The Camshaft of a 4-Stroke Outboard Motor

There are several benefits of a 4-stroke outboard motor. One of them is a smoother ride, which is important when you're cruising on a lake. Another advantage is the fact that these engines are easier to repair. In addition, they can operate in any body of water.

A 4-stroke outboard motor's camshaft is different from that of a 2-stroke outboard, which uses a single-stroke combustion engine. Two-stroke engines use a single crankshaft revolution to generate twice as much power as a 4-stroke outboard. In a 4-stroke, the piston makes two additional transits through the cylinder, so it requires two complete cycles of the cycle before the engine is ready for a fresh start.

The camshaft and crankshaft are located inside a case, which is secured to the crankshaft by a locking nut. The case part 105 is disposed in the cylinder bank stagger, while the drive sprocket 87 is disposed in the scroll recess 118. A spacer 154 is interposed between the sprocket 87 and the camshaft 79, and a drive pin 155 ensures rotation.

The four-stroke outboard engine is known for its smooth and powerful performance. The engine also has low emissions, low noise level, and low fuel consumption. It also features a self-contained oil cavity and an oil filter. Oil changes are typically necessary after about 100 hours or a year of use.
