Old Part Number(s): 431-304, 2-200-304
Fits all Minn Kota 65# thrust and 70# thrust salt water motors.
This center housing measures 6-3/4" in length and 3-5/8" in diameter
Please not the picture with the highlighted area. This small notch should line up with the skag of the lower unit. If the center housing is installed upside down the prop will spin backwards.
Anytime a lower unit is reassembled, the thru bolts need to be tightened to 35 - 45 inch pounds for 3-5/8" diameter lower units.
