but plugs?

[Keith_Menard]

I change the rotor and cap every year...but plugs? Should I do those yearly?

Years ago, I left some plugs in for 6 or 7 years. When I went to change them, 2 were seized in the head and twisted off when I tried to remove them. Boat ran fine, but that's too long. Now I use an anti-sieze compound everytime I change plugs.

That thread title!!! Lol

Way overkill. I think the last plug change I did was around 1000 hrs and they could have easily gone longer. Maybe on a 1970s era motor every few hundred hours would be appropriate but on modern engines plugs can go a long time. Most cars recommend changing plugs at 100,000 miles.

Don’t know how it is on your boat, but on my Response the plugs are super easy to get to. I change them about every 300 hours and keep the old ones just in case. Usually the old plugs still look perfectly fine.

If I would be worried about seizing, I would just remove them, put antiseize on the threads and put them back in.

PCM recommends every 500 hrs, too inexpensive to avoid. Even a slight inefficiency could increase fuel consumption marginal which is more costly than the plugs.

Had iridium plugs for a couple years . Changed out to standard plugs and the boat is running 5-10 degrees cooler. Is that really possible or just some bizzar coincidence?

Geez, I thought the topic was "butt" plugs, maybe something new to prevent enemas. Still laughing!

What???

Changed the cap rotor plugs on our '92 in 2005 at just over a 1,000 hrs. Shooting a little lube spray on them is a good idea.

@Wish, The operating temperature of your engine is controlled by the thermostat so plugs should have nothing to do with that.

I like a person who will create a whole thread just to get a funny thread title!

You should at least be checking them every couple of years.

One 't' away from losing our PG rating. :D

I had no idea what to expect clicking on this thread

I don't know how I am going to top myself on the thread title. I appreciate the input, I think I will wait one more season on the plugs, I think I only put 100 or so hours on and I did change them last year.

 

I installed some heated seats for the passenger side, of course after I finished the wiring I decided I want to give Perfect Pass a main line to the battery, so I will be putting in a relay and redoing it...but a few more hours and some clean up and hopefully I will be ready to go. Oh, also replacing one of my paddle wheels with a temp sensor so I can know how cold the water is at all times :)
