For sale is a HIGH-THRUST lower unit for a 2010-2018 Yamaha 50-60 hp outboard, applications below. This lower unit is in good working condition. It turns over smoothly and shifts correctly. The gear lube was clean when we checked it, no water and no metal. This lower unit did hold pressure too. The water pump impeller is in good condition. There is a slight bend in the skeg and some other minor cosmetic flaws. Other than that, this lower unit shows well and is a nice replacement unit. 

NOTE: This lower unit was removed from a HI-THRUST model, be advised! 

The driveshaft on this lower unit has 16 splines and measures ~19 1/4" from the top of the water pump housing to the top of the driveshaft- this is for 20" transom motors. The prop shaft has 13 splines. See pics.
