Other bob snapped drive shaft

[stg5685]

like the title says snapped the driveshaft on my bob it happened when my steering cable broke and i was riding in compensating for the steering cable. is this because of the broken steering cable? could it be pump shimming? and last where the best place for a new one and do they make a stronger aftermarket one?

jetmaniac has them or buy oem www.greateryamaha.com or www.kawasakipartsnation.com

dont think the shaft had anything to do with the cable

Holy Jesus did I just read $389 for a OEM driveshaft?

interesting. did it like snap in half? towards the pump or up towards the midshaft. I'm curious how the bob contributed to the break.

I'm running a jetmainiac driveshaft with no issues for over a year now.

Did you make sure that the drive shaft wasn't binding against the mid shaft when assembling the ski? Pump shimming is super critical as it could cause some drive train damage.

We've also seen quite a few Aftermarket drive shafts and a few OEM drive shafts in a variety of hulls snap 'just because', you might be in that category if everything is set up and shimmed right.

did this happen in your bob too?

my buddies drive line snapped in his rickter and it was lined up perfectly,he just did a roll and when he hit the water it snapped.

It can happen in any hull, I HIGHLY doubt the hull was the culprit.
I had it happen with my old wammer ski. Stuff breaks

Alignment is critical, but the tapered shafts tend to break right in front of the impeller where they are 'fusion?' welded.

Also driveshafts that are out of true because of shipping/handling are more likely to break.

I've seen driveshafts snap flush with the impeller many many times, major bummer though!

 

[chriselmore_1]

It was caused because of a faulty layup in your bob jk

did you shim the pump so that it stays centered in the bulk head? you cant just get it in the middle, slap on the mid shaft and then tighten down the pump.

Here's one out of a Super Jet that was just posted on FB - snapped in the same spot as yours.
