Old Part Number: 421-150, 2-300-150, 2-300-155, 92-300-150
Fits all Minn Kota freshwater motors with 112 pounds of thrust from 2014 - 2018 and many models from 2019.
Anytime a lower unit is reassembled, the thru bolts need to be tightened to 40 - 50 inch pounds for 4-1/2" diameter lower units.
In June of 2019, the 112 pound lower units went through a design change. Minn Kota removed the timing key on the Center Housing and the mating Brush End Housing. (The key was there to help prevent the skag from being rotated and affecting the motor timing.) The new design better positions the O-ring against the shoulder of the Brush End Housing. If your motor is from 2019, you will need to check for the presence of the key slot in your Brush End Housing.
If your brush end housing HAS this key slot, this is the CORRECT p/n for your motor. If your motor does not have this key slot, you will need p/n 92-300-175.
This part will come with the prop shaft seals and flange bearing already installed.
