Engines function is based from four principles; fuel, compression,
ignition, and exhaust. e proper ratio of fuel and air must be drawn
into the engine’s cylinders in order to be compressed by the pistons
and ignited by a spark the force of which pushes the piston back
down, providing the energy used to turn your propeller, before the
engine kicks into the exhaust stage where it expels the by-products.
If any of these four functions fail, so does the engine itself.
Beyond these basic concepts of engine functionality include engine
cooling, lubrication, and electrical systems. e speci c details of
these systems can be found in your owner’s manual for the speci c
engine option you chose on your Regal boat.
