Thank you for the information BigCat. That is pretty closed to my measurements. Yours is slightly bigger than what I had but it should fit just fine. I would like to hear your measurements for the starboard side Troy or Bigcat. Thanks again

Its the engine compartment blower 4" flexible black pipe on the starboard side and on the port side its the same type of pipe that is just open into the engine bay. Not really sure where it even comes from. I will have to look when I get home. I think it goes to the battery compartment. I could probably just move it or shorten it up to get out of the way.

What was the final weight of the sac when filled completely?

Yeah I would like them measurements. How did you handle that exhaust tube that runs across the top of the locker?

Im looking to upgrade my ballast. I have read other posts on here about a custom avy sac. I have a 2010 centurion avalanche C4 and wanted to know if anyone had the measurements for this sac or who to contact that might have this info. I couldnt find it on any forum. Was just going to do the port side for now. I called wakemakers and they did not have the measurements. I took my own measurements but I wanted to compare with someone who has this sac before spending the $700. They said the enzo sac would not fit. Thank you

I have a 2010 Centurion Avalanche C4 PCM EX343 5.7L. After a day on the water pulling tubes and surfing. On the way back to the dock. I had the low engine oil pressure alarm come in. I checked the oil and I was down 1.5 - 2 quarts. I added oil for next time out. Ive never had to add oil before during the season. The next time I took the boat out. The oil alarm never came back in but now every 5 min or so I get a service required alarm coming in. The boat runs perfectly from what I can tell. I changed out the oil sending unit but that did not clear the service alarm. It may be a knock sensor and ill try that next. After another day on the water of pulling tubes. I was down almost another quart of oil. I checked the engine and bilge area and could not find any leaks. I did notice around the oil fill tube there was oil that had sprayed onto the engine cover. And the only other thing I noticed was after pulling the tube for a while. I could see a little white exhaust smoke. I guess Im just looking for some help diagnosing this issue or these seperate issues before taking it 3 hours away to a dealership to look further. Any help would be much appreciated.

Thanks for the reply’s. I contacted the dealer I bought it off and they ordered me one from commercial sewing. Was disappointed I could only get it in light grey and not black. They said they didn’t do black because of staining of the seats. Haven’t put it on yet but it looks nice. It comes with the pull tight system. Hope it works better than the poles.

My email is bradmebert@yahoo.com. Cory said he didn’t have a pattern for the ‘10 centurion avalanche and suggested a couple different places to have it done. I would still like to see the photos of yours.

I’m in need of a new cover for my ‘10 Centurion Avalanche C4. I contacted Cory from evolution and he does not have a pattern. He suggested ski boat covers.com but I wasn’t impressed by the pictures on their website. Cover craft.com looked pretty nice but don’t know much about the company. Sewlong.com looked really nice but very expensive. I want something similar to the factory one I have but like the looks of the evolution covers. I also like the idea of no poles to deal with. Anyone have any suggestions that has had a new cover made for them? Thanks Brad

I just sent the email to Cory about my ‘10 Avy. How much was your cover and how long did it take to receive? I would also like to see your pictures.

I’ve not greased the rudder. I just recently purchased this boat. I’ll give that a try and see what happens. It pulls right when the ballast is empty. It makes sense that the rudder is moving because it doesn’t do it immediately after letting go of the steering wheel and it’s not like I have to hold it to the left to get it to track straight

I notice a clicking while steering. It is really noticeable when full of ballast but can still feel it sometimes when ballast is empty. The boat also will track straight for like 3 seconds then pull hard right if I let go of the steering wheel. Are these things normal on the Avy or should I look into this?

Everything is back together. No leakage at all now. No vibration at all. So far so good. I left it in the water on the dock. Still makes me nervous that its going to sink. lol. I could do a full write up if anyone needs help with changing this part out. The scariest part was jacking my boat up from the back end to remove the rudder. I only had a floor jack. Wish I had 2 stands to jack it up from the hooks in the back but I had to go with what I had.

It rained all day today so I didn't get a chance to work on it. Ill start again tomorrow. The write ups i read where not the same for my Avy. The signs you need to replace it are the seal is leaking filling up the hull with water, kicking your bilge pump on every 25 minutes. I just bought this boat and this was the first time I had it on the water. I put it on the dock and came back a couple hours later and seen the bilge pump was running. Then I looked in the engine compartment and I could see ripples of water under the v-drive. Didn't notice this on the test drive but never thought too look. Lesson learned.

The old shaft seal was stuck on there pretty good. I removed the clamps and used a razor blade to cut the old rubber so I could attempt to remove the old seal. Then I used a gear puller to remove the coupler from the shaft. Then I removed the prop from the shaft using a acme prop puller. Next time I will leave the prop nut on there until the prop is free. I didnt do this and the prop went flying off and dented my prop. Had to beat it back out. Hope it doesnt cause me any issues. The shaft still does not come out far enough to remove the old seal. Ill have to remove the rudder tomorrow.
