Our 50 TLDI® is leading the way in new technology! The Nissan Marine 50 TLDI® is one of the smallest outboards on the market with air-assisted, direct fuel injection. This outboard provides exceptionally smooth operation and outstanding performance all the while providing superior fuel and oil efficiency.

This outboard is every boater’s dream. Nissan Marine even won the Motorboating magazine’s “Editor’s Choice Award” for this new outboard! The 50 TLDI® is heralded as the outboard to buy for the 21st century!

We have added this new low-pressure air/fuel delivery system to our proven engine block to give you an outboard that is cleaner for the environment while also giving you the exceptional performance you expect from a Nissan. This engine provides lower oil and fuel consumption in a compact yet powerful outboard package. Our 50 TLDI® weighs up to 15% less than competitive 4-stroke outboards and meets all 2006 EPA regulations as well as all CARB (California Air Resource Board) requirements through 2007.

The TLDI® series are Nissan'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 2006 emission regulations stipulated by EPA (Environmental Protection Agency) and CARB (California Air Resources Board).

Engine Control Unit (ECU)

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

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)

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.

Easy maintenance
The TLDI® outboard motors are designed to be simple and have fewer components that need maintenance or service. TLDI®'s do not require oil filter replacements or valve adjustments as compared with four-stroke outboards.
