2 stroke mercury outboard compression chart
#1 Hello all, I have a new-to-me 2004 25 hp 2 stroke Mercury engine that seems to start and run well. During a cold engine compression test, the cylinders both hit exactly the same at 100lbs. My question is: What should the compression number be? This engine is very clean with very minimal use.#1 Looking at buying a 16' Lund with a Mercury 40 HP, 2-stroke motor. This engine has the 4-cylinders, and appears to be a '91. Engine hasn't been run in two years, and when I ran a compression test, I got the following results: 120, 120, 105, 120. I wanted to get some input regarding those numbers.
