sick engine room explosion- HD Miss GEICO onboard

Ok, I thought maybe what I posted may be thought provoking and cause somebody either in a race boat or the boat drive shaft business to really look and see what they are using/producing. Apparently this thread is destined to become yet another "he said she said, what if, how about,etc." You are repeating the comments about loading being more in a boat. Ok, fine. The fact remains I said that SFI has numbers. Those numbers have NOTHING to do with weight, load, whatever. I think if it takes "X" amount of force to break something than that's it, period. Hey, it very well could turn out that the drive shaft Miss Gieco was using is stronger than the pro/ stock, pro/mod drive shaft. I doubt it, but why not try and find out. Clearly what was in there needs to be stronger.
What if that drive shaft went down instead of to the side when it broke? The boys from Miss Gieco very well could be swimming and their boat could be a new playground for the local fish. Do a little research is all I'm saying.

Ben, No worries. Its a good conversation.
I'll call some of our pro drag team friends and see of I can get some deeper info. As for our driveshafts. Very strong...Not sufficient quality obviously.
Thanks Mike. always trying to learn.

benjen - quick question on a Pro Mod or Pro Stock how many runs between u-joints changes? I believe the launch of the car puts more stress on than the prop entering the water but I'm driving at a comparison so if you could humor me with even a guesstimate answer.

Honestly I have no clue. Miss Gieco mentions above that he is going to check with some of his drag race friends. Good. I'm sure they will have some input on a maintenance schedule. I would also think that the drive shaft builders themselves (the link I posted above) have a recommended schedule.

I've raced Mountain Motor Pro Stock ( 825 Ci motors ) cars, we pull the drive shaft and trans after every run to service the clutch and check u joints and yoke.I never broke one in the Pro stock car but we now are required to have dual loop drive shaft tunnels because when they break it's nasty.

Just a thought, don't know if this will work in a boat application over the course of an hour long race plus test time but in some drag racing applications they use solid crosses, no rifle drilling for grease, you grease the caps and assemble. In a standard joint it is rifled drilled from end to end and then an additional passage is drilled to receive the zerk which makes weak areas?
