Key Features: Key Features: This piston set is a cornerstone of any serious marine engine rebuild project. The .020 sizing indicates that these pistons are slightly larger than standard, which is essential when re-boring cylinders during an engine overhaul to account for wear and tear. This precise sizing ensures a tight seal between the piston and the cylinder wall, which is crucial for maintaining compression, preventing blow-by, and maximizing the efficiency of the combustion process. The quality of the pistons directly impacts the overall performance, longevity, and reliability of the entire engine. This piston set is a cornerstone of any serious marine engine rebuild project.
