I dont know about the gasket but get your plugs at www.sparkplugs.com they are $7 each plus shipping, I got mine in 2 days from Cali to FL.

RTV won't hold the cylinder pressures generated by the combustion.
It's made to seal water passages, oil, etc.. NOT a cylinder. You need that steel ring to hold the pressure or else you'll blow the seal real quick.

[jimmyjr]

um i dont wanna sound stupid but there was no steel ring only the spagetti gasket

[jimmyjr]

and also none of the spark plug companies will ship to canada

[jimmyjr]

also thanks for the quick reply any other ideas

You can not use rtv to replace the o rings but you can use it to replace the spaghetti gasket. Lots of folks doing it. I dont know if they have them up there but i get my plugs from napa here. Cheapest ive found anywhere. And theres no steel in 3 litre head gaskets

[jimmyjr]

thanks hogg,i wont use the rtv for the o rings as i have new o rings,and napa does not have the champion plugs in canada and thanks for clearing up the metal gaskets

Yes. As a matter of fact, why would you "waste" the money on the sketti o-rings in the first place. OMC's been doin that from the factory .. for years.
Now if your really in a pinch, you can take out the "viton {florocarbon} rubber" compression o-rings out. Put a small smear of RTV in the groove, put the o-ring back in up side down and go again ...

i wont be going over 4500 rpm and can i use a ngk br8hs i cant get champions here for any less than 40$ per plug and again it would take a week i am not trying to be cheap i just wanna go on our planned trip,and use my boat.thanks for any and all replies

I wouldnt give ya .40c for a Chumpion sparkplug. I only use NGK BR8HS plugs in a three litre. If yur feeling guilty about only spending $1.90 a plug. NGK offers a plug with a center wire electrode made from unobtanium . Got some x's or z's in the BR8 part number if I remember correctly ..

[jimmyjr]

thanks so much for the reply chaz,so can i use the ngk br8hs?

[vector mike]

I wouldn't put Champions in my lawn mower but I would give them to my competitor.

we use br8hs or br8hs10's all the time, gap them to .028 and go. you can use rtv on the outer perimeter of the head, just clean everything w/ brakecleen and you'll be fine

with these ngk plugs, do u use them on the 300x motors? do u loose any horsepower or mph? the crossreference in ngk for the champions are expensive too. jus cant believe u guys are using the ngk $2 plugs and i am spending $8 on a plug.

[mrcrsr]

have several of them running around w/ them

[jimmyjr]

wow thanks alot guys im going boating finally,fingers crossed
