Is there any reason anyone can think of why it would be better to put new plugs in at dewinterization rather that at winterization? For the past two years I've been putting the new ones in when I pull the old ones to spray fogging oil into the cylinders. Just seeing if there is any reason not to change them in November versus mid-March.

I have always done mine in the spring but it's probably 6 one way, half a dozen the other

But it's an 8 cylinder????

/nah I'm just kidding you. I've got a friend that always says, "6 o' one."

I would do it in the spring so the new plugs aren't sitting with oil on them all winter. the only reason to do it in the winter is to give your knuckles time to heal from getting them out.

Do it in spring AFTER burning off the fogging oil.

I'm not. I don't think about that until Nov. Just hadn't started a new thread in a while.

I've got babysitters with a lake house, a boathouse, a lift, and a course. That said, I may not ski much in August.

I'm with mlange, I'd do it in spring after burning off the fogging oil. The fogged plugs got a good coating of oil and sat all off season.

I know I over-do it but....

When I de-winterize, I pull each plug, spray WD40 in each cylinder, replace plug & fire up. After all the oil is burned - I replace the plugs. The old plugs then go into my 69 Chevy C50.

I put all the fresh parts on in the spring,
except oil and filter.

Not changed mine for 3 years mainly due to the fact I lost the spanner I had and now can't find one to fit!

Got to pull the mainfolds at the end of this season and clean/repaint so i'll do it then.

Why the WD40?

After it's been sitting all winter not running, I like to lube the inside of the cylinders for their first rotation. I'm sure it doesn't do anything except give me piece of mind.

Okay, I'm almost embarrassed to admit it, but I finally replaced my plugs in my '89 this spring - after owning the boat for 9 years. A few were a tad rusty on the outside, but all the electrodes looked great: uniform, still within gap tolerance, and a light tan color. I had been checking one a year for the last 4 years, but figured it was time. I hadn't put many hours on the engine, maybe 200 in the 9 years I've had it. Had a long post on the skidim site about type and gap of plug, so I won't re-hash that here. It's not easy getting them out on the 351, at least on my '89. I figure I'll change them every 3-4 years, or 100 hours from now on. My $0.02
