      Andy and Doug I can see what your saying about the shorter strut and probably will go that way. I did notice there are 2 bushings, one is removable to grease but the other is pressed in and has a flared outside end and was wondering if you removed it before cutting, don't know if it makes much diffrence?
      Thanks again for the help

        You don't have to remove the inner bushing before you cut the stinger. I'm not sure you could without damaging it. It is either pressed in or, they used loctite, ect. to secure it.

        Good luck,
        Doug

            Rudder looks much better.

            Douggie, I like the rudder directly behind on my set ups but they are for sport. For serious racing you want that rudder on the right side. Some of my V hulls have them directly behind and they are fast....I like the balance of them turning both directions. Certainly a difference from a cat (which I mainly run) and V hulls.

            With the prop churning the water before it hits the rudder it can have effects on turning in racing conditions. I really do not think it slows the boat down as some say with prop wash hitting the rudder....in fact it may make it faster because the rudder is actually getting water already ariated (sp) so less drag. The prop has already done its job by the time it hits the rudder.

            What amazes me is to see the big 50' cats with very little rudder in the water at 150 mph...the rudder would be considered small for a boat that size but they also do not corner hard but look for top end in the straights. I saw two spin outs at the OSS nationals here and most seemed due to small rudder issues...hook or spin out and over they go.

            I also like them behind from a building issue...I have one bracket that takes care of everything...I can also offset it if I make the bracket different...kind of like the Solinger yet I always use 4 bolts. in the transom.
