OK last year I had Duane at HTP machine my intake and install a ride plate and shoe. Ever since this was done when I hit the throttle at a very slow speed under 13 mph the engine races and the boat will accellerate. I must be moving before I can snap the throttle and go. It never did this before the ride plate and shoe was installed, It would just jump up and go. Nothing else was done to the intake or jet. Same loader I had before. What gives????
I have a 1979 Bahner with a delta pad.
