I'm currently running some champion RV12YC plugs wich came with the boat, I think it might be time for changing them.

Autolite is not an option since I cant get them here, can anyone tell me wich other brand and part should I look for?

It would be interesting to have a guide insite on wich plugs for each brand go on each engine, stock and modified, what do you all think? Keith?

I am not Keith but if you click on reference on the top then click on manuals and scroll all the way down to pleasurecraft 302/351. They will list all of the plugs you can use as well as other engine info! I just found this tonight myself!

Before I swapped my GT4oP heads on, I ran NGK V power plugs. They are cheap, and are said to actually be worth a HP or 2 vs new normal copper plugs.

I forget which number they were, but I ran that last set for 5 years with no issues, even with a carb that wasn't set right, failed original point setup, and then an intake manifold gasket leak, and minor head gasket leak on both sides. They always fired the boat right up despite those issues.

I went with autolite 764s on the gt40p's since they were on sale for a dollar each, and most folks use these plugs with their P heads.
