**UPDATE** 2013 150 Pro XS issues today- How bad is it?

Sorry in advance for the tl;dr

My rig- 2013 Z-7 DC, 2013 Pro XS 150

On Toledo Bend this morning and boat fires up just fine like it does at least every other week. Idle a couple hundred yards out of the cove and make a 5 minute run to first fishing spot of the day with no issues. Fish for about an hour and decide to head across to the Texas side of the lake to a spot about 15 minutes away. Boat ran excellent until about 12 minutes into that trip when it sputtered for a second like it would of had trash in the fuel but quickly recovered. That is until I made it about 100 more yards and the engine starts making a horrific clattering/knocking sound paired with a very generous about of vibration to go with it. So I immediately shut it down. It was very rough idling for a little bit when I decided to try to limp to a nearby marina but it died the second I put it in gear. It would still crank after that but die again when forward or reverse were engaged. After trying that once each, I cranked once more to hear it idle but it died on its own about 5 seconds after crank. Just a note- Oil levels in both tanks good, non ethanol gas with additives, and when it initially sputtered for a quick second, on instinct, I looked down at my water pressure and it was still good @12-13 psi so I'm pretty certain nothing was caused from overheating. Also I never got any kind of alarm from the motor.

Just got it back to town and dropped it off at the dealer but probably won't hear anything for 2 weeks. I do still have the Platinum warranty good until next March (thank God) but I'm just curious of what yall think might have happened and how bad it actually is. Thanks for any input yall have and let me know if I've left out any crucial info.

**UPDATE FOR THOSE INTERESTED**

Just got back from the shop and took a look for myself where there is a quarter sized hole in the #3 cylinder. Wont be certain of what actually caused the damage until they open it up. Now just to wait to hear from Mercury to see how they want to handle it. Hopefully they don't give me any kind of run around which I believe they won't. I'll just have to accept the fact that my fishing season is probably done for the season unless winter decides to be non existent again this year here in SWLA. I'll be sure to update again after we hear from Mercury just in case anybody is curious.
