Myth: Four-stroke outboards are more fuel-efficient than two-strokes.

You’ve got to burn fuel to make horsepower. Comparisons are often made between older, carbureted two-strokes and newer fuel-injected four-strokes. In those cases, the enhanced economy comes from the fuel delivery system, not from the number of revolutions in a power cycle. Compare modern two-strokes like Evinrude’s E-Tec outboards to modern four-strokes, and the difference is too close to call. Check our boat test database and see for yourself. Myth: Busted

Myth: You can’t store batteries on a concrete floor.

Concrete, wood, shag carpet…it does not matter what surface batteries are stored on. The plastic case insulates the plates. This myth dates back to when batteries were cased in hard rubber instead of plastic. The rubber was somewhat porous and the moisture present in a cement floor could cause a leak to ground. Today’s plastic battery cases are not at all porous. Myth: Busted


Myth: A V-bottom turns better than a catamaran does.

Anyone who believes this myth has never driven a performance catamaran like a Skater, an MTI or a DCB. Compared with a stepped V-bottom such as a Cigarette, Fountain or OuterLimits, the cat will out-corner it and accelerate harder coming out of the turn. To get a real feel for G-forces in a boat, take a ride in an outboard-powered tunnel hull driven by an experienced pilot. Myth: Busted

Myth: Stainless steel is the most corrosion-resistant metal.

Ever wonder how come most boatbuilders use either bronze or plastic through-hull fittings below the waterline and not stainless? The main reason why stainless steel isn’t used more frequently below the waterline is that stainless steel needs contact with oxygen to resist corrosion. The damp microspace where the fitting passes through the hull is an oxygen-depleted environment, and in that environment, stainless rusts readily by a process known as crevice corrosion. We’ve all seen stainless tow rings and bow eyes above the waterline rusting from the inside out. Remember this: It’s called stainless, not stain-free. Myth: Busted
