I know this is going to sound pathetic to some, but that's never stopped me from asking questions in the past, LOL. I have a 2015 Suzuki DF 250 that i wasn't able to use much at all last year, so only about 50 - 60 hours total. I need to change out plugs, and I'm determined to do the easy stuff myself. It looks simple - remove ignition coil, then remove plug, check old ones for burn/oil, gap new ones, put them in (18-20 lb-ft), reattach coil. Being that these are original plugs that I'll taking out, I feel like they are going to be hard to get out and I wouldn't want to break one. I used to service my old 2 smoke motors all the time - but then again, I wasn't as paranoid about breaking something on the ol merc. What say you - easy job or have a pro do it? Keep in mind if I try it and can't get one or more out, I'll be in the big line of people waiting for service. I'll need to bring it in now if that's what people think I should do.

Why do you want to replace the plugs? The maintenance schedule says to inspect every 100hrs. (or every 6 months, but we'll ignore that) I wouldn't expect yours to be worn out yet.
At 2 years old I wouldn't expect any problems with removing the spark plugs also.

My service shop says they replace every season for every motor they service. plus, I read the 6 month service interval. I assume it's not just hours on the motor, but elapsed time also. Why else would they say 100 hours OR 6 months?

To make sure that you don't have problems they want you to pull them out and inspect them. I do it once a year. (we only have a 6 month boating season) Around here for recreational use they last 6 to 8 years.

good to know. I think I'll pull them if I have time this spring, but I won't make it high on my priority list. Worse case scenario is I have the shop replace them after this season. Thanks!

If a shop pulls and inspects plugs and re installs them because they look good or even they cleaned them and one fails soon after they will have a pissed off customer.
So for less time and money they just stick new plugs in. their charge rate over comes the cost of new plugs and possible problems.
you do it yourself and it just costs you some time to inspect, clean, and reinstall
