Hey guys, I have a 1979 25hp Evinrude model 25904r. Recently I’ve noticed kind of a knocking noise when I’m running it. I don’t recall if it’s a noise it’s always had and didnt notice until now or if it’s slowly developing! I’ll attach a few videos! The compression on both cylinders was 120 and 121 psi! The motor runs great on the high end. At idle it runs mostly good. A little rough at times and stalls every now and then. The carb is clean and freshly rebuilt!
anyways I was wondering if the sounds it’s making while running is normal or if I should look into tearing apart the power head before something goes bad and causes damage.
