Looking to buy an outboard convincor.. 25' preferably. I wanted a single due to the astronomical prices of fuel until I spoke to a mechanic who was selling me that a 25 convincor would burn more fuel witha single then with twins. At first I laughed thinking 12 cylinders instead of 6. His argument was that a 25' is a heavy boat and with a single 250 its a dog and plows eating eating gas. With twins he said you can get on plane effortlessly and cruise @ 40 mph with the throttles half way down. Seamed like a good argument but I would still bet on tyhe single. Looking for your feedback....

If your worried about how much gas it will use get a sail boat ,remember there is no replacement for displacement gotta love horsepower
One of my boat magazines did a test on singles vs twins vs triples. The multi-engine boats did BETTER on fuel economy MOST of the time. Just like the sales man said, you will run multi engines with less stress than a single.
The trick is:
You have to compare mph versus mph. At 50 with a single wide open, you'll use more fuel than twins at 50 (which are capable of 65+). Likewise, a pair of twins at 65 will burn more than triples at 65.
Wide open, of course the multis use more fuel, BUT at higher speeds.
