    JP, how deep is your strut?
    What you say may be true, but my setup works for me with Thr advise I gave and I have Jo bounce and no speed lost through turns at WOT. So, tomatoe, tomato.

      Whether you notice or not, you are losing speed in the turns. Ask anyone who races cats if they run a inline strudder.

        Jack, it is impossible for you to not lose speed in a turn with the inline setup... The rudder is in direct interference with the natural cone of the prop. Whether or not it's a big difference is the issue but I can guarantee you you'll losing some speed.. hence why the larger counterparts typically have dual rudders or engines on the outside of the rudder... its not only more stability, its to maintain the speed through a course.

          I noticed a HUGE difference while cornering during races when I went to the offset rudder. Running the boat by myself, I never realized how much it was actually slowing until I started racing it. I was blown away how much it slowed down. I did find, and posted somewhere... I think in the race set up thread, that offsetting it has nothing to do w/ getting rid of the bounce. Its all about finding the trim and balance. JackB already said that. Anyway, If I wasnt racing, I probably would have kept it inline just because I prefer the look.

            I wounder why I tuned my boat (or tried too) about 20 runs and never got the bounce out and then when I installed the kinetic offset bracket it instantly went away? Maybe its just me but I cant understand it when people say the bracket has noting to do with it because in my case it had a major difference..
            Heck Ive even tried to tune it to bounce and I cant with the bracket on..

              Filled in my rudder inlet since it's not used now.


              Also took the rudder brace off and finished it up. Made an epoxy block on the inside of the transom where it mounts so it's more securely attached and solid to the boat/hull. Before I was pressed for time wanting to go run again I used an aluminum brace I cut and made. But wasn't 100% happy with how it held. Also sealed the bracket to the hull with rtv as I mounted it. Instead of the thin rubber pad I was going to use.

                Still too windy here. It's nice weather sunny and warm. Just windy really bad. Maybe I need a sail boat.

                  Agreed, Scott. I never said mving the strut didn't work. I just said it wouldn't take the bounce away. If I were racing my boat I would look in to moving it but I don't personally like the way it looks. Loosing 1-2mph through a turn doesn't mean anything to me since I'm sport boating with friends. 1/2 the time one of u flips over anyways since were all obeyed powered!

                  So again, for me, my setup works just fine :)

                      I've got 4 with the girl and flags being made up(see last post with it superimposed on my boat) to see how it's going to go. They were supposed to be done today but they haven't finished them yet. I might get them Thursday or Friday.

                        Got to run a little today after work. The offset rudder helps a bunch. I still need to play with the setup to keep the boat on the water. I have the COG way forward like 12" and the strut level all around. Still can't hold throttle down or she will blow over. I was able to get her up to 59.8 MPH today tho. Still has more than that locked away. Might try a hair negative strut angle or make a clear lexan air dam. Just kicking ideas around for now.

                          perhaps some lead weights in the front.

                            where is the strut set at? tiegman is running his level and touching the top of the table when boat is sitting on table......may have to shave the cornner off the strut brace with a big prop

                              My props won't ever hit the strut brace now. I've cut some length off it since I made a new offset rudder mount.
                              Might be able to see how much I cut off in this pic. the two bolts on the back of the brace have been relocated I drilled those holes out for them to mount there.



                              I have the strut dead level with the bottom of the hull. Center of prop shaft is at same level as bottom of ride pads. The angle is set at 0.

                                Went ahead and glassed in the windshield too. It ended up being the weak spot like I feared. It got a very small crack in it the other day. So hopefully this saves it from getting worse.
