its interesting, ive noticed my four stroke stopped making oil after a few seasons of use. maybe its how i run the boat and or using the better merc oil which is part synthetic 25 - 40 . dont know what the former owner used. i feel the engine improves with time now. i have taken it from 350 hours to approx 750 to 800 hours over the past 5 years.
