2003 DFI 250 Spark Plugs

[vigalass]

Guys, I pulled the plug on the right out of my boat. These plugs (right) were in there when i bought it last year and it ran pretty good at about 5600 to 5700 RPM and 48MPH. Before removing them this season, i bought the new NGK plug on the left. I pulled that plug's number from this site. In the end, I wound up not refreshing using the correct plug number becuase the reach is so much shorter than the NGK plug (right) that I took out of the boat. The right side plug is a good race plug and I knew it worked. I'm scared to put the plug in with such a short reach.

Am I pulling the wrong plug number for my boat (left plug) which is a 2003 Utopia 205, but it has a 2002 250 DFI Serial # oe411231. Thanks

Thx

I have also run the champion version as I was in a pinch and that was all I could get my hands on that day.

They ran fine but I did change back to NGK at the end of the season
