Re: 2000 150hp Johnson Ocean Pro Lower Unit
The recommended oil is 80-90 outboard gear oil, it has additives to protect the lower if you have water intrusion. Always replace the washers on the vent and drain screw when changing as they are the #1 cause of water intrusion. Go to your local dealer and get a jug of the BRP Full Synthetic Lu Oil along with a pump, they are much easier to use than the tubes that you can buy, and cleaner.
