2019 AR210 Small issues. Extend Warranty?

[TrippinHollies2019AR210]

So far this summer, I’ve managed to blow 2 plugs in the starboard engine of my brand new 2019 AR210. Little to no explanation on why this happened from the dealer, but the Fox River & Chain O’ Lakes is full of surprises. Installed the thrust vector-X fins today & noticed that each screw (unrelated to the fins) under the jets were loose. Some of these little defects make me want to extend my warranty. Heard about loose windows & loose plastic rattling from the cabinet. Anyone else experiencing the same small, but annoying issues?

As far as extending warranty, how many years of warranty do you have now and do you have any YES warranty? What would the cost be to extend and what are your options?

I like having a warranty for these boats given some of what I read and I also have a dealer close by that I could probably work with if I did have a warranty issue. I think that is important to consider also

I'd be very concerned if I had spark plug issues....but are you referring to spark plugs or clean out plugs?

I thought the cleanout plugs in these later generation boats were screw in plugs.

They don’t screw in, they lock. It’s a significant lock but maybe it could vibrate loose. I haven’t seen anyone mention this yet. Interested to hear more

I thought they all screwed in too. @4x15mph can you elaborate on your explanation?

My 2018 doesn’t screw in. They have a tab like config where you put them into place and then twist the plug handle from the “unlock” position to the “lock” position. It doesn’t screw with threads. Understand?

Yes correct the new plugs have 2 tabs that are stationery and one that turns. The
Plug goes down into the port, and you turn the whole plug roughly 45 degrees until it stops. Honestly if the plug is seated all the way and the plug is turned until it hits the stops I’m not sure how it could vibrate loose? If you don’t turn it until it stops then it could definitely back out I suppose.

In regards to the warranty question, I had a few little things like trim screws backing out due to vibration, head/changing room curtain zipper stuck, stuff like that. Unfortunately none of it was anything I’d take it back to the dealer for. After the horror stories I’ve heard dealing with YES, and the solid reputation of the Yamaha engines, I’d save my money and just fix things as they happen. Better investment would be to get the factory service manual and save big time on maintenance by doing it correctly yourself.

Great point by @Dixie Highway . I just ordered the Service Manual last night and with shipping that is $100. You can order here: https://yamahapubs.com/index.php?lang=en

(2) Spark Plugs. As of now, I put on about 20 more hours with no issue. Makes me think it was something else & the dealer was BSing me. The symptoms were: after full out to the next no wake, upon throttling down, black smoke came out of the exhaust. The starboard engine suddenly wouldn’t rev over 5k rpm. I checked the spark plugs & they all looked good. Compression from the cylinders was also good (about 150).
