A month ago, I lost a universal at full chat, causing the destruction of my AQ in spectacular fashion. Eh, being an ex-drag racer, it happens. Replaced it, and on the maiden voyage, about 15 miles in - again at high rpm - heard the death knell of another AQ. Took it apart, and on a whim looked at the engine output shaft. It is bent to the tune of 1/4" vertical runout. Went to the local marine consignment store, and, very luckily, found an intermediate housing assembly- My GT21 uses the 6" extension one. I guess I'm pulling the motor, good thing it's a long weekend!

Failure #1

Tow of shame

The culprit the second time, I assume it bent during the first, ahem, incident:

I see you're practicing the fine art of rope pushing!
In the past, some here have taken it to a whole new level.
We've all practiced at times, the last time, I pushed a 'toon boat in.

Finding the intermediate shaft at a local consignment store has to have some real luck involved. :yes:
Why did the intermediate shaft runout cause the upper outdrive gears to be destroyed the second time? Was there not an extreme vibration from the 1/4" runout even in neutral?
Who has the really nice looking yellow barrel back?

I'm thinking that when the first ujoint lost a cap, it jammed and bent the shaft (some force involved to do that!) along with destruction of the upper and intermediate housings, and snapping the intermediate drive shaft.
I hope runout caused the upper gears to break the second time, it was nearly immediate.
I'll find out next week if I found the root cause!
