Replacing Spark Plugs

[WChapelle]

I have a 1997 330 Sundancer. It's been running fine until yesterday when it seemed to be running a little rough. I purchased the boat in August of last year so basically I have one about one years use. I'm wondering if changing the spark plugs would help. At least that seems like the least expensive first step.

do the cap and rotor as well, it'll really wake up your engines

+1.

Use the recommended plugs and do not be swayed by snake oil promises.

Might consider the possibility that it is the fuel, not the spark that is the problem. Ethanol is gunking up a bunch of boats in our area.

Have you replaced the filter and added a fuel conditioner?
