In Feb 04 "Boating" magazine they have an article on "Horsepower vs Horses @#&! Are bigger engines a better buy?"
Tested Volvo Penta's; 280-hp, 320-hp and 375-hp.
Excerpts from the article:
"The answer: Even though there is a 40-hp difference on the printed spec sheets, there isn't that much of a difference in real life.
Here's an important lesson when you're shopping for a boat. Manufacturers allow themselves a fudge factor when publishing horsepower ratings. An outdated industry agreement permits a leeway of plus or minus 10 percent in published horespower. Sometimes an engine model may have less than its rated power, and sometimes it may have more."
"If you want more performance the only way to get it is to opt for the big-block engine. Anything in the midlle is not likely to be worth the cost."
