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

This lower unit was removed from a showroom outboard- the customer who purchased the outboard converted their motor to a Jet Pump- this lower unit has 0 hours of use, it has never been run. The lower unit does have some shelf wear from sitting around in a shop environment for a while- the worst of which is a lite scratch along the side. 

The original water pump assembly was removed and installed onto the customer's Jet Pump so we installed a new water pump onto the lower unit- the pump housing and wear plate are aftermarket but the impeller itself is an OEM Yamaha impeller! 

This lower unit is for 20" transoms, the driveshaft has 20 splines and measures ~19 1/8" 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%

If you are unsure of fitment, send us your model info and we will assist you.
