    Not yet, but I want too. Will probably buy a extra plate before I go cutting it up. Kind of waiting to see what Chris at Pro Watercraft comes out with too.

    No complaints about the pipe. Lots of changes were made so I cant make a apples to apples comparison, but so far I like the power delivery better than the PJS 650 3 piece pipe, the 750 limited, and SXR wet pipe. The power is just always there and there is never a lack of it or hesitation.

    I'm interested in the Pro Watercraft version too. I have both of the plates from Rhaas plus the pre-production version, no complaints about any of them but a skegged plate could be really cool.
    Never argue with an idiot, they will drag you down to their level then beat you with experience.

    Nice ride report. That pole is the bomb. When are we going to get all the Michigan conversions together for a ride.

    Re: New Project, JS Conversion freeride ski

    Overall it was a good weekend riding the conversion ski. Now that the initial joy just being able to ride it has worn off, so does the rose tinted glasses.

    -The Hull: The hull overall feels good. No longer feels like a JS hull as the other conversion ski I rode still does. Wish the front sponsons were bigger as the rocker has made it more difficult to rail a corner. Love the rocker though, and its going to be great in Lake Michigan waves, only issue is that without the front lip, all of the water displaced when the nose its the water goes into your face. I will live with that. Pump feels good, no cavitation, but I have too much pull and going over small boat wake and stuff when wide open the pump unloads a little. Needs a scoop grate at a minimum and ultimately a pump stuffer. Would also like to pitch the impeller a little lower, its at 14/18 right now, would like to see a 12/16. Hull handles the speed very well though, much better than I was expecting. I am going to start experimenting with rideplate mods and trimming the nozzle up a little. The ski overall jumped pretty flat.

    -Motor: Overall snappy, has much better bottom than I was expecting. Top end is lacking. No GPS numbers but we guesstimate upper 40s-50. Not bad by any means, and honestly this doesnt need to be faster. I think there are several things contributing to this that each are taking away 1-2mph. I will fix some of those things and leave others. Pipe is cool and wet, I may dry the pipe out a little more, but not a lot. I remembered on the Advent, I am running the SXI 10 curve which is the weakest of my curve set, and possible the weakest of all. This I will be fixing soon. Carbs still need more tuning, still too rich. This is on going and will be fixed. And, water injection settings could probably be tweaked a bit. Overall the ski is solid and a joy to ride, but there is room for improvement.

    Not a super big update, but did a little work. Pulled the ebox and cranked the timing up a bit to curve SXI22, also re-adjusted the revlimit, and water settings. Reinstalling the ebox was a paint, but not as bad as I thought it would be, just had to pull the headpipe. Also installed a limiting rope and some Kahuna hood latches. I will probably put a pump wedge in to trim the nozzle up a couple degrees before we go ride some Lake Michigan waves on Sunday.

    Re: New Project, JS Conversion freeride ski

    Nice progress. One thing to consider is what BLRider and I are running into. We found that going steeper on the impeller pitch actually gave us more low end. With my ski, it was so under pitched that the lower impellers would just cause a smoother delivery of power, like I have said before. When I increased the pitch and then reduced the nozzle size from 80 to 76, there was actually a big improvement in low end. I think these big engines require a bit more finesse on setting up with the right pitch. Anyway keep up the good work, this is a beast of a ski.

    Re: New Project, JS Conversion freeride ski

    I was planning on bringing my nozzle down from 82 to 80 and see how it feels. I feel my impeller is decently steep, hooker 14/18 and was actually thinking of taking it down to 12/18 but that would probably be one of the last adjustments I would do.

    Re: New Project, JS Conversion freeride ski

    New update. Got some new graphics put on the hull and had a few more Lake Michigan runs and the motor runs perfect. I dropped the nozzle size down to 80mm and that seemed to help a lot but the pump could really use a stuffer. I went to JetBlast with it in the Wisconsin Dells and probably around 20 people rode it and everyone loved it and came back with a smile on their face. Also had a offer to trade for a RN SJ on the spot. Total loss is doing well too. I figure it will get 4 tanks of gas before the battery needs to be recharged. Then disaster struck. I was riding surf in Lake Michigan last week. Launched off a wave and did a 180. When I landed I heard a big crack and then rode back to shore. The crack was the whole front end of the ski getting torn off. It was cracked about 1/2 the way around. Never showed any type of stress before but I guess the torque of the 180 was too much for it. Not sure what I am going to do at this point. Its definitely fixable but I am burnt out on jetski projects and have a massive list of other projects that need to get done. I may sell off the motor, exhaust, and intake and hang the hull on the wall. Ive been having a blast riding a stock 440 so I may look into getting a mint stock 550sx. We will see. Going to pull the motor and tank and see if there is any other damage anywhere and decide.
