1976 & UP Mercury 25" Lower Unit STANDARD ROTATION 135 150 175 200 HP 1.87:1

THIS IS A STANDARD ROTATING 25" LOWER UNIT.

This lower unit is in great condition and ready for install. From the base of the water pump to the end of the driveshaft, it measures approximately 26 1/4" long.  There are 8 splines on the driveshaft and 15 on the propeller shaft. All the splines are in perfect shape and are not damaged in any way. Please note that this does not come with the trim tab, propeller or the propeller hardware. The paint is a little banged up, but this is entirely cosmetic. The unit has 4 holes drilled in the cavitation plate from prior planing fin use. We have added a skeg gard because the skeg had a little damage. This will come exactly as pictured. Purchase with confidence!

We have drained the unit of oil and this will need to be added prior to installation. 

We do not take returns on incorrectly ordered items. 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. This product is still covered by the mechanical warranty, offered in exchange for your core, that we have stated in the listing.
