In 2019, Suzuki updated two popular DF150 and DF175 engines with the introduction of the 2867cc DF150A and DF175A. see "Big-Block" with a higher compression ratio of 10.2:1, thus increasing the torque, and fuel consumption with Lean Burn technology has been significantly reduced, unlike previous models, making them more economical at low and medium speeds.
Suzuki Lean Burn Control System is an intelligent fuel delivery system that achieves noticeable improvements in fuel consumption.
O2 Sensor Feedback Control System - oxygen sensor feedback control system, serves for the correct functioning of the fuel lean system.
Knock Sensor - the knock sensor monitors the combustion process, ensures smooth and optimal engine operation, and also helps to increase engine life.
Suzuki Water Detecting System - a system for detecting water in the fuel line with automatic engine shutdown in the event of water entering the engine (before it leads to engine failure).
Semi-Direct Air Intake System - A semi-automatic air intake system is built into the hood, which provides air cooling. Colder air can increase the efficiency of the motor in all modes.
Suzuki Troll Mode System (Optional) - setting the optional select switch
trolling mode will allow you to control the speed of trolling.
ALL OF THE POWER, NONE OF THE EXCESS.
Suzuki’s DF150A was founded on its inline, four-cylinder DOHC powerhead featuring a LARGE displacement. Suzuki’s engineers targeted this big block motor, building it to be one of the lightest four strokes in the 150 HP class, beating out the performance of heavier competing frames. This exceptional model comes in Nebular Black and New White and your choice of mechanical or digital controls.
BUILT IN PROTECTION.
Protect your boat and motor from damage that can occur from tilting the motor with the help of a user adjustable tilt limit switch. When adjusted properly, our Tilt Limit System prevents the outboard from tilting beyond a predetermined point.
A SMARTER WAY TO MANAGE FUEL.
Our Lean Burn intelligent fuel management system predicts fuel needs by monitoring engine performance and operating conditions to deliver a leaner fuel mixture to the engine. The result: remarkably improved fuel economy that the environment—and your wallet—will love.
To guard against corrosion, Suzuki protects its outboards with its own specially formulated Suzuki Anti-Corrosion Finish. Applied directly to the outboard’s aluminum alloy, this finish provides maximum bonding of the finish to the aluminum surface. Layering an epoxy primer undercoat, black metallic finish, and clear acrylic fiber finish on top of this forms an effective treatment against corrosion and protects your investment.
FLUSH AWAY STRESS.
Over time, salt, sand and dirt buildup can restrict flow in the cooling system and cause damage. That’s why we’ve equipped this outboard with two freshwater flush ports that make flushing the cooling system easier than ever. With one port located on the port side of the down housing and a second on the front panel, you’ll always have easy access to the flushing system whether the boat is in or out of the water.
