OK I am looking for some suggestions/oppinions on what the best plugs are to put in the boat this year. For some strange reason when I was doing the maintenance earlier this year I forgot to change the plugs out. So I was going to pick some up today during lunch and installed this evening, but I can't remember what size and brand I should install. I am sure there are about 2 to 3 brands that are going to be told to me, so I guess I will go with the most common one mentioned.......BTW just to throw this in here, which oil should be used. If I am not mistaken I used what the boat guru's gave me for my motor. I can't remember the weights though.

I use Shell Rotella T straight 30 weight oil...
Some people use a 15W-30 I think though...
