Spring tune up -- what's necessary?
My Mercruiser 350 normally gets a spring tune up, i.e. new plugs,
timing, etc, etc. Are new plugs necessary every year? What *must* be done every spring. All the fluids were changed in the fall, and the batteries were kept on a charger most of the winter. Thanks. John H On the 'Poco Loco' out of Deale, MD on the beautiful Chesapeake Bay! |

If they look slightly worn of cracked replace them. Bert |

I go through a ton of plugs every spring - all the lawn equipment, snow blowers, and my two antique trucks which maybe get used maybe 450/500 miles per year each. It really depends on usage - if you have lots' of hours on the engine from the previous summer, then yes. I winterize my FICHTS in the fall and in the spring, have the plugs changed so they are fresh for the season. It's a personal thing and I have no absolute reason, scientific or anecdotal evidence to back that up - it's just opinion. It's certainly cheap enough to change the plugs, so why not? Later, Tom S.

Russel Chatham, "Dark Waters" (1988) On the 350, several of the plugs are a real *pita* to reach. They are cheap though, so guess I'll just bite the bullet and do it. Thanks for the reply.

To each their own I guess. I've had the same plugs in my merc 5.7 for 5
years now. They still look good, they're staying in. Just last week I finally replaced the plugs in my mother's 4 banger toyota truck at 90K miles. My 10 year old mower still has it's original plug. Plugs don't last forever but they sure last longer than one season. "Short Wave Sportfishing" wrote in message ...

He said that airspace in the tank over the winter can cause problems with condensation. I've followed his advice for three winters now and I haven't had any problems. |

Lloyd Sumpter "Far Cove" Catalina 36 - we doan need no steenkin' spark plugs! Lloyd, getting *to* the plugs is the problem. If I could pull the engine my life would be much simpler. The plugs are under the exhaust manifold. Once I had them out, I'd for sure replace them. John H On the 'Poco Loco' out of Deale, MD on the beautiful Chesapeake Bay! |

If the electrodes aren't eroded, all is well. If the center electrode is worn so that it is rounded over, or the top electrode is eroded, then replace. |
