I got this motor running and it makes like clanking noises but i cant tell where its from. Its got spark on all 4 cyl. Also no visible damage to piston heads, 125 psi on 3 and 115 psi on 1 cyl. Noise is there whether in gear or not. I have a video of the sound but cant post it here. Any ideas...
Hi everyone,
I got my hands on a merc 40 4 cyl with oil injection and i have no idea what year it is as i cant find any badging but i was told it didnt run. I build a stand and now im ready to start investigating but its was in a boat with remote and steering wheel so now i need help knowing...
