Here are some numbers for our 46 Westcoast with a single Cummins 270B.* At 1400 rpm we're at 8 knots burning 2.5 gallons/hr.* At 1600 rpm we're at 9.2 knots burning 3.6 gallons/hr.* At 1800 rpm we're at 10 knots burning 4.8 gallons/hr.* Top end is 2600 rpm.* I generally run at 1400-1600 rpm.* My wife likes to run at 2,000+.* I tell her that past 1800 rpm the boat is pushing more water, burning more fuel and she isn't even gaining 1 knot.* I still catch her inching it up all the time.*
The boat wasn't designed as a trawler, but because of the single it is very efficient for it's size.*

*Those are some nice numbers. *It is quite rare you find a boat like that with a single....I would even say extremely rare!!! *And they usually go for cheap because most people looking for that type of boat want twins(and/or speed). *Anyway, I dig your rig!!!
