Up for bid is the Lower Unit off of a 25 HP Mercury outboard. This is a short 15 inch. It has been sitting a long time. My company went out of business in 2012. It’s been sitting on the side of my house since before then I decided to part out the motor. The motor ran had Spark had good compression. I still have it and Lower Unit seems to be OK. everything turns and she shifts fine. I pulled the bottom drain screw out and the oil didn’t show any signs of water. Of course this Lower Unit has been sitting for a lot of years so take that with a grain of salt but everything works. Please do your research and ask questions if you’re not sure if this is the right Lower Unit for your application such as dry shaft, diameter, number of spines length, etc. feel free to check out my feedback it speaks for itself. I have had my eBay store for over 24 years. I help a lot of people if you have any questions feel free to ask and I will try to answer them and have a great day.
