Re: OMC Type C vs Reg lower unit oil
I believe its actually the lubes' conductivity. Remember there are wires and exposed connectors running into the gearcase which hook into the shift solenoids. The wrong lube will allow current flow and that "freaks out" the shift solenoids. The solenoids, being electro-mechanical devices create their own "stray" currents (with the wrong lube) every time a coil de-energizes.<br /><br />Well, at least this is my understanding - I admit these gearcases are a little before my time.<br /><br />-John
