Propane gas, that is. Powering your outboard motor. Really? Yes really… Of course Boat Show means a dazzling selection of boats, many of them with price tags that make your knees buckle… and a legion of pretty girls near or on those boats… and marine beauties of the hull-and-mast kind, too. (Don’t expect decent food though. The main concessions were heart-attack-on-a-plate awful.) But what’s best of all is when you find a brilliant idea like using propane gas to power outboard motors – eco-friendly, easy to refuel (just hook up a bottle), power-efficient, and much less damaging to motors. With an electric starter and a long-life internal battery. But if you meet Captain Bernardo Herzer (picture), you get to know his Lehr outboards in double-quick time. He’ll see to that. And it’s a cracker (as far as this blogger can tell.)
