Suzuki DF50AV

Mechanically Efficient DOHC 12-Valve Engine

Based on Suzuki’s DF60A, the DF60AV/50AV uses the same in-line three-cylinder engine with a 941cm3 displacement. This high-performance engine features a 12-valve DOHC powerhead with four valves per cylinder, and an air intake system optimized for maximum efficiency in the high rpm range. When Suzuki engineers designed this engine, they focused on improving mechanical efficiency by reducing mechanical loss. Each part and component was redesigned with this in mind, resulting in components like an oil pump that allows oil to flow through the lubrication system with less resistance, keeping moving parts better lubricated. All the reductions in mechanical loss combined add up to greater fuel economy.

Suzuki's Lean Burn Control System

Suzuki’s Lean Burn Control System was first introduced on the DF90A/80A/70A four-strokes as an intelligent fuel delivery system that achieves remarkable improvements in fuel consumption. By monitoring engine performance and operating conditions in real time, the system predicts fuel needs to deliver a leaner fuel mixture to the engine producing benefits from low speed operation up into the cruising range, where the engine is used a majority of the time. In-house testing shows that at medium speeds, both outboards show remarkable improvements in fuel consumption over their non-lean burn equipped predecessors.

Most Compact, Lightest Designs

When it comes to building the lightest, most compact four-stroke outboards, Suzuki is clearly the industry leader. Following in that tradition, the DF60AV/50AV are engineered from the ground up using parts and components that are designed to be as compact and lightweight as possible while maintaining their functional integrity. This makes the DF60AV and DF50AV the lightest and most compact high thrust outboards available in their respective classes.

Suzuki Easy Start System

Starts are quick and easy with Suzuki’s Easy Start System. No need to hold the key, just turn it once and the starter system stays engaged until the engine starts. The system delivers smoother and improved starts to get you up and running quicker.

Multi-Point Sequential Electronic Fuel Injection

Suzuki pioneered the use of multi-point sequential electronic fuel injection in four-stroke outboards. This advanced, time-tested system gathers operating data from a series of sensors located in key areas on the engine, processes the data and calculates the optimum amount of fuel and air needed for the engine—all in real time. Boaters benefit with smooth starts, maximum operating efficiency, excellent fuel economy, and reduced emissions.

Self-Adjusting Timing Chain

The original DF50 was the first four-stroke to feature a timing chain and the DF60A was first in the 44.1kW (60PS) class, so it’s only natural that the DF60AV/50AV are equipped with the same. The chain is oil bathed and is equipped with an automatic hydraulic tensioner that maintains proper chain adjustment for maintenance free operation.

Suzuki's Anti Corrosion System

Suzuki protects the outboard’s exterior from harmful corrosion with its own specially formulated anti-corrosion finish. Applying the finish directly to the outboard’s aluminum surface, allows maximum bonding of the finish to the surface to increase durability and help protect parts that are constantly exposed to saltwater.
