POD uppers resealed, Ceramic coated shafts installed

Too much room for error, in my opinion. Plus if you lose a blade like I did, you have a 75% chance it damages the hull. I had a nice ding on my keel afterward.
 
You guys are braver than me, but I don't ever plan to get under my boat unless it's on land!
It’s not as scary as it seems as long as the water is deep enough.
 
Launched today with my new ceramic shafts. All went well! Photos in chronological order. Yes I went for a 2nd ride and anchored out after stopping at my slip for a few hours.

James. How do you like your 470? Considering upgrading. Positives and Negatives? Also how has your experience with Zeuss drives been in terms of reliability? Thanks!
 
The Cummins mechanic was very impressed and excited at the prospect of this becoming a solution he could now recommend to other clients in the same position.

I know about those updated skegs but I'm still dubious and have PTSD from that Labor Day weekend lost. When the props turn they come within about .75 inch of the skegs and those things are some serious hunks of metal. Maybe it was prop failure, but when I saw that skeg missing and the other side hanging on by a thread.....well let's say I didn't think it was coincidence. I grabbed the port skeg and wripped it off and never went back to them.

Heck, look at Volvo IPS pods, those props are forward facing and totally exposed and that's becoming the pod of the future. Makes you wonder why they even have a skeg, with it being aft of the props. And ZF pods for Yanmars have no skeg at all.

The skeg on the Volvo pod extends well below the prop arc. So there is a solid hunk of metal that is going to contact the bottom well before the prop.

I suppose it also provides some small "rudder" effect, and if we really want to overthink it there may also be some tip turbulence mitigation (re passenger aircraft with vertical winglet tips).

Love my 470. Going on my 8th season with it so that alone should say something. Longest I’ve ever owned a boat by 2X. Dislike canvas and not having sliding glass door but I do like driving with the aft wide open. I added custom 90 degree down canvas which keeps heat and a/c in when needed and with great aft visibility; the factory canvas offers terrible visibility. Dislike the fact the helm seats don’t swivel like they do on the 48/50 and 510. Like the aft sunpad with the backrests that swing open, we use it a lot. She handles great, can turn 180 degrees in 2 boat-lengths. You can see the horizon out the sunroof window and the engines don’t give up RPM in the meantime. I added the hydraulic swim platform, but I suggest buying one with it already. I ditched the dinghy and now carry a Yamaha VX on it.

Knock wood I’ve had better luck with my pods and transmissions than some others. I have 1430 original hours on all. I’m crazy about PM and spare no expense to keep myself on the water to maximize a short season and busy work schedule. I check all three pod fluids before I leave the dock and after I return. I know guys who never do that. One pod owner told me MarineMax checks all that for him when he launches in the spring. He’s had problems!

What year are you looking at?
 
Per my previous post, Cummins came today to lower both my pods and reseal all seals on my upper pods as well as the king pin plates. All looked great to him. He resealed them, re-hung them and also installed my newly ceramic-coated prop shafts with new seals. All is back together and the boat is ready to launch. Some photos of the day.

Outer shaft coated. (The top is just electrical tape to protect the threads in shipping)

Upper POD with King Pin Plate removed:

This is one of the pods in a custom made lift. He locks it into place and wheels it away from boat.

And here's everything all put back together. Note the green film on outside of pod. That's gear lube leaking out from the top, which is why I had them resealed.

The reason why your skegs fall off is because you need to apply Green loctite 271 to the base of the skeg and dowel pins too. Its in the manual. Never had one come loose on me an I do alot of pods down here in Florida. Just words of wisdom.
 
If your prop blade fell off from non impact Mercury will cover a new set from a casting issue. If it was from impact then you are out of luck.

The trouble is, how would I prove it was non-impact?

Before I decided to run without them, I asked a tried and true POD expert. I confirmed with him there is absolutely no rudder effect or performance improvement that the skegs add. If you Google "ZF Pods" you'll see those don't have any skegs at all, which adds credibility to his assertion. Plus I've run my boat with both skegs, one skeg, and no skegs and I can tell you I've not discerned any difference at all. In the Zeus pod, the skegs' sole purpose is to protect the props and they're designed to break off to help protect the pod itself by absorbing some of the shock if the grounding is minor. Contrast that to IPS skegs which may or may not protect the props depending on the contour of the sea floor and probably offer no protection against floating debris. Also the IPS skegs are not "break-away" so they offer no impact absorption to help you keep from losing the pod entirely.
