Compression in a Johnson 25hp outboard motor refers to the pressure created in the combustion chamber during the compression stroke of the engine cycle. It is a critical factor that affects engine performance, fuel efficiency, and overall power output. Proper compression ensures that the air-fuel mixture ignites effectively, leading to smoother operation and better acceleration. If compression is low, it may indicate issues such as worn piston rings, damaged gaskets, or cylinder wear, requiring maintenance or repairs.
