


    I'm now slowly working on developing graphics for skis. Here's a sneak peak of my inspiration for this build, a Blowsion LWDE ski.

    Looks Good, I believe ODD DUCK built a jammer with a 701 and a fx1 pump in it, here on pwctoday, It was dysfunctionally cool, I cant wait to see what you do with this,( No thread jack intended ) Goodluck!

    Ha. Yea her thread was one of my inspirations, so no harm posting that!

    Do you have info somewhere about her using a fx1 pump? I don't remember reading about that. I did ask her what impeller she was using. She was going to ask her husband I think and I never heard back.

    Re: 650 Wave Jammer Engine Swap and novice Freeride/ Freestyle ski

    Hull or pump? I actually have a pic with hull overall dimensions that I'm going to use for the graphics. Came straight from the repair manual.

    For those interested here is Group K's info. If they can make the LX get to almost 45 then a 100lb lighter ski with a few tweaks should be good for at least as much. And the thought of a 45mph Jammer makes me smile. Also impressive is the gains Group K lists for their sleeper mods- basically porting and cleaning up the existing parts. That really goes to show you how many losses there are on the 650. Group K goes on to say the Yamaha 650 engine has some of the most conservative port timing in the entire pwc industry... so porting yields huge gains.

    The Jammer was a way fun intro ski - it would be awesome with more power!
    "needs carb work" is a classic excuse for I don't know wtf is wrong!

    DASA powered 2009 EME Q8, 2001 XLT rescue boat, 1100 WB1 in the works.

    Big thanks to Newmiller Machine in Oregon for the great work! (Mcn6 on PWCtoday)
