Water Cooled Shaft Seal?

Recommended Posts

ds53652

Hi,

I've received a lot of great input from everyone here. In a previous thread, everyone told me to order the boat with the Water Cooled Shaft Seal option. When I was discussing options with the dealer, he emphatically told me NOT to get this option and that his mechanics hate it.

Why is that? Is it something that eliminates maintenance ($) for them or something?

Thanks in advance (again) for everyone's input.

I don't know jack about them and I don't own a boat with one but, from what I can tell, hardly anyone has one and it's just something else to go wrong/complicate something that doesn't need complicating-up.

My dealer told me that his mechanics love it - makes maintennance much easier.

Also, packed seals have a tendency to drip - if you leave your boat in the water, it will

gather water in the bilge ( not enough to sink, just to get wet ). Not a big deal, but I

like my bilge to be dry, and know that if it is wet down there, I should start looking for

a problem, that's why I went with it. Just my 2cw...

They are the shiz as an owner anyways, don't have to adjust them and never had a problem with one in hundreds of hours of use. It's actually a very commmon option on malibu's.

I have an 06 Response lxi......order it and forget about it.....they work great

I am not sure why your dealer would be so negative about it

I would think that if it was a problem,then Malibu would not offer them in the first place due to potential warranty issues

Love the one in my LSV.

It is similar to seal designes we use where we blow air across knife seals to keep oil from coming through from the other side.

This is the same logic, as by pushing water from the inside you avoid any leakage from the outside.

I too have no idea why dealer would say that unless he was interested in charging you every few years to repack the stuffing box which you DON'T have to do with the dripless. Packing is a MUCH bigger PITA.

Thnx everyone for your input! I've asked my dealer to explain to me why they do not recommend this.

I would love to hear from some of the dealers on this forum as well.

Thanks again everyone!

They basically said it was just another thing that could fail and if it did fail, it would allow a pretty quick in-rush of water. The mechanic also stated that in 4-5 years, the seal will require replacement which would be about 5-6 hours of labor. He also stated that they maintain the packing one as part of their winterization/summarization packages. And to replace it however many years down the road would only be about 1 hr of labor.

I'm still confused...

The packing gland has to be adjusted every year or it will let to much water in the boat, he's saying they do that during winterization (hopefully during de-winterization). There is no adjustment of the dripless unit but he's telling you that you will be replacing it in 4-5 years.

We put one on just about every one of the boats we order, it's a no brainier, great option to have on your boat.

Never heard of one failing, all of my dealers' boats come with, and if they're going to charge you 5-6 hours of labor if it did, find another dealer. I installed one in less time than that. In other words, I put the whole thing in, not just replaced seals in less time. Furthermore, how is a dealer going to adjust your packing with it being out of the water for winterization purposes? That makes no sense.

It only been an option since 2006 so being that this is now 2010, I guess we will find out later this year Tease.gifTease2.gif

Seems like it hasn't been an option long enough to make a statement that it will need replacement after 4-5 years. Sounds like a guess to me.

We haven't had to replace one yet, I would think they would last a long time the way they are built. We should get Eric from OJ to chime in since he builds them.

FYI, against my dealer and the dealer's mechanic's recomendations, I went with the Water Cooled Shaft Seal.

Thanks for all of the input everyone!

We have been running the XPC Seal System on other MFG'S boats since 2003 with very good success. The system has worked very well on the Malibu line since it was introduced in 2006. The only issue that I have seen with a system, from any builder, is the shaft not being aligned. This issue will be a problem on any sealing system, rope packing or our double lip seals. So, with good alignment the system should work for many years without an issue. The original test boat for the system, which we put 1,000 hours on in 20002, is still running strong. This system was tested with no water to the housing. Replacing the seal in the event it needs replacing is as easy as repacking the old style system. The lip seal is pressed into the housing and retained with a clip. Simply remove the clip, pop the old seal out and install the new seal and clip. Trim the "hump" hose to insure the seals ride on a clean and smooth portion of the shaft and you're done.

Feel free to give me a call if anyone has more questions. Hope this helps.

Eric
