I have a 2006 merc 25hp 4/stoke EFI ( OR107138 )
This engine will not run or even pop. i checked compression with throttle wide open and can only get about 10psi on all 3 cylinders. what could be causing this? i know this engine has decompression valves built on the cam but i should get more compression than 10psi right?
I did put new rings thinking maybe it was that. (this engine does have a lot of time on it) but the compression did not change. im stumped, and dont know what to try next.. any help would be greatly appreciated.
