The Smart Buyer - Different strokes: 2- to 4-stroke conversions

The transition from 2-stroke to 4-stroke is getting easier as manufacturers continue to reduce the weight of their engines. The new DF200A from Suzuki is an example of a lighter 4-stroke.Four-stroke outboards are more fuel-efficient, quieter and cleaner than ever. Manufacturers are also reducing the weight of these engines with their second-generation models.

Suzuki and Yamaha have added 4-cylinder 4-strokes to their offerings to complement their V-6 counterparts. The new Suzuki DF200A weighs 498 pounds, about 12 percent less than the company’s V-6 200 models. Yamaha’s new 487-pound F200 weighs 119 pounds less than its V-6 F200 and only 14 pounds more than its 2-stroke Z200 HPDI outboard.

The refit of this Mako involved building a full-height transom to accept an engine bracket.Refitting a boat can be an enjoyable and rewarding task if you undertake it with the proper attitude and planning.
