If numbers match it should be the same.
Had a 2.5 ltr hot rod Merc that was hard on plugs.. Finally found an auto parts tore that could order them a LOT cheaper.. .
^ ^ ^ As long as numbers match (and no additional numbers or letters) should be same.
I order marine parts from Euro Marine here, and plugs from Rockauto (with my car parts).
Same exact spark plug- ONLY difference is the Warranty provided.
Mercury Parts and Accessories carry a 1-year Parts and Labor Warranty against defects in Materials or Workmanship.
Auto Parts Stores (most) carry a "Replacement Warranty".
So if one falls apart into the engine and destroys the powerhead... that's really the only time it would make a difference. :wink:
Thanks

Portions of the plug missing, evidence of early-stage failure due to debris. I have seen a handful of causes where you could conclusively say a plug failed and dropped a portion of the center electrode or porcelain into the cylinder.
Yes sir..
If that did happen how would one know if the plug that failed was bought with a "replacement warranty" or the Mercury parts warranty ?..
Parts and Accessories Warranty states that: "Proof of Purchase is Required".
:thumb up2:
Don are you saying Mercury plugs would warranty a damaged powerhead if their plug came apart and took out a cylinder?Quote:

I'd be interested to know as well...Quote:

Yes, I have seen this scenario. Have also seen one where a plug took out a powerhead- the customer had even called in to Customer Service to find out what plug to use.Quote:
