Lower unit replacement for 1999 Johnson 225 V6

I could not have been more pleased with the quality of the lower unit and the timeliness and professionalism of service from MercAftermarkets. I also purchased the drive shaft, water pump and anodes - again high quality and worked flawlessly. I would highly recommend MercAftermarkets who will definitely be my first call if and when needed again. Special thanks to Keith for his help!

Happy So Far

Purchased for a 2001 Johnson outboard, and it has been performing well since it's installation a few weeks ago. I have to say, the unit actually shifts smoother than the OEM did. No regrets at all, especially with a 3 year warranty. This purchase is a no brainer.
