Direct Intake And Engine Cover Ventilation

A new engine cover design provides the direct intake system with a smoother, cooler flow of air boosting engine operating efficiency. This, together with a newly designed air cleaner allows higher power output from a small displacement.

External Air Flow

The rotating flywheel helps reduce temperatures inside the engine cover by venting warm air to the outside from the recoil cover, inner air intake, and engine upper cover.

Offset Crankshaft

Positioning the crankshaft slightly off center of the cylinder reduces lateral pressure against the cylinder wall as the piston moves up and down in the cylinder. The result is smoother piston movement, which improves operating efficiency.

Easy Start Recoil

Fuel injection delivers easier starts, but Suzuki goes a step further incorporating a very light recoil starter into these outboards. Requiring less pull strength, the Easy Start Recoil Starter makes starting the outboard quick and easy.

Engine Monitoring LED Indicators

The LED monitoring system utilizes three LEDs to keep you informed of current operating conditions. Located in an easily visible position, the LEDs provide easy to understand monitoring at a glance so you can enjoy a pleasurable boating experience.

Engine Flush Port

To help protect the engine from damage caused by salt, sand, and dirt that can build up in the engine’s cooling system, the outboards are equipped with an easy to access freshwater flush port to make cooling system flushing as easy and convenient as possible.

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.
