MasterTech Marine is a multi-purpose high-performance boat repair facility, specializing in Mercury Outdrives.


We now have our custom-made # 6 o-rings for sale!
They are die molded into the exact correct shape and are oval instead of round to completely fill the O-ring groove allowing them to seal better and last longer. They are priced at less than half of mercury and a much better product. Replaces 25-846499

Outdrive experience a plus but not a must.
