On details ....

I think that a few Petrol jobs are creeping in here .... so if you are quoting on outboard or petrol -please can you indicate ?

As to details - they will not be ID'd on the table - just a table of Engine when known against boat typicals without names.

ie Jag 27, Yanmar 1GM 10HP 4kts 1.7lt /hr

OK ??? Oh yes .... gallons or Litres - I don't care as I'll convert if necessary ..... even if its US Gallons !! but please if it is US - then please indicate ....

Nigel,

Sorry to be flippant but..........I've just changed from twin 230hp diesels, consumption 140 L (31galls) per hour to a Yanmar 55hp on a 10 tonne nauticat and the thing drinks fuel so b.......y slowly that the numbers are too small to work out! I think I drink more Mountgay & coke than the boat drink's diesel!
