Have you bought a new boat engine for the upcoming boating season? Before starting up your new engine, check out the Mercury Service blog entry on the importance of engine break-in.
According to the Mercury Service blog…
Engine break-in is performed to manipulate certain surfaces within the engine. Even with current machining processes, there may still be some irregularities on machined and honed surfaces. The break-in process allows the engine to wear down the high spots of these irregularities, providing a smoother surface before the engine experiences the rigors of normal use. The main areas of break-in focus are the cylinder walls, cam lobes, clutch engagement surfaces, and gear engagement surfaces. Engine break-in also helps seat the piston rings and helps to maintain tighter tolerances and better lubrication of moving parts, prolonging engine life.
