well nice Twin phil. thats a very old Twin very similar to what i had when i 1st started running Twins its probably over 15 years old but still a good running boat.. heres a few things i would do;
1)Update the boom tubes those ones will work but we use smaller tubes
2) replace your pushrod seal with the Aeromarine ones
3) Run a rudder from speedmaster with only 1 water pickup
4) Replace your struts and use extended struts also offered by speedmaster hardware
5) presure test your tanks or get another set from walt barney give him the measurements of the current ones you have
6) Get a Updated cowling from Ralph Almirola provides better down force and aerodynamics
7) Steering servo Hitec 5755MG will be perfect
8) have a Bell Crank set up for throttles using only 1 servo
9) Have working 3rd Ch using another Bell Crank similar to the throttle servos
10) BVM needle valves are the best for our application
11) I would talk to Ralph Almirola to see if he has the time to talk you on the phone to get the boat Tabled to the proper specs or send him the Twin and have him do it for you if he has the time..

12) If you are planning on keeping the Twin and racing it i would suggest extra boom tubes,cowling and Front sponsons.
13) ******Email Ralph *******
thats what i would do. Alot of people will tell you something different but from my personal experience I tried to do everything myself and it was all over the place and i was fighting the Twin left and right and followed other peoples advice. i went strait to ralph the builder of our Twins and we did everything listed above before it even went in the water.. Hes the best at what he does.. never had a problem since then..
cant give you the measurements because its a old Twin and we are 6 to 7 generations ahead of that twin it will run good trust me if you follow the right advice..
