Mercury 20” Lower Unit 4-Stroke 4-Cylinder
Mercury 20” 4-Stroke 4-Cylinder lower unit for 1999–2006 outboards, 75 90 115 HP. Inspected, serviced, and tested for proper function. Gears are replaced only if bad — good OEM gears are retained. Please note: There are scuffs and scratches in the paint, but nothing that will affect performance and is very common in lower units. This does not come with the trim tab, but the one from your current lower unit can be used. We have taken the time to add a new skeggard to the bottom of this lower unit, which is a $100 added value by itself.
