Spark Plug suggestions!

[68glasspar]

I have 1969 85hp Evinrude, Model85993E. The original manual says champion L-19V.
I'm looking for suggestions for something other then Champion. Something that others have had good luck with. I'm in Wi. with elevation of about 1000ft Above SL. This engine is just going to be used for running around, probably no water skiers!

Autolite 2852 is very close. The problem is that Champion had a handle
On the marine plugs for a long time, so
The OEM marine rated plugs sometimes do not have a direct match if you venture outside of the spec plug and just try to cross it

The AC plug equivalent was V4OFF. I preferred them to the Chumpions

Was the surface fired plugs best for these engines?

 

[jimmbo]

That was they were speced for. Back then there wasn't a Conventional Alternate. Use of a Conventional Plug actually alters the Ignition Timing Slightly by placing the point of ignition closer to the Piston.
I like the Surface Gap Plugs and had a Set last over 14 yr at about 600hr on them, and never had a Misfire due to the Plug.

NGK BUH is a replacer for Champion L-19V.
Surface gap style plug.

Do you have any experience with using those plugs? good or bad?

Is the V40FFK the same plug?

 

[jimmbo]

You would have to consult AC Delco to be certain

I have always had better success with NGK over Chumpions...I was also forced to switch to champions due to NGK no longer producing their plug. So far, so good, no complaints yet....

As I am in Sweden Europe, it is easier to find NGK than Champion.
I have NGK BUX surface gap style in my Mercury 800 1972.
I have also NGK surface gap style plugs and Champion UL18V (surface gap style too) in a couple of Chrysler 70-75Hp.
Both brands have been good in my OBs.

I was able to purchase some AC V40FF on ebay! I will give them a try.

My ebay purchase of the V40FF spark plugs fell through! Back to searching

Isn't the QL77jc4 the superceded plug for a 1969 85 hp? That plug will work well in WI.
