Spark Plugs

[Jus' Giv'r]

Hi Everyone,
I have a 2.5 280 with 260 electronics and brucato pcu. Its a stock 2007 powerhead directly from Merc. (date stamp is actually 12/06.)
What would you recommend for spark plugs? (currently has Champions, don't have the # with me).
Make and number if possible please.
thanks gary

I have the same setup as you, I run NGK BR8HS, you can find them at most auto parts house for about 2- 3 dollars

I run the merc box with no limiter and I run the BR9HS10's in mine.

 

[patches]

Either of those will work

Agree with either above...I run BR8HS-10's in mine with the exact same electronics (260 with a pcu) in one of my 280. Runs great.

buzhw...hi-dollar but they will work also,

Hey All, Thanks for the prompt feedback. This may be a dumb question..... I am familiar with the BR8HS but what is the -10's mean?
And so I ask for BR8HS-10?

Also, I think mine came with Champion QL77JC4.

8 is the heat range and 10 is the gap.

8 is the heat range .

With NGK plugs, lower the number, hotter the plug

marty is correct..... 8's are a hotter plug, good for lake use. dont foul out as easy. the -10 means they are pre gapped from the factory. run the br8hs the r is resistor. the pcu can act funny sometimes on a non resistor plug. i never cared for the champion plugs in a merc, but i had a friend who ran them with his 260 and pcu for years... they are cheaper.

You can ask for BR8HS-10, or NGK 1134, which is the stock number for them.

If you get the pregapped plugs, make sure you check them at home. I had to go thru and regap them all. I bought 20 plugs (I likes me some spares) and the gap ranged from .020-.036 and I wanted them all at .033-.035.

Great Info Guys. Thanks!!!!!!!!

Got in our first run of this season the other night. You don't need viagara if you own an Allison. As soon as I stepped on that throttle, I had a &^%-on

Is there any reason not to stick with the Champion QL77JC4?

 

[patches]

Champions that I've tried interfered with the ecu.

 

[SLOmofo]

Because there made by Champion!

Actually, I've had no issues, just looking at alternatives and what everyone else recommends. Just making sure I'm doing the right thing.

I will for sure! Thanks again. Also, I'm looking for some ski pole info and started a thread in the general forum if anyone can comment.

I had a lot of load-up problems with Champs and they really weren't consistent. One in 8 or 10 of them seemed to be defective. Figuring out which one was a waste of good boating time.
