Broken Shafts on Carver

The shafts that connect the gear to the propellor? Where did they break? Were the props recently changed or removed/replaced? What other info do you have?

I think so. I've boated for 35 years in many different boars and never broken a shaft. Come to think of it, I've never herd of a broken shat. Bent but never broken. I believe faulty metal.

These guys lost their prop and shaft: http://www.stuff.co.nz/dominion-post/news/9367749/Ferry-out-of-action-after-losing-propeller

Has the drivetrain ever been aligned?

That is what I was trying to demonstrate and that was the only one I could think of off the top of my head. The prop was recovered and reused in that case too.

Without further information this is just a teaser post or someone trying to slant Carver.

Come on Ernie give us enough info to help you.

How often have you seen the same boat break both shafts in less than 300 hours?

I doubt that the OP's boat has hit many deadheads.

I also am in the camp that this situation is very far from normal. The only plausible connection for having both shafts break in 300 hours (provided they're properly sized and the vessel has not incurred major damage), is that either the keyways weren't fitted properly, the propellors were not installed properly, or the alignment is seriously off.
