B.O.A.T. - propeller shaft
2 Attachment(s)
Anyone have any idea how this could happen? Don't think I hit anything, didn't have any weird vibrations before. Just cruising along and a loud bang. :banghead:
Doesn't appear that anything is bent at all. |
You mean the prop along with the part of the shaft came clean off? Whoa...
|
Past impact + fatigue or bad shaft + fatigue.
I had a similar occurrence with a rudder. |
looking at the picture it looks like your shaft is way out of alignment
see how it is way over to the left side of the strut Harmonics can build up from a shaft that is WAY out of alignment and break the shaft |
Camera angle distortion might be misleading, but the cutlass bearing confirms the misalignment. Look at how it is compressed on the left side and not on the right.
|
I'm thinking we hit a little something earlier in the day, enough to throw it out of alignment, and a little hard running on it eventually made it break off.
Hope this doesn't take forever to get fixed. |
yep that will do it

Get the alignment fixed or it will happen again. |
I had the same thing happen... When I bought the boat no signs, but the previous owner hit something, there was just enough fatigue that the shaft was in a small bind and it finally sheered off...LUCKILY mine did it above the shaft strut, and I didnt loose my prop, because when it slid back the prop hit the Rudder and it was still hanging in the shaft strut
