Why the T50LB High Thrust Excels: More Thrust, Enhanced Maneuverability, and Proven Reliability

For boaters who consistently push heavy loads, need precise low-speed control, or operate in demanding conditions, the Yamaha T50LB High Thrust, in fact, stands out as a true workhorse. Primarily, its specialized High Thrust design, featuring a larger gearcase and a higher gear ratio (2.33:1 compared to standard 50HP outboards), translates into substantially more pushing power in both forward and, critically, in reverse. This is further optimized by the optional Dual Thrust™ propellers, which are specifically designed to redirect exhaust flow for up to 60% more forward thrust and an impressive 70% more thrust in reverse. Consequently, you gain unparalleled control and stopping power. Furthermore, the 1.0-liter, four-cylinder engine with Electronic Fuel Injection (EFI) ensures smooth, quiet operation, easy starts, and remarkable fuel efficiency. The T50LB is, therefore, engineered to deliver powerful, dependable performance, year after year.

Core Features of Your Yamaha T50LB 50 HP High Thrust Outboard

High Thrust (T-Series) Design

The defining characteristic of the T50LB is its High Thrust “T” series designation. This means it’s built with a unique lower unit that features a larger gearcase and a significantly higher gear ratio (2.33:1). This specialized design allows it to swing a larger, low-pitch propeller (like Yamaha’s Dual Thrust™ propellers), generating immense pushing power for heavy loads and providing exceptional thrust for precise maneuvering, especially in reverse.

Optimized for Torque and Control

Unlike conventional outboards designed for speed, the T50LB is purpose-built for torque. Its 1.0-liter (996cc) In-Line 4 four-stroke engine delivers robust power to the large propeller, ensuring strong acceleration even with heavy loads and precise low-speed control, essential for docking or maneuvering in tight spaces.

Electronic Fuel Injection (EFI)

The T50LB benefits from advanced Electronic Fuel Injection (EFI). This system precisely meters fuel delivery, ensuring quick, reliable starts, crisp throttle response, smooth idling, and optimal fuel economy across the RPM range. It also contributes to cleaner emissions and consistent performance regardless of temperature or altitude.

Long (20-inch) Shaft

The “L” in T50LB specifies a 20-inch shaft length. This makes it ideal for single or twin engine applications on pontoon boats, larger aluminum fishing boats, utility boats, and sailboats, ensuring proper propeller depth and maximizing the benefits of its high thrust design.

Electric Start and Power Trim & Tilt

The T50LB comes standard with electric start for convenient push-button ignition and Power Trim & Tilt for effortless adjustment of the outboard’s angle. This allows you to fine-tune your boat’s performance, easily navigate shallow areas, and fully raise the engine for mooring, trailering, or maintenance.

High Output Alternator

Equipped with a robust 16-amp alternator, the T50LB generates ample power to keep your boat’s battery charged and run essential electronics, lights, and other accessories. This is crucial for boats with demanding electrical systems, like those found on pontoons or fishing vessels.

Remote Mechanical Control

The T50LB is designed for remote mechanical control. This configuration allows for a comfortable and precise operating experience from a console or helm, integrating seamlessly with your boat’s steering and throttle systems.

Dual Thrust™ Propeller Compatibility

While the propeller is sold separately, the T50LB is specifically designed to work optimally with Yamaha’s optional Dual Thrust™ series propellers. These propellers feature a larger diameter and a unique design that redirects exhaust flow to provide significantly enhanced thrust in both forward and reverse, maximizing the engine’s high thrust capabilities.

Durable and Reliable Construction

Built with Yamaha’s legendary quality, the T50LB features a robust design, including a multi-point EFI system, a microcomputer-controlled ignition, and Yamaha’s advanced anti-corrosion protection. It’s engineered to withstand the rigors of heavy-duty use and provide years of trouble-free operation.

Perfect Applications for Your Yamaha T50LB High Thrust Outboard

The Yamaha T50LB High Thrust is specifically engineered for a range of demanding marine applications:

• Pontoon Boats: Indeed, it is the quintessential power choice for pontoons, providing the strong pushing power needed for acceleration, cruising, and superior maneuverability in tight marinas.
• Sailboats: Ideal as an auxiliary engine for sailboats, offering powerful thrust for docking, navigating currents, and providing reliable propulsion when the sails aren’t deployed.
• Heavy Fishing Boats: Perfect for larger aluminum or fiberglass fishing boats, especially those carrying heavy loads of gear, multiple passengers, or requiring precise slow-speed control for trolling.
• Work Boats & Utility Craft: Excellent for light commercial applications, barges, or utility boats that need to push significant loads or operate in challenging conditions.
• Displacement Hulls: Provides efficient and powerful propulsion for boats designed to push through the water rather than plane, offering excellent control and fuel economy.
