I have a 1985 rinker with a 3.8 litre and I am looking for help find where to buy the plugs that go in the lower unit where you put in the gear oil. I think these also have gaskets or orings.
Theres a diagram of the lower unit and you can click on the part. It'll take you right to the name and number. (I think it's 41 & 42 on the diagram - parts 0307551 & 0311589)
