What Spark Plugs, Old Outboard ?

[Steve W. Senior Member Find all posts View Profile Close Steve W.]

As you can see in my signature, I have an old motor on my 224.

I always use the Champion plugs that Evinrude reccomends for this motor. I am curious to see what everybody else uses.

Hey Steve, I didn't see anything in your signature about your boat, but anyway. I have a 1987 Suzuki DT200 and I use NGK spark plugs that come pregapped. My buddy goes to a marine tech school and his teacher said that marine spark plugs actually burn hotter than automotive plugs, so there is a difference i guess, news to me. What boat and engine do you have?

Mr. D,

For some reason, I can see it without any trouble.

Anyhow, it's a 1982 224 with a 1983 200 hp Evinrude.

The manual for my old '85 Merc. 150 called for Champions. On the advice from a fellow Merc. owner, I tried a set of NGKs. Night and day. She ran so much better with the NGK plugs.

The manual for my '02 Merc. 150 calls for NGK, so that's what I give it. []

Yeah, just don't buy the NGK plugs at boat us or west marine, I'm not positive, but I remember them being three or four times as expensive there.

I had to get the NGKs for my newer motor at Boater's World. They weren't a stocked item at Auto Parts stores and could only be ordered in batches of 10. I found 6 at BW and they price matched. []

I get mine at NAPA, but every NAPA's inventory is different

I guess maybe I'll give NGK's a shot this year. They have always worked well in my jet ski's.

Do yourself a favor and order 2 or 3 boxes of 10 (30 plugs with a 6 cylinder is 5 complete changes of plugs) from your favorite automotive store. In those quanities they usually will give you a big break in the per plug price (or ask for it).That way you will always have a spare set (which you should be carring on the boat anyways) if you need it. You will also have a new set of plugs for the next several years and you will not need to worry if you run into problems with plugs fowling out. Hope this helps -

Mike,

That would've been a good idea a couple of years ago, but I don't know how much longer I trust this motor to last.

I always do carry spare plugs, and luckily (knock wood) I have never fouled plugs with this motor. I also don't do a lot of trolling either.

That is a good idea though.

I just carry the old plugs as spares. []

Yeah Brian,

That's what I do to, but I didn't want to say that out loud for fear of being flamed.
