08 Centurion Avy C4 - Bilge pump question

[dlee434 0]

I have a new-to-me Avy C4 I got last week and put it in the water for the first time yesterday. I noticed that the bilge bump kept coming on every 20 minutes or so, shooting out the same amount of water each time (20-30 seconds). We parked the boat on the water and sat for about an hour and I turned the pump on again, shot out the same amount of water. Waited about 10 more minutes, then turned it on again and it shot out the same amount yet again. I checked the plug under the back seat every 30 mins or so, and it seemed to have the same amount of water in it constantly and didn't appear to fluctuate.

The previous owner said he only had the issue when he had his ballast bags full, something about that type of bag having a coupling leak that needed to be fixed on the bag I believe. I didn't fill the bags up the entire time we were on it though, so I don't think that is the issue.

I have seen some post about the shaft packing on other boats possibly being the culprit, but I couldn't find anything on this particular model. Any help or tips you guys could post would be greatly appreciated.

If it is your shaft packing that is leaking too much you may find this old thread helpful....if nothing more for a good laugh!

It was definitely the shaft leaking, check out the video above.

Here is another link I found that goes over the same thing.

 

 

Looks like I am a candidate for the PSS install. As someone with decent mechanical experience on cars, is this a job that I should be able to do without pulling the vdrive? From @h20king's thread, it looks like I can do it but I am not sure of his boat model. I called a few places this morning to get estimates and am waiting to receive a call back from the mechanics to go into more detail about my issue. A hurricane is about to hit us on the east coast so I guess it is a good time to do it.

I pulled my v-drive and did everything myself (2008 Avy).  Difficult but not impossible.  If you're good with automotive, I think you could do the swap your self.

I did mine without pulling the Vdrive, used the Glide bearing kit and did the cutlass bearings at the same time. It was pretty much blind work all done with feel but it only took an hour or so. The hardest part was alignment of the shaft which I believe was what caused the bearings to take a dump. really a piece of cake other than not really being able to see what you are doing.

I did mine over the winter, the shaft had a grove in it so i also replaced it, had a minute leak on the transmission v-drive gearbox input shaft so i also pulled it out and replaced it to. i pulled the seal out searched for a new one to find out they wanted to sale a whole gasket kit, luckily i was able to read the numbers off of the old seal and cross reference to another brand. I could of had it done in a day if i didn't keep getting sidetracked.
