Changed them all this weekend. One engine, the plug cover nuts we so tight and seems to be jus smaller than 10mm to round off. So I had to go at the with vice grips. seems the last person to do it cranked them on and used a TON of thread lock. Thankfully, the plugs came out easy enough. Used the antisieze everyone recommend here. Took about 1.5 hours for both engine and teaching my boy how it's done. The boat had just under 100 hours when I got it this season. greasing all the required spots is next.
