Evinrude Johnson 40 48 50 HP 1989-1992 Lower Unit Gear Case 20" 435277
This is a good working lower unit. The oil was clean when drained and passed the pressure test (15 psi for 20 minutes).
Skeg has a slight bend but this is cosmetic only and will not affect performance.
The driveshaft has 14 splines and is about 22" (from the top of the gear housing to the end of the driveshaft).
The prop shaft has 13 splines.
Shifts smoothly and stays in gear as it should.
The water pump was not inspected but we suggest replacing impeller before use.
You will need to re-fill with new gear oil prior to use.
