Boat Engine Basics ~ Compression

Compression within the boat engine is yet another essential part of maintaining a steady operating vessel. The compression is more of an action that a specific part of the engine. Here are the basic steps that need to occur to ensure the proper compression within the boat engine takes place:

• The cylinder must not leak any power when the spark ignites the fuel
• The rings around the piston must press against the cylinder wall exactly
• The valve seats must fit exactly in their guides

The timing must be exact in all areas and the parts may not be worn down or damaged, otherwise the engine will not run at full power. However, you can help things along with the clean power of Yamalube 2W oil.
