1984-1993 Yamaha 20" Lower Unit PRO 40 50 HP 3 cylinder 1 YEAR WARRANTY!

As seen in the pictures, this does not come with the trim tab. If you look in the pictures you will see some corrosion and pitting on the side of the housing and when looking down into the unit, but this is very common with used lower unit and it will not affect the overall performance of the lower unit. Please note that we have taken the time to strip and prime this lower unit, so it is ready for a new fresh coat of paint.  The intake screens are in great shape and are not cracked or damaged. Because of shipping restrictions, we are not allowed to ship our lower units with oil in them. Please add oil prior to use. This will make a great replacement part for your outboard! Purchase with confidence!

Driveshaft Length (top of water pump to end): 19-3/8"
