Early 1990's Nissan Outboard 40 HP Lower Unit Gearcase
I'm not sure what models this will all fit - compare the information below before purchasing.
Oil was clean when drained and passed the pressure test 15 PSI - 20 minutes.
The driveshaft is 21 1/8" from top of gear housing to end of the driveshaft. The driveshaft has 15 splines.
The prop shaft has 13 splines.
The water pump impeller was not inspected and should be replaced before use.
