max revs for a volvo d4 260

[julians]

Does anyone know what the max revs of a correctly propped volvo d4 260 engine should be?

I want to confirm that my new to me boat is running correctly, I think it is, but could do with knowing the official max rev range to be certain.

You should get 3500rpm

Thanks for that, I'm seeing about 3400rpm , so that's probably about right when taking into account wind,differences in boat load etc.

The thing that got me wondering was that I found an official Fuel consumption test sheet from the manufacturer for my boat and engine combination , and that stated the max revs they saw was 3650rpm, and that seemed like quite a large difference even when accounting for difference fuel loads, wind resistance etc. I guess they test in absolutely perfect conditions with a very lightly loaded boat .
