In keeping with the trend toward leaner, greener powerplants, Tohatsu and Nissan—Tohatsu builds outboards for Nissan—have come up with a couple of paragons of political correctness for 2001: 50-hp and 90-hp outboards that use the same TLDI (Two-stroke Low-pressure Direct Injection) system. The essence of TLDI combines a water-cooled air compressor driven from a belt mounted on the crankshaft with pressure regulators in the fuel rails and a specially shaped piston crown. Together, these components are said to produce a more complete, efficient fuel burn via a precisely timed and positioned atomized fuel plume within each combustion chamber. TLDI satisfies EPA 2006 and CARB 2004 regulations, as do a couple of recently introduced 18- and 6-hp four-stroke models from each company.
