I haven't found the bushings yet, sorry.
I did get a few test runs in guys. Had very good and some bad results! ,.. As expected, at least initially, This boat has VERY VERY good turning attributes. I was a little worried that the boat being hard to launch with the more narrow ski,.. but not to worry.. Launched SUPER easy. This boat weighs right about 3.5 lbs. I ran the boat with the set up exactly as designed with no tweeks. It was a bit windy, this chop would would have given the last some hop issues. Not this time. When in the chop the front of the boat hung a little higher, the prop stayed planted. I am very please. I narrowed the ski 15% and also shortened it 3/8 in. THis seems to have done exactly what I intended it to do. I was running the NR 5p with a aftermarket head button built to specs supplied by CHris Woods. Though I didn't have enough time to try more props or adjust the pipe, the motor with more compression showed great promise... tougher idle,.. but this mod seems to really have potential.. and not a real expensive option. IT was chilly and the retrieve boat was full of water,.. I really didn't want to drain it and use it... so,.. being afraid to die in the water I came in a little fast,.. then I noticed a cinder block on the half submerged when I was coming in... well,.. too late,.. hit the cinder block, not too bad though.. just broke 2 boom tubes and didn't even scratch the paint!!! So at least initially this design seems to be an improvement over the current design. The speed was as the usual JAE type, less tail hop and incredible turning. I'm ordering the boom tubes now.. should have a few good weather days this week,, I'm going to try and get some video for you guys then,.. I encourage other builders to try this boom tube / turn fin concept... On initial testing it works extremely well...
