I have a 1994 Force 120 with that the previous owner ran with out a thrust washer which wore off the lip on the lower unit that seals around the prop. Therefore the exhaust exits in front of the prop which causes cavitation and I don't go anywhere. The serial # on my motor is 0E041429. I found a lower unit with # 1208F91A. Could I use this lower unit with my gears installed in it. I think my lower unit is a type D from what I have found out. Any advice or info about where I might find this info would be greatly appreciated. Thanks. Jim.
