1983-90 Mercruiser Alpha I Gen I Outdrive Lower Unit 1.62:1 OEM 1 YEAR WTY

This Mercuiser lower unit is in good condition, gear ratio 1.62:1. From the top of the water pump, the driveshaft measures approximately 7-1/4" long and has 13 splines. Please note that this lower unit does not come with the trim tab. There are some cosmetic flaws in the paint on the lower unit, but this will not affect the overall performance of this unit, see pictures.
