I just picked up a new to me boat and I have a couple of questions. I want to change the lower unit oil but can only find two plugs one labeled wash the other vent, they are the same and side by side. I searched but cant seem to find anything close to mine. Its late and Im going to bed I hope for some info so I can het to work in the a.m.

Also how can I unhook the auto oiling system so I can mix it myself and do I mix it a 50:1. Thanks in advance for everybodys help.
