20'cc versus 23'cc

[cSickNick]

There is a big difference in fuel use; the 23 will use almost twice as much. A SC 20 rigged with a new 4 stroke or etech around 150 hp is very fuel-efficient.

Is this really true? I know my 20' rig does well with fuel, but would a 23 use double? [img]/images/graemlins/blush.gif[/img]

You'd have to ask some 23' owners what their burn rate is, but I'm getting an honest 5mpg with the Suzy 140 on my 20' at a cruise speed of 30mph (Floscan reading 6gph at 30mph) ...and that's with a full 75 gallon tank of $3.69/gallon gas

I've seen 23's powered with large thirsty engines burn 3x that much gas at 30pmh. All depends on what engine you have I guess.

Then again, you can handle a much rougher day in a 23'

With my twin 150 HP Yamaha 1998 carb engines I get a great 1.5 miles per gallon. Maybe a little better, but not much better.
