Mercury Prop WARNING!!
 

Mercury has issued a service bulletin regarding failures (throwing blades) on ALL Mercury props!!. Warranty period is one year only.
Even a drawing was issued as to where to look for surface blemishes or cracks (at the blade root)....
Seems now Merc is in the same boat as Hydromotives throwing blades.

Damn! I just bought two new Bravo 4 blade's :mad:

Yep, just got the bulletin today from Merc. Thanks Merc.:rolleyes:

Being a servicing center for propellers we have heard our share of client experiences. But you have to remember that some blade failures are due to improper finishing after they have left the manufacturers.

Bravo's don't like high X dimensions either...labbed or not.

Are you saying I can prevent those cracks by lab finishing my new props?

¤%{£{¤#%¤ I have agressive X-dim too, I'm toasted!!!

Threw a blade on a labbed 30 this fall. Mercury Racing replaced it without question.

They live....for a while...;)

I have to face it.

I'm going to spend the summer throwing Bravoblades :crazy:

There are some areas on a Bravo 1 prop that are just waiting for a crack to start. These areas can be quickly finished to reduce the possibility of a crack. The downside is that any work done to the props will void the warranty.

The reason that lab props sometimes last longer than stock is that these areas are usually finished through the lab finish process.

Could one of you that have received the bulletin with the drawing post the drawing for us. I would appreciate it.

Thanks,
Rick

Thanks jdnca1, :rolleyes: I feel MUCH better. ;)

May be I've to change my username to "Blade-thrower" after this summer :D

Crossing WAY too many bridges before you get there!Enjoy your boat ,IF something happens,then fix it,not before. You're welcome,Dr. Phil

What a nice guy! thanks Dr. Phil :)

Is this including ssm props

It is my understanding that it covers ALL props-
2.5 hp outboards clear up thru 525SC's...Alpha's, Bravo's, Mirage, etc- everything!!

Does anyone have a Phone # for Merc. service, or web address where one could review the service bulletin?

Is this a product safety bulletin to keep them from being sued? A blanket statement to cover their ass?

Do they also have a bulletin that says their engines and outdrives break too?

I lost a blade last year figured they would say tuff sh*t. Just bought another one:mad: I still have the old NEW prop. Its been over a year now though.

:confused: ... yeah, the funny thing is the defect causing the thrown/broken blades (per Merc bulletin) is due to casting voids in the blade root at the hub..... looks to me like "defective materials & workmanship" and should be covered.
There has to be a metalurgical test to "proof" castings before machining begins....??????

I cat scan all my props before they go on the shaft that way you know where all of the imperfections are. Rods and cranks get the CT scan also:D :D it is not rocket science.
