Spark plug gap?

[JimHendrix]

I'm changing out the plugs on my 97 speedster. Can someone tell me the correct gap needed? For some reason I think it is .21... but this is my first time changing them so I don't really know for sure.

Thanks

Without looking it up I think it's about .022".

My 2009 180SE calls for .028 to .031 gap. The owners manual should include the info - mine does.

newbie question here...

I bought new sparkplugs supposedly for my 97 speedster.

Do I need to do anything beyond screwing them in? I had never heard anything about spark plug gaps before reading this forum. It's got me concerned.

Different boat, different motor, different spark plug, different gap. The question was for a 97 Speedster, with twin 717, 2-stroke.

Yes you should gap the plugs for .021-.022". And Welcome to the SeaDoo forum.

I have a 2007 Speedster with 210hp Rotax engine.. I never received a manual when I bought the boat new in 2007 and the dealer went out of business. Does anyone know the gap for my spark plugs? also, where can I download a manual?

thanks.

Hi and welcome to the SeaDoo forum. You can download a service manual for you boat on this forum, but you will need to join as a premium member. Or you can just google for one and probably find it elsewhere.

You should post your question in the 4-tec boat section of this forum, I'm certain someone there can help you.

I have a 2002 and the shop manual indicates 0.20-0.24. Hope this helps. I wouldnt think there would be a great deal of diffrence since mine is a carburated dual 717 set up like you have.
