I have searched for the correct type of oil for the lower unit of Johnson '62, 40HP - electric shift. Some posts say type C.<br /><br />I am wondering if there is a generic kind of oil that I can buy of a part store for this kind of enigne? if there is, what's the spec.?<br /><br />OMC dealers are kind of hard to reach over here. <br /><br />Thanks for your advice.<br /><br />Nam
