only yust replaced the ingnitioncaop, rotor and sparkplugs.
found out that there were NGK TR55 sparkplugs mounted in my mercruiser engine (4,3 l)
they were a bit longer thann the original ones.
think they belong in a vehical and not in a boat.
engine runs smoother now and has a better pick-up

i'm talking about the sparkplugs i found mounted in my engine (the NGK TR55).
they don't seem to be suitable for marine engines and the electrode part was even a bit longer than the original Delco sparkplugs.
odd spark plugs
