If you want it to run right use NGK plugs.

If you hold the plugs in your hands, the suggested Champion plug doesn't look much like the NGK plug. The throw is a little different and the heat range is obviously different. Why the recommend Champion plug is so dissimilar is a mystery to me, but I've found the Champion QL77JC4 is a close match and seems to operate identically to the recommended NGK plug. that said, the only reason to do so is if you can't get the NGK plug, or have a bunch of the others on hand for some other motor you happen to own...

The Champion plug has a tendency to foul out sooner then the NGK, so...You will save a little money and do a little bit less work with the NGK.

Hi, the reason I’m asking is because NGK sparks plugs are $12.99 a piece and champion are $1.89 a piece, I haven’t try Napa yet to see if they have NGK but I will check with them today. Here is the number I found so far for the plugs.

NGK- BR7HS-10
Champion- RL82C10

I got does number from a Clymer Tohatsu shop manual.
Do you know any other place beside Tohatsu Dealer, where I can get NGK sparks Plugs?
Thank you

WOW, prices must have gone up since last year! You should be able to get those NGKs at any competent marine dealer. Also, I believe I paid $2 and change a peice. iBoats sells in 10 qty: http://www.iboats.com/mall/index.cg...=105142061&search_in_category=f&view_id=66844 abut $3 each.

Going rate from a marine dealer is $2.99 to $3.99 each. Most auto part stores have them for $2.00 to $2.25 and you can leave out the R in the NGK plugs and use B7HS-10

...I agree with Elvin... leave out the R. The R designates a resistor plug. It improves AM radio reception in some cases, but it costs more, it degrades the spark and shortens the life of the plug.
