Suzuki Marine 9.9 Outboard Motor
A Second Generation 4-Stroke Boasting a Light Weight
Suzuki's 12.7 cubic-inch, twin-cylinder outboard motor is available in both 8.0-horsepower and 9.9-horsepower versions. Because it is four-stroke, it does not smoke like yesteryear's two-stroke outboard. Idling in neutral, sound levels registered a whisper quiet 64 dB. During testing, a shoreside admirer commented on how quiet the engine was. The fact that we could hear the fellow singing the motorís praise from 50 yards away was a testament to the 9.9's soft-spoken nature. A Suzuki spokesman says these engines boast a 50 percent longer range than an equivalent two-stroke outboard. And because it is a four-stroke you donít have to deal with premix. DF 9.9 weighs ten pounds less than the previous mode.
As for performance, I tested the Suzuki 9.9 outboard motor on an Avon Rover Lite, a 9-foot inflatable RIB. With its V-hull acceleration, was quite pleasurable. Starting the motor was instantaneous, no matter whether the engine was stone cold, or hot to the touch. The multi-function tiller handle includes the gear shift, throttle operation and throttle friction adjustment. An over-rev limiter and low oil pressure warning protect the engine. Electric start and choke are available.
I like the fact that this motor has an engine oil filter. Other brands of this horsepower do not. With their modest crankcase oil sumps (less than a quart) small four-stroke outboard motors are particularly sensitive to the purity of their crankcase oil. An oil filter provides an extra margin of error. Don't forget to change the oil regularly.
Electric and manual start models are available. One noteworthy option is the 10-amp alternator (4 amps more than the previous generation 9.9) that can be wired to power running lights and a handheld spotlight. I use a spotlight to find my boat in a crowded mooring at night. Flashlight battery powered LED running lights are my favorite, but restrict you to a speed of no more than 7-mph. Finally, the Suzuki Outboard Motor warranty term runs for three years.
