I apologize if this has been posted before, but I found it interesting. To me it reads that Indmar considers boats running lots of ballast, slow speeds with a large load (board/surf) comparable to 'severe service' maintenance interval in a car or truck and has suggested an oil change interval of 30 hours due to viscosity breakdown and other issues. Read the entire thread, as the subject of synthetic oil is covered too.

I could see where the added load and stress could break down oil faster. For me, I surf for about ah hour in the in morning and then spend most of the day skiing up the river and anchoring. I don't spend every minute of my time on the water weighted down and pulling heavy loads.

I think you need to look at your individual use and determine if the 30 hour mark is best for you. Hell, I probably don't put on 30 hours a year anyway.

Article also shows that you need north of 300HP to wakeboard?
