I can not find new sparkplugs. When I go to autozone, the say theyre not available. Is there a crossover..? I took the boat out for the first time and it wont idle good. I hope that is all it needs

Depends on which engine you have. If it's the 250 hp 351, then AL 24. If it's the 285 hp 351 HO, you want the Autolite 764.

Sorry, I forgot about the HO, besides, if the engine info had been given it would have been a little clearer, but..................nevermind.
