Looking for marine spark plugs

[Pointer 78]

Who's got'em locally? Also, when installing new plugs, is there something you lubricate the plug with before installing. And yes, I've not done this before.

Hey man, pull one of your plugs and go to O'Riellys, they will have marine plugs that will match. When installing a brand new plug, I always give the threads a really light smear of high temp grease, don't overdo it. Most plugs also have a water repellent end where the plug wire covers the plug, be sure and put enough grease around the perimeter of the cover to keep water out. If you are installing all new plugs, I highly recomend that you spend the $ on a new set of plug wires also. Good luck.

They are usually pre gapped........ not, set the gap.

Flip...these plugs are flat. There's no gap. Go figure. Flippen....It looked like there was some type of light grease at the end of the old plug. Plug wires too huh? OK. Thanks gentlemen.

You can put antiseize on them which is available at auto store. I never use it on boat motors since I change the plugs once a year. If it is a merc, I would use NGK's that is what they recommend. No gapping on flat plugs, and only tighten a 1/4 turn past snug

Ill agree with jon NGKs are the way to go they are a hotter plug than most and usually you can get them at any o"riellys cheaper than the boat dealers

It's best to use the exact plug for your application. If the heat range is too cold the plug will foul, too hot and piston damage can occur. I was at BW last week and noticed they have a selection of NGK's. I found original Champions for my engine in stock at Island Cove.

Use the designated grease to seal your plug wire boots. The wrong grease can conduct the spark down the outside of the plug when moisture is present causing misfires. A little dab of anti-sieze on the plug threads will insure easy removal of the plugs in the future and prevent damage to the cylinder head threads.

Go to your local boat dealer for your parts they will give you the right stuff ! O'reilly's is not a dealer. Put in what the engine calls for not something different. Only if you want your motor to last.
