rough idle.......spark plug question

[auwallace]

i purchased my 08 sea pro back in april and it has been a fantastic boat with the 08 opti 150. Yesterday on my most recent trip my engine started idling rough. wot was fine it seems though, although i didn't get to run wide open after i noticed the rough idle. anyways this morning i pulled the plugs, which is the first time i've done it myself, and they looked like this:



after replacing the rough idle was gone as i figured. my question is this. Advance auto parts didn't have the ngk's in stock but had the autolite iridiums which were half the cost. is anyone else running these plugs?? also how often do you find you need to replace the plugs on your opti? Thanks in advance.

update.......DO NOT RUN THE AUTOLITES!!!. I was having a stalling issue at idle so i took it in. I just got my boat back from the shop and they checked everything. They changed out the autolites for NGK's and the motor idled like new again. I learned a lesson and had to pay for two sets of plugs. DON'T RUN THE AUTOLITES.

I learned that a while back on gas weed eaters. NGK's yes, Champions maybe, Autolite no!! They are Ford plugs what do you expect!
