Broken Bravo drive question
 

Pretty sure a drive let go yesterday. At first I though it was a coupler but could see the spline shat from the drive still spinning but no response from the drive when throttle was advanced.

Idled home on one engine/drive. Back at the dock the drive did engage and have forward/reverse at idle speed. Is it common to have drive at idle but it degrades as power is added ? Like the drive is slipping ?

Normally when a drive starts to come apart you hear it making noise. I'd look alittle closer at the engine coupler, check to see if you see any rubber shavings near the back of the motor by the bellhousing....

Sorry for your bad luck, but if you need a drive I do have one for sale, and I have left or right hand.

Re: Broken Bravo drive question
 

Sounds like a engine coupler to me. Pull motor time.

Re: Broken Bravo drive question
 

Could be a shifting problem also.. do a search on shift problems and check the threads, the info was posted some time back.. to help you determine if it is a shifting problem..

Re: Broken Bravo drive question
 

Could it be the hub on the propeller?
That sure would be a simpler fix.
They'll fail just like you described, you can idle in fwd or reverse, just can't give them any power.

Good luck.

Sure it could be the hub, but same as with the coupler normally when they start to go they slip alot like a clutch in a car if you accel slowly they will grab a little. pull boat out of the water put it in gear and try to turn the prop.

what area are you in????
if you have anyquestions give me a call or email me

Re: Broken Bravo drive question
 

Sounds like the same problem i had another boat and turned out to be the coupler.cheaper to fix that then replace drive.

Thanks everyone. I'm putting it on the trailer tonight and will report back.

Turned out it was a spun prop hub.

cool glad to hear thats all it was!!!! :evilb:

Re: Broken Bravo drive question
 

just had drive rebuilt and drive shower added
im noticeing what seems like slip going from 3000
to 4000 rpm seems like cavitation but maybe my hub?
is the hub in the prop or is it that plastic insert on the bravo
that is supposed to break in case of impact

Re: Broken Bravo drive question
 

It would be unlikely that anything in a Bravo drivetrain could slip at that rpm/load without being destoyed almost instantly. Cavitation is more likely.

Re: Broken Bravo drive question
 

I have heard of drive shower water pickups interfering with the water flow and causing cavitation but mostly when trying to get on plane.

LennyK,
Some props have fixed rigid hubs and others are bonded with rubber. Mine was a bonded rubber hub that sheared and caused the slippage.
