The TLDI® series are Tohatsu's award winning outboard motors that have an established reputation for being compact in size while demonstrating highly desired features such as low emissions and high fuel economy that are demanded by the new generation of boaters.
They are powered by a direct fuel injection system and a 32 bit ECU (Engine Control Unit). The ECU gives precise fuel injection instructions in accordance to the operating conditions detected by the multiple sensors located on the motor. The TLDI® outboard motors meets all of the emission regulations stipulated by EPA (Environmental Protection Agency) and CARB (California Air Resources Board).
Multi-Function Tiller Handle is available on select models. The multi-function tiller handle features an ergonomically designed shift lever for easy and convenient shifting as well as a longer throttle grip with 110 degrees rotation for easier maneuverability.
All controls on the new multi-function tiller are conveniently located on the handle for easy access and control. More specifically, the gear shift, throttle control, trim switch, safety lanyard cord, TLDI® warning lights, and electric start key switch are all integrated in the tiller handle.
One of TLDI®'s essential engine components that is the driving force in achieving stabilized fuel injection.
Direct fuel Injection into Cylinders
Due to the intrinsic design of the chamber on the cylinder head, the finely atomized fuel mist created by the fuel injector is injected near the spark plug to achieve ideal combustion.
The tachometer informs the operator of potential problems through the meter indicator and warning lamp. (Remote models only.)
3-Step Trolling Speed Control
The idling speed can be set to any of the three rpm ranges, 700, 800 or 900, by adjusting it on your key switch. This feature allows you to select the ideal trolling speed for maneuvering during a variety of current and wind conditions.
