Tickover or neutral -

 

But I am on the western end of the K&A !!

 

......wait for it !

How would I estimate it?

I think my boat's engine will do 1,700 maximum, so I would guess half that or a little more, maybe 900 to 1,000?

But then it may be that the engine's maximum revs are 1,500 (some models apparently are) so I would have to adjust that downwards.

Can you not count the bangs and work it out from there?

Surely this is one of those 'long as a piece of string' questions, depending on engine, boat, gearbox, prop? I crise on canals at 2000 rpm, on rivers at 2500. Max revs 3000, smallest Vetus 2-cylinder.

I was thinking that because its in the Gardner section it was a specific question about Gardner engines which is why I edited my post away.

 

If we're going for all engines then my answer is I haven't a clue, I don't really look when cruising just 'drive' to the conditions as it were.

On my old 4L3W 700 rpm used to give me 7kts through the water, it was the north sea mind

Sorry, I didn't notice the section. 2000 RPM is quite common for us with busy little engines.
