MARINE REPLACEMENT PARTS THAT ARE IGNITION PROTECTED
IN AND AROUND THE ENGINE COMPARTMENT.
Engines function based off four principles, fuel, compression,
ignition, and exhaust. The 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, electrical, and ventilation systems. The specifi c
details of these systems can be found in your owner’s manual for the
specifi c engine option you chose on your Regal boat. These options
are limited to specifi c single drive Mercury and Volvo engines.
Engine Mounts
The engine is placed in the boat on a set of metal or wooden platforms
called mounts. These rubber insulated mounts keep the engine from
moving laterally and athwart ship (right angles to the center line), as
well as reduce vibration from the engine and drive. Periodically, the
mount hardware should be checked for tightness.
