Which Spark Plugs

[geckoman]

I have a 2000 Seadoo GTX. I believe it's the DI model, not 100% sure. It has the blue hull with silver seats. The SeaDoo shop just replaced the fuel filter and cleaned the carbs but didn't chang the spark plugs. The spark plugs that are in there now are NGK BR8ES but I see where they should be the ZFR4F-11. Which one's belong and does it matter?

The plugs need to be the ZFR4F-11 gaped at .021-.024" The heat range is close to the BR8ES.

Thanks..I raelly appreciate the fast response.

The Seadoo shop told me they are pregapped but I am sure you will tell me to double check.

No, the spark plugs are never pre-gaped...usually I have found that out of the box they are at about .038" on average...always check the gap for an accurate gap. The gap is real important.
