Boat Engine Basics ~ The Ignition Part 2

Yesterday we began to discuss the basic parts of a boat engine, starting with the ignition system, in an effort to educate boat owners on the basic functions of their boat. Don’t forget that understanding the primary design and purpose of the essential parts of your boat will only help keep you out of the repair shop if something is to go wrong with the operating system of the boat.

The overview of the ignition system ended yesterday with the power stroke being called into action by a spark igniting the fuel in the cylinder. The entire process that was outlined yesterday is timed by the rotation of the cam shaft raising and lowering the intake valves. Then, turned in perfect time with the intakes valves and , the belt from the cam shaft turns the device inside the distributor. In conclusion, if any parts of the engine fail, the boat engine will run poorly or not at all.

However, you can ensure a smoother running engine with Evinrude XD 50 oil.

Boat Engine Basics ~ The Ignition

Doesn’t it make sense to say that you would save yourself plenty of time and money if you knew the basic mechanics of the design and function of your car? Well, the same can be said for your boat. Learning the how your boat engine operates can save you from having to frequent the repair shop if problems are to arise. Therefore, this week our focus will be to better understand the basic parts of a boat engine.

Let’s take a look at the boat’s ignition. The main purpose of the ignition system is to ignite the fuel because when fuel burns power is created. Now, starting at the beginning of this process, when you turn the key to power up the boat engine, electricity will flow from the battery through a voltage regulator and into the coil. Energy is store in the coil until it reaches 100,000 volts. Then, at the right moment, during the compression stroke in a certain cylinder, the coil releases the high voltage through the plugs wires to the spark plug. The spark then ignites the fuel in the cylinder and drives the piston down for a power stroke.

Check back tomorrow for Part 2 of the Ignition series and learn why Evinrude XD 100 oil is friendly to boat engines.
