Not sure this is the correct forum, so I will move it if needed. This UOA is from a Mercruiser Bravo 3 outdrive, ~30 hours on the oil, ~200 hours on the drive. Oil is unknown, boat is new to us. Any comments about the heavy oxidation on the oil and insolubles? Clutch material? There is a chance there is a lot more than 30 hours on the oil since the boat is new to us. But, the port drive UOA came back better.
