1999-06 Mercury 25” XL Lower Unit 75 90 115 HP 4-Stroke 4-Cyl 2.33 1 YEAR WTY!

This lower unit is in excellent condition. We have taken the time to professionally inspect this lower unit. The skeg on this lower unit is in great shape. From the top of the water pump the driveshaft measures approximately 26" long. There are 18 splines on the top of the driveshaft and 15 on the propeller shaft. The shift rod measures 6 1/2" from the unit to the top. The intake screens are in great condition, with no signs of cracking. There are some scratches and scuffs in the paint, but this is purely cosmetic. Please note that this does not come with the trim tab, the propeller, or the propeller hardware. These things can be used from your current lower unit. This unit has a 2.33:1 gear ratio. Given our unprecedented 1 year warranty on this lower unit, you will never find a better deal on an OEM lower unit.  Purchase with confidence!

If you are unsure whether this is the correct lower unit and correct length driveshaft for your application please contact us and we will be happy to help you buy the correct product.
