Agree 100%. Hated my ProTec. Boat never really ran right and finally it started limiting to 2k RPMs in limp home mode. Best and only mods/repairs done on my boat were replacing the pro tec with the SKIDIM Mallory distributor retrofit kit and replacing the Holley 4010 carb with a 80319 model Holley 4160. It purrs like a kitten now. Aside from rough idle at initial start when cold, you'd be hard pressed to tell the boat isn't EFI.
