POD uppers resealed, Ceramic coated shafts installed

No skegs?

 

We run in shallow water here on south shore of long island. Id rather lose a skeg then the pod. To each their own.
I do make sure the pins are red loctited in.

 

So the skegs are bolted on?

 

Re ceramic...what did the Cummins tech think of the ceramic solution? Re the skegs: There are updated skegs that don't fall off. (So Mercury says.) Don't know if you had the old style. My 2013 Sabre still has the old ones. BTW, your pic of your prop damage looks like blade failure to me. This failure is more common than you would expect. The previous owner of my boat had the exact same issue and I have heard of others experiencing this as well.

 

Same...shiny edge or bright metal was what was left when it let go

 

No they are pinned in place with these

 

That seems just a little problematic

 

How do you get under there to change props on the water?

 

I don’t think so.
Shiny smooth surface is pre existing defect and rough dull surface is sudden failure.

 

Why?

 

They are roll pins... so the pin collapses in the hole. Each hole in the skeg and each hole in the main body have a tolerance on size and location. So not all holes are holding equally... to me it would be something that could be knocked off easily.
Would be interested what the upgrade was...someone mentioned

 

Corrosion dulls or oxidizes the surface of the crack...what’s left is raw metal...in the case of stainless, bronze, steel it’s bright

 

I don’t understand if it’s a known issue that the pins vibrate loose causing the skegs to fall off and cause substantial damage. Why wouldn’t they use some sort of other fastener that can’t it vibrate loose. I understand that it needs to be able to break away in case of sticking something but they could still accomplish that using bolts and nuts that sheer away?

 

the roll pins along with the loctite and different attaching methods are the upgrade

 

I have a boat next to me in storage that has Volvo pods where the props point forward... I took a good look at that setup and thought no matter what you hit it was going to be expensive.
Mercury it seems wants to sacrifice the skeg and props instead of losing the pod if the hit is low... either way there is a lot of money hanging down there

 

you can see the difference between old and new in the attached service bulletin.
