Mercury 1976 & UP XL 25" Lower Unit V6 135 150 HP 2:1 Ratio 1 YEAR WARRANTY OEM

This lower unit does have a 2:1 gear ratio and was removed from a freshwater engine. When we opened this up, we noticed that the gears look almost brand new. There are scuffs and scratches in the paint, but this is very common in lower units. This does come with the trim tab. From the top of the water pump to the end of the shaft, it meassures approximately 26-3/8" long and has 8 splines. There are 15 splines on the propeller shaft. Upon inspection, we did notice the skeg has been rounded across the bottom, but this is entirely cosmetic. The unit has been drained of oil and this will need to be added prior to installation. 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.
