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).

Individual Sensors

6 individual sensors provide constant vital engine information to the ECU for maximum efficiency.

High Output Alternator

The 115 TLDI® is equipped with a high output alternator that produces 37 amps of power even at 1,000 rpm and a whopping 40 amps at wide-open throttle.

Idle Noise Reduction System

The exhaust gases and the sound are routed through the labyrinth exhaust. This process reduces the noise level to a minimum when exiting above the water line through the idle port.

Engine Control Unit (ECU)

The 32 bit engine control unit controls the fuel injection and ignition timing for TLDI® outboards.

Fresh Water Flushing Port

The 115 hpTLDIR comes standard with a convenient built-in freshwater flush system. Located on the side of the engine, the flushing port simplifies routine engine flushing.

Air Compressor

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.

Multifunctional Tachometer

The tachometer informs the operator of potential problems through the meter indicator and warning lamp. (Remote models only.)

Pistons Dedicated to TLDIR Outboards

Teflon coated pistons (equipped on MD 75/90/115) with a concave shape to the head were specifically designed for TLDIR and significantly increase the fuel combustion efficiency.

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.
