Oil change and K&N Filter

[mikeleake]

Hey all,

I recently imported a 2008TT Prostar to Australia with low hours and from reputable seller. The boat is nothing but brilliant and logged 50hrs very quickly, so I changed oil and filter last weekend - very easy job, how good are Mastercraft's!

Question is, I was surprised that the oil looked like it had done some work in that 50hrs and was wondering when others change their oil? Ski speeds are ranging from 28mph-36mph and some barefooting for fun as well!

The other question was does anyone change or service the K&N filter at 50hrs as well? If so how?

Thanks,

Mike
