Have you ever tried riding your bike up a very steep hill? It's nearly difficult unless you utilize the proper equipment to boost your climbing force. It's a different story once you're back on track. You can move exceedingly quickly by changing gears: you can magically make your wheels spin far quicker than you're peddling. Gears are used in a wide range of machinery, not just cars and bicycles. They're a simple technique to increase the speed or force of a machine or to transmit the force in a different direction. Gears are basic machines, according to science. The 18-2205 Upper Unit Gear Set from Sierra has a 1.98:1 ratio. Mercruiser 120/140 (s/n 2791957 and above) and Alpha Gen II (s/n 0K999999 and below) drive units are compatible. Each package contains one driving gear and one driven gear. GLM 11240 and Mercruiser Stern Drive 43-55766A2, 43-55766A3, and 43-55778A3 are interchangeable. Sierra products exceed the specifications of the original equipment part they replace.
