Mercury 2.5 HP, 4-STK 2018 Short Shaft [ME2.5SM4S] Free Shipping

Mercury Marine’s 4-stroke technology consumes 40 percent less fuel than 2-stroke models for extraordinary value and savings.

Engines surpass California Air Resources Board (CARB) 3-Star Rating, making them some of the cleanest running on the market-with 91% less emissions than traditional 2-stroke outboards!

The inherent 4-stroke characteristics of ultra-quiet, smoke-free operation, plus smooth idling and running make these engines a natural choice whether you’re trolling for fish or out just for fun. Clean running 4-stroke engines have a CARB three-star, ultra-low emissions rating. The decompression system and electronic CD ignition design ensure an easy, reliable start. One-stage over-rev protection and low oil pressure warning system provide extra peace of mind.
