Topic: Adjustment on Merc-O-Matic - more power

  Last April, I had an issue regarding the Merc-O-Matic and its hard shifting going from 2nd to 3rd. The resolution was to lengthen the throttle linkage on the side of the transmission. As I proceeded to lengthen the linkage, the shift point from 2nd to 3rd became higher, the kick down engages with less throttle and the torque from 30 mph to 50 mph increased dramatically. It almost seems like the transmission was fighting the engine. Is it possible that the transmission was holding the engine back? After the adjsutment to the linkage, when the transmission has shifted from 2nd to 3rd and then when I allow the speed to drop down to 30 mph with it still in 3rd, there is allot more power and faster acceleration (low end torque) when accelerating from 30 mph to 50 mph+.

  The answer is, shorten the throttle linkage rod, by turning in adjuster “U” bracket on the top of the rod, down until the issue is resolved. This will take a few adjustments and test drives until you are successful. The rod is located on the driver’s side of the transmission and connects to the throttle linkage behind the oil filter housing.
