i've been trying to work out why my mercuriser
3lt lx is running on only three clyinders.
first i changed the plugs to no avail.
i took out eatch plug in turn and had good sparks.
then while the engine was running i took the plug cap off eatch plug in turn and found one
which made no diffidence.
so found where the fault is but what could be causing it?
another problem of my making was while removing
eatch plug cap to double check my findings the engine suddenly died, and now the plugs dont even spark.
what have i broken now?!
the engine has electronic ignition ( or at least did have )
