At the shop today was a tray of everything in the bilge cleaned metal shavings, particles to chunks, bolts and carbon... .two crew members combing through with tweezers. The video he has has been slowed to 45 frames a second to allow him to retrace the events
G. Stray does not sleep until he knows exactly what failed and why. He will complete a full root cause analysis to ensure w don't encounter this again.
The shaft guards will be upgraded regardless.

Stray will figure it out... then go push for more.
I'll NEVER forget the time we through a rod out the block, off the floor and through a cinder block wall.

Without looking at the failed part, there is no way to determine WHY the part failed. It doesn't matter how thick or strong you make the part, it the part is made with a microscopic crack in it, it will fail prematurely. One failed, but not the other, so why? Does the other show signs that would give you an indication of why this one failed? I'd want to do a UV inspection for all the signs of fatigue/failure.
As to the shroud, Carbon Fiber is incredibly strong, but may not be the right material. When we cover turbine blades (20-40,000 rpm for a fan) we use kevlar, not CF. Ballistics vests are Kevlar/Aramid, not CF. CF is great for structural items, but not explosive containment.

On the inspection side, x-ray, ultrasonic shear wave, magnetic flux and die-penetrant are your choices, properly engineered design is your best solution.

10,000 views in a day and a half. Just wanted to note that the part that failed (driveshaft U-Joint) was NOT a Mercury Racing supplied part It was an outside vendor and that is clearly the failure point. The concept of showing this video other than being an awesome display is to show the immense forces at play in our boats nothing more.

Thank you again for posting it. Y'all could've been all secretive and hush-hush, but you weren't. Shows the level of class of your team. Good luck!

These videos and info about what happened keeps many interested in what is going on in racing. It is also informational, pointing out how important that driveshaft and guard are. Most boats only have covers to prevent someone from step on a rotating shaft or getting something caught in it, not many are designed to contain the shaft. Even if they are designed to contain it, they are not always successful! Thanks GEICO for the great video post, I am sure you will be ready for Cocoa Beach!
