We had JC cone a sm years ago and it was awesome, he added about 6" or so to it and it was by far the best handling lower unit I have ever driven. Ended up breaking the skeg on it and JC talked us into a TM. TM are great lower units but we lost 3mph and the handling was not as good. And yes JC is the master at building lower units, he has been building them we'll over 30 years. I'm sure Todd does a great job too he always has fast boats with special secret mods to his lower units that only he knows.
