Sparky Plugs :)

I currently have an '84 Johnson 140 2-stroke "Looper" engine on my boat and the plugs have lasted about 13 years. I know that's probably crazy, but the aged gentleman that I bought the boat from said that all he did was brush the ends when it needed. The plugs are Autolite (#2892) and I would like to replace them or have a back-up set handy. I wanted to go with NGK (#BUHXW-1), but I have been told that they fowl quite often in 2-stroke engines. My other choice is a Champion (#UL77V), or I could just go back with an Autolite :) Basically, I'm open to suggestions!

I have found at top end it doesn`t really matter, but I have tried them all litterally and I know my 1975 Johnson 85h.p. V4 likes the Denso brand the best in all ranges, especially shines in the Trolling Slow mode, they don`t foul easily or stall out easily, hands down the best plug for the money. Now on a 9.9h.p. outboard, it seams those things will run great on anything at any speeds!! Jack.

In all of the shops I have worked at we have used NGK in everything with no performance complaints from any customers.
The only engine I have ever encountered that liked Champions better were the early Force 85s. Wouldn't think that old Chrysler ignition system would be that pickey.

in a past life i learned it doesn't take much to strip the threads in alloy heads with a sparkplug...as in bringing the threads out with it? i'd remove them periodically even if they did last 13 years...lm

"If it ain't broke, don't fix it." Go with the replacement plug that is working well for you now.
Or run your own test with various plugs and post it here!

Thanks yall! I believe I'm going to try the Champions, but before I stick with them, I will run that test per Wille...
