For sale is the lower unit assembly for 2015-2018 Yamaha 75-115 hp 4-stroke outboards, this may fit other years too.

This lower unit does not have much use on it. The customer had purchased the motor that this gear box was removed from brand new and used it for a part of a season before replacing this lower unit with a Jet Pump. 

All that said, this lower unit is excellent condition, it has only seen freshwater use. Mechanically, it turns over extremely smooth and appropriately. The gear case shifts properly. The seals are nearly brand new-we did pressure test them just to be sure and they passed the pressure test. The water pump impeller is brand new. Cosmetically, there are signs of use(light scratches, scuffs, etc.) but overall this lower unit shows extremely well. 

This lower unit is for 20" transoms, the driveshaft has 20 splines and measures ~19 3/16" from the top of the water pump to the top of the driveshaft. The prop shaft has 15 splines. See pics. 

NOTE: 

This is an OEM Yamaha lower unit, it is of much higher quality than any cheap aftermarket lower unit you are going to find for your Yamaha outboard. 

Returns are accepted within 30 days but we do charge a restocking fee of 20%
