Location: Elk River, Minnesota | Hiya,
The only thing I can think of for replacing the oil at season's end is to ensure there is no water that somehow had gotten into the crankcase, so I would surmise this is more for legal purposes. I could see someone comes back after swamping their motor somehow, water gets into the crankcase somehow, they don't change their oil, and the water in there cracks the crankcase....
I know that there are some rigs out there where the location of the crank case puts part of it below the waterline and with following seas, can have a wave come up higher yet... I would tend to think it is more of a liability statement...
Lower unit definitely at end of season...
