2016 Yamaha AR190 Won't start & weird rattling noises

[AZAR190]

Hello everybody, I am having an issue with my 2016 Yamaha AR190 (120 hours). I'm located in Arizona, always had the boat in fresh water and always perform the flush after a day of boating. This weekend decided to head out to the lake so I did my pre-departure check routine and fired the boat up for about 5-8 seconds before leaving the house. I had about 1/2 tank and since I was planning on a full day with the kids, I decided to top off the boat before getting to the lake. I fill up and when we get to the lake, start to unload, the boat wont start. It cranks and turns over but does not stay on. After multiple tries, I decided it was time to head back. When I got home I tried to troubleshoot and checked the following:

• Batteries (2) - running at 12.4 volts
• Gas - full tank
• checked throttle - status ok: when in any position other than manual, engine wont crank
• checked all kill switches - status ok: when engaged, engine wont crank
• checked lanyard switch - status ok: when engaged, engine wont crank
• checked clean out port/hatch switch - status ok: when engaged, engine wont crank

I took a videos: Day 1 - No start

The day after, same result and also seems like there's a rattling noise that I am not sure of whether it's my paranoia at this time or something is really wrong: Day 2 - No start

Any ideas or pointers based on your experience? Thank you in advance!

When was the last time you changed spark plugs?

The rattling sounds somewhat normal when I compare it to my boat. Just the sound it makes when it's out of the water.

Hi there, I purchased this boat at 100 hours and the previous seller swore he replaced them So I took his word but after yesterday, that was going to be next on my list...

Ok, so this is a rookie mistake. It ended up being the Spark plugs!!! Obviously the previous owner did not replace them at 100 hours mark and they finally gave out at 120 hrs. I purchased the owners manual recommended NGK LFR6A or 6668 at O’Rilleys for about $33. Swapped em out and voila! Fired right up on first try. Lesson learned!

Happy boating fellas!
