IPS Corrosion

[SkipperMarv]

I was under the impression that the Volvo IPS was using metals that resested fouling and corrosion, but spotted this at the weekend.

I think someone needs new props /forums/images/graemlins/ooo.gif

Ooops.

Have you got the owner's permission to publish these photos? /forums/images/graemlins/grin.gif

Is that the boat "parked" up at RK?

Couldn't possibly comment /forums/images/graemlins/wink.gif

It is indeed, not looking too good is it?

That might have let the "Cat out of the bag" on such a new and unseasoned technology.

I like the idea of IPS but had decided to wait a few years so see how it all pans out in practice. Allow time for sufficient maintenance experience and other possible issue come to light over time, before I invest in something who's TCO has not yet been proven. There are always risks with innovation, but I'd rather not fund the early 1st generation's evolution cycle.

The unit itself looks okay, but those props aren't too happy.

You may need permission from both the boat owner and because the gravel/earth is included also the owner of that said gravel/earth. I do not think anyone can be said to own the air between the camera lens and the props that you photographed through, albeit without permission, so you should be OK on that aspect. /forums/images/graemlins/smile.gif

How old is this boat? Where anodes evident?

It seems that boat manufacturers have decided IPS is the way forward. Whether we like it or not, most new boats to the market now seem to have it as standard.

Personally, I'm not sure about IPS and would like to see how it compares with the new Zeus system from Brunswick, which has the props facing the "right" way, and looks less exposed to the crap that floats round our shores.

The unit is mainly ok but there are still some areas of quite deep pitting on it too, but the props ...........

I think they are only good for ornaments

No! I took pictures of it the other day as well. Not quite as close as you got though.

Not sure sure that is necessarily a problem with the IPS unit itself, looks more like an electrolysis problem which can happen on any boat irrespective of the drive configuration. I have a boat at the moment only two years old that looks very similar which has been traced to a faulty earth in the boat, nothing to do with the drive units.

Thanks - I've decided it's time for start reversing the years - I'll be 50 again in 2020!!

IPS / Shaft/ Leg /Outboard. Don,t matter.

Taint an "IPS" prob. Tiss the usual prob. Different types of metal close or in the "Oggin"
Depends were your at .
Swinging mooring, changed the anodes every 2 Years.
In the Marina twice a year or so.
Depending which part of the Marina and who I was berthed next to!
Can,t see why IPS will be any better or worse than any other propulsion method /forums/images/graemlins/confused.gif

My point indeed, the metal and components don't know their IPS/ Outrive or shaft they just react to the enviroment they are in.

I doubt SS props would have looked like that. Although they would have caused more of the drive unit to dissolve!

 

[DAKA]

Could they make the whole leg of stainless ?

Weight isnt as much of an issue with outdrives(best place to put weight).
Could be thinner than brass/monkey metal mix.

Cost of raw materials isnt likely to be significant by the time the 'marine load' is added.

 

[tico]

Yeah, but cost of a pair of Ally props ~£300
How much for a pair of IPS Nibral ones?? (gulp)
