What is the recommended service interval on a Volvo Penta 2002 diesel?

Question

My boat has a Volvo Penta 2002 fitted. What is the recommended service interval between the oil and fuel filters being changed. I have heard different reports of 50 and 100 hours. Can you help?

Answer 1

50 hours is not much for a volvo ?

100 seems better .... but still quite low

I would be surfing the net for more info  ?

My penta 70 runs for 1000 hrs before I service it

Answer 2

What does Volvo Penta say?  What does the owners manual advise?  I would go by the book, it is written for a reason.
