Oil Change

[Yellowmobius]

What is the recommended oil change time when running synthetic oil? Is it still 50 hours?

I would say every 50hrs. is okay. It has been awhile since Mobil1, and other name brand synthetics. I would verify with Indmar(for warranty sake). Brian Raymond

I just recently purchased an inboard engine manual and it still recommends you change it every 50 hrs and after prolonged storage ( 30 days or more (winter) ). I would stay with the 50 hours, not like it costs alot to change it out but it could definately save you thousands in the long/short run.
