Impact damage
 

Would impact damage cause the u-joint coupler to explode on a bravo boat?

I would think it would break a lot of other stuff first, like the engine coupler or drive gears.

Well, that too. Upper & lower gear set both have teeth missing.

what does the prop and prop shaft look like, you may have suffered a upper failure causing the other damage, is the input shaft twisted?

There is a impact point on the leading edge of the nosecone & skeg along with a nice blue transfer line, a spot & the blue on the mid-section where whatever kicked up into it.
Everything else looks to be ok.

if it hit hard enough to knock the drive up at a high rpm, it could have caused the u-joint assy to fail, but not sure on the gears, I would have expected prop damage. what speed and rpm where you at when it failed?

About 45-50 mph, 3000-3500 rpm or so. Hadn't even hot-rodded it yet for the year. It was the 1st outing, just warming up the oil.

well I would say that if everything was fine til then, it was probably impact damage.

Everything was just fine. Just serviced the drives. Oil was clean & clear and no "hair" on the magnets, top nor bottom. Both drives had fresh gears & bearings last season too.

got insurance, sounds like impact.
good luck

Jason sorry to hear of your mishap.

How bad was the prop damaged??? At the RPM you were at the torque is at its peak, so if upon striking something and the prop momentarily locked up, it would break some gears and possibly break the driveshaft.

I broke an upper gear tooth off which locked the drive for a split second and it twisted the input shaft 90 degrees. I was at 3500 rpm which is my peak torque.

Not a fun thing that's for sure. At least you got yours wet. more month for me :mad:
