Is there any benefit to using multiple ground plugs vs standard? Most people are saying it doesn't matter then I was wondering why they make them.

Tim, when are you going to step it up to 4 sparkplugs? 
What's his compression and is he running tl? Total loss had more spark energy so in theory it can jump a larger gap correct?
Just trying to compare to my setup running total loss on a 1105 with 50:50 domes

Yes total loss can run slightly higher gap.
But in a salt water I wouldn't recommend it as it will cause spark arcing

I'm wondering why Yamaha and Kawasaki chose to use a spark plug designed for air cooled motors ?

Multi ground plugs work great with magneto based ignition or large saturated enductive couls.

What about liquid cooler sled motors? Can think of a number of liquids that call for the br8es off the top of my mind...

my hunch based on 100% nothing is they started with them in the 80's they worked. If its not broke, why change it.

I have found a couple references now that say the BR9EYA is an updated version of the ES and was designed to offer reduced fouling. They are interchangeable in every other way.
I held a br8es and a br9eya side be each at Napa last night and the eya's are longer by about a 1/16 of an inch, not the threads, the actual tip. I did not buy them because I'm afraid of piston clearance.

The dome is recessed where the spark plug goes, don't have to worry about a 1/16".

Somebody posted those plugs up before in their own thread and I think that's the thread that @Quinc was referencing earlier.
I picked up a case of the BR9EYA's today for me and ScottS to test out. I run my ski pretty fat and then it sits for long periods in between rides so my plugs are usually built up pretty decent which makes for hard initial starting so I am curious if these may alleviate some of that.
I'm game to try anything once. Nothing ventured, nothing gained.

I don't know all that much about plugs but #.0 suggested that B8EG to me years ago and I've liked it. I feel it gets a ski started quicker after sinking in salt than a regular B8 or BR8. I also find its easier to tune a ski with because the electrode is smaller and you can see the porcelain better. Not too much scientific evidence on my part other than running them for the last 5 years or so and having good luck with them.
I ride 100% salt, oem 62t stator and MSD enhancer. Anyway here's some difference between B8ES and B8EG.
