Spark Plug tubes/o-rings - If one plug is leaking, buy new for all?

I was planning to use the transom (boat) plug to pull out the tubes. Based on your post, it sounds like it may not be as easy as some of the web sites make it sound.

Would you care to share any insights into how you ultimately succeeded? Do you think there is a better tool for the job?

Thanks

I'm going to try snap ring pliers with silicone tubing over the ends.
