***Brush End O Ring Special Note:
- This kit includes two different o-rings for the brush end housing. These are the two largest diameter o-rings in the kit. Use the o-ring that is the same as the one being replaced, the motor will not seal if the incorrect o-ring is used.
- Part number 701-107 is the smaller of the two o-rings and was the original design. To upgrade to the new design you will need to replace your Brush End Housing (for freshwater motors, 92-300-155 / for saltwater motors, 92-300-156).
- Part number 701-103 is the larger of the two o-rings and was used after the design change in June of 2015.
- The design change was to make reassembly easier, the deeper groove in the brush end housing keeps the larger o-ring in place with less effort while the motor is disassembled. Once assembled both designs function properly. When assembling a lower unit that uses the 701-107 o-ring applying a small amount of white lithium grease in the o-ring groove helps keep the o-ring in place until assembly is complete.
Anytime a lower unit is reassembled, the thru bolts need to be tightened within 40 - 50 inch pounds for 4-1/2" diameter lower units.
