I had a Donzi Z33 that had a short, it would cut out an engine at any time (I found it was an exposed ignition wire grounding on the intake) and it always just coasted, this was a very wide boat at 9'3" This is interesting, it looks like it is safe to have a failer at these speeds. Like a tire.... my drivers front blew at 80 and it just coasted to a stop, if I had let go of the wheel it would have pulled but it was not shaking or hard to hold. Like said, anything can happen and it is usually a combination of things that cause an accident, like maybe turning sharp when this happened, or in big waves jumping and it came down on one and hooked, who knows but you always hear how a spin out was due to a drive or engine failure...maybe that is just a standard excuse for driver error (now don't start, this is just my opinion). This thread seems to show it is a non event. How about at higher speeds? Say 150+. I always worried about this when running at 70 or so in the AT, it was much narrower and I wondered if this would matter, I guess the chances are good nothing will happen.

I broke a shaft on the drive and lost the prop at 103 MPH. The single engine cat did not do anything funny; it just slowed down and stopped.

Racers area will get you more info as far as drive failures........

I'd ask there since the flips and spins seem to be caused by drive failures more often at WOT.

Just an idea.

Had the port engine prop shaft break at 105+mph in a 22' Talon tunnel with twin 2.5's on nitrous. It took a hard left but I was able to maintain control and straighten her out as it slowed. Scariest surprise I ever experienced and reinforced my belief in always wearing a life vest when running hard. Turned out an internal flaw in the prop shaft propagated out as a fatigue crack from many hours of running surface piercing clever props. Now there is a really nice Mazco prop laying on the bottom of the Mississippi River...

I have lost a motor at 100+, no big deal, as everyone has stated. If a motor locks up, the next weakest link is suppose to break so that the prop can still rotate. If something happened and the prop was not allowed to spin, I think this could be a potentially serious probablem.

That's what I am thinking if the motor puked and locked up stopping the prop or the drive doing the same thing.Wouldn't it turn hard ?

Just think if a V bottom or Cat say at 150MPH and the prop locks up.I would think its going to turn.


I wonder if these boats that do the record runs like Fountain and Outerlimits at 170MPH and Dave Scott's boat at 200MPH would have something if it breaks that would let the prop spin like a ratchet??? I know the jut boat guys have a ratcheting pump in case of engine failure.

Just curios and thinking what if
