I have had my 2520sl for 1.5 years and 370 hours. I have never had a issue until the last two times I was out. The fuel/water seperator indicator came on twice, so I decided to open up the deck hatch to get to the sender and take a look into the tank. Let me first say that I love everything about my boat, but am quite disturbed with what I saw. The deck plate was cut out two inches too far forward on the boat, so in order to get to the sender, I needed to cut a bigger hole and will eventually need to get an 8" deck plate installed now. Once I got into the tank, there was a very small amount of water in the back corner, easily siphoned out. But I saw a bunch of what looked to be sand and small rocks in the tank. I siphoned all the gas out first the got a nice sample of this stuff into a clear jar with some of the gasoline. It was small metal beads, which are a biproduct of welding (when the tank was made). I took it to my yamaha servie center for their opinion, and they said the same thing. Now I'm sitting on a boat that needs a polished fuel tank, new deck plate and I am highly, highly concerned about the life span of my injectors since I have run 370 hours before identifying this issue. I have read the threads on injectors and I know Yamaha is not going to pay for a new one because of contaminents in the fuel tank. As of right now, the boat runs perfect and it's a non issue, but who knows what the injectors look like. I guess is was a blessing that I looked in the tank, but I'm waiting to hear back from Robin to see how this can be fixed.
