The 07 article also reported on 9.9s from Mercury and Honda. The Tohatsu MFS9.8A, an 81.5-pound, four-stroke, which we evaluated in June 2007, replaced that model.

Unfortunately, that engine is no longer available. Remember the 75-pound two-stroke? Or Practical Sailors 59.4-pound favorite-the Nissan/Tohatsu 9.8-horsepower two-stroke ( Practical Sailor, Nov. (Engine manufacturers actually label the 9.9 models as вЂњportable.вЂќ) For instance, the two 9.9-horsepower outboards we evaluated in this test exceed 90 pounds. The four-strokes undeniable qualities carry with them a considerable weight penalty. But four-stroke manufacturers still havent figured out that weight thing, no matter what size were talking about. Four-strokes run quieter, burn less fuel, and produce less smoke. Were all glad the old, carbureted two-stroke outboard is fading into history. The Yamaha is more compact, but at 91 pounds, it is no lightweight. On-the-water engine performance tests found the Suzuki to be the loudest and the heaviest 9.9 we tested. Both the Suzuki and the Yamaha are carbureted, water-cooled engines. This report compares the Suzuki 9.9-outboard and the Yamaha 9.9 to the Mercury. These engines are well-sized for large, rigid dinghies or as auxiliary power for smaller keelboats, but their weight can be an issue. Practical Sailor last tested four-stroke, 9.9-horsepower outboards in the June 2007 issue, with the Mercury 9.9 coming out the clear winner.
