My 3208 needed its valves adjusted pretty often. I did it every 2 years or 750 hours. I did run it pretty hard. Normal 2550rpm and around 900f if I remember correctly. I leased the boat for a few years and the valves did not get adjusted as needed. Ended up bending a push rod and doing some other damage. My Cat dealer told me one nice thing was if it needed to be bored you only had to bore the bad cylinders. Cat built the over size pistons to the same weight as stock so 30 and 60 over size cylinders all balanced.
