Changing oil just because of age is wasting money; oil doesn't really have a shelf life. Hours of operation is what I have always gone by. I sold a boat with a Mercury outboard on it in 2020. The manual said to change the oil at 50 hours, then every 100 hours after that or annually, whichever came first. I bought that motor in 2007 and it had about 120 hours on it in 2020. No way was I going to change the oil on that motor every year with only 10 hours since the last oil change. I changed the oil twice in those 13 years - once at 50 hours in about 2012, and again in 2019 just because.
You used it 10 hours a year?????
Were you dumping bodies?
