Yes, it's a minor thing for many, but it's my first time doing it on my boat that I've owned for, what, 13 years....(I typically have the mechanic do it). Cap and rotor next - contacts look a little crusty. I'm trying to pinpoint what sounds like an engine miss at mid-range RPM. Already changed fuel filter and added new fuel. |

Hopefully you checked the gap on them. I just installed some that were probably gapped .010 and the manual calls for .030 |

I pull mine out each spring to check; if they're not fouled I check the gap and re install with a bit of marine grease on the threads; salt water use you don't want to leave em in too long. |

I need to do this as well. I've got the 5.7 GSI and took a look at the situation a few eeks back. how much trouble did you have getting to them. Mine are hidden pretty much from view by the manifolds so everything looks like it needs to be done by feel. Did you use a special spark plug socket? |

No trouble I use a standard socket. The design of the manifold does determine to an extent how easy this is to do... |

Port side was more accessible - I had to move my starboard battery to access a couple on that side. I just used a ratchet with an extension and a 5/8" plug socket. |

Mine are practically all by feel as well. Have to use two extensions with a u-joint/swivel as well... What a pain. |

Lou - out of interest, why marine grease instead of an anti-seize compound? In a salt water environment anti seize can cause corrosion problems if it has copper in it and is in contact with metals that are less noble than copper. I use OMC/Bombardier triple guard grease and I just smear a bit on the threads. They always come right out and this boat sits in the salt air on the mooring for 6 months out of the year. I have the original OMC shop manuals and nowhere is anti seize recommended for anything. To prevent seizing and corrosion they recommend OMC gasket sealer on threads that go into aluminum. So for all the bolts on the drive that's what I use and they all come out also. I have found from past experience that anti seize can cause caking in the threads and actually make it harder to remove things. If you use it just put on a thin coat. |

Also, just a recent post on spark plugs, all new plugs are made with an anti-seize built in. The thread listed 10+ websites of manufacturers not recommending anti-seize. FYI, Doug |

The Drop Point of a marine grease is typically around 250c, where as an anti-seize grease can be in excess of 1000c. |
