nice job.boat looks great.you are right about finding parts for these boats,getting scarce and expensive.i have 2 Fastech nitro's that im running,and im not running them too hard..lol

Thanks for the compliment.

I do fear I have really messed up the handling of it though. It's very unstable at high speeds. The entire hull wobbles left and right the faster I go. It is also very jumpy in faster turns.

arriving late to this thread, guess I should have posted up my pictures last fall when I converted mine over to dual rudder. probably could have helped...oops. funny you mentioned the replacement rudder not matching. I actually modified the new one to match the original which If memory serves me correctly meant I shortened it a good 3/4" or so. the cooling pickup is a lot better on the new one(pick ups on both sides) but I wonder if the extra length is causing your hull wobble? shooting in the dark as I'm no hydraulics expert. other then that I'm running the same setup you are including the prop, it does have a little bit of chinewalk but nothing that gets it too out of control.
p.s. assuming you through bolted the rudder bracket make sure you have oversized washers. I cheaped out and used ones way to small...caught a rock and it pulled bolts right through the transom.. nothing a little glass couldn't fix but could have been avoided.
