We have an 08 enzo Sv230 and do a little wakeskating and wakeboarding from time to time. Here is a short video of my daughter riding our wakeskate. (self built) Speed is probably around 18mph with tanks mostly empty. No switchblade. Boat interior is good and ours is holding up very well for being almost 10 years old. Stored indoors, climate controlled. https://www.youtube.com/watch?v=Iwlb2PuBM3E

The carpet we used has held up well. I am not aware of anything new or better. We used pressure treated 2x4s.

You might be prepared to replace the boards as well. We found some of ours were dry rotted. We used this carpet, some 3m 90 spray adhesive and stainless staples.

Managed to sneak in a few hours of smooth water fun before a breeze came up. Low 60s air and water here on the Columbia. Below; Alex making some turns. He usually prefers a skim style board. Definitely liking the new bag setup I installed this year.

LOL

Air is getting cooler but water is still nice here on the Columbia. Thankfully the smoke has cleared and we can get back to some riding.

I CNC'd a beaver tail and bolted to our fixed tab. I think it helped draw out our wave. I would be happy to machine another one if you like. Send me a PM.

Which is leaking, V-drive gear box or the transmission? The coupler bolts on our boat got loose and eventually fell out. That ruined the output shaft seal and the v-drive gear box started leaking oil. We replaced the coupler, prop shaft and packing sleeve. A local shop pulled the v-drive gear box, installed new bearings and seal (Walters assisted with parts), re-installed and did an alignment. I think that cost us about $1500. All good now.

Thanks and good question. Probably the biggest improvement was from the bags (weight) followed by the suck gate (which got rid of foamy lip). The beaver tail does help but I added it early on before the other mods. I'd be happy to CNC another one for someone to try out. (you pay material cost + shipping.) Our wave got a lot steeper with the weight so the tail probably helps draw it out a bit. We had one crew sit in the front which made the wave longer but not really any smaller. I'm thinking of placing the bag we normally run on the back seat in the bow next time we are out with less crew. ( we already have a V-shaped bow bag under the seats)

Had a chance to test the new bags today. Sitting a good 8" deeper in the water and the wave definitely got bigger. RPM's jumped up to 3000 (from 2700) to keep the boat going 10-11 mph. More gas was used.

Cut and installed some new aluminum channels and CNC'd a slip-in panel for the bottom half of the walkway to the bow. Used some VHB tape on the back of the channels to attach them more securely than the 3 #8 screws used at the factory. I made the panel out of Celtec expanded PVC instead of seaboard HDPE. It's lighter and a smidge thinner so doesn't need to be machined down to fit inside the channels. We keep the seats propped up when the boat is in storage so air can move through.

Bags are all in and plumbed! First photo is of starboard bag looking towards the back. The step/box covers the sideswipe valves. They are made of Celtec expanded PVC. A bulkhead comes forward and has a channel for the engine side panels. I CNC'd new ones to fit. Below is an earlier photo of one of the the custom inner bulkheads that go beside the front bags under the seats. Aluminum channel was attached to the lighter edge for the engine side panels. I re-used the hard tank brackets to attach the new bulkheads at the bottom. I glued blocks under the seats to fix the top of the bulkheads. Then fully carpeted the space. Below is the rear end of the port side under seat bulkhead with new divider panel beside the engine. I rebuilt the whole setup on both sides to fully constrain the bags on the inside. Below is the port bag installed showing new engine divider panel and vent lines. We now have 4 ballast fill pumps. This photo shows the OEM pump (above) which fill the rear bags and the new pump horizontal which fills the front bags which are tee'd together. I retained the original separate drain pumps. Just don't think we can keep from damaging the the reverse-able pumps by running them dry. Below. Each fill pump is connected to a dedicated port with ball valve. One of the pumps is used for the bow bag and bag we throw on the seat sometimes. We added a couple thru-hull fittings to vent and drain this bag.

We are CNCing a simple suck gate and offering it for $50. You purchase your own suction handle, cut out the handle part, drill some holes and mount. Or we can do all that for $100. Please contact us through DIYvan.com.

I had them 3D printed at Shapeways.com. I can make them publicly available via my shop there if you would like to purchase a set. I won't mark them up so you can get them at my cost. There is a right and a left and the price is $40 ea plus shipping. There are some little brackets I made by hand that you would have to fabricate. I used aluminum angle. Also have to seal the edge where it meets the boat with some 3M 4200 or 5200 adhesive. P.S. I made them available at our shop: https://www.shapeways.com/shops/impactproducts

Dearest H20king, Sorry to hear that you are having trouble figuring out the new interface. My request to you was friendly. I thought it would be fun to share some work I'm doing and provide some content for the Centurion Crew to enjoy. The flavor of your reply has me reconsidering. In the mean time... I contacted AEM to see if their filter would meet the flame (its not for sparks) arrestor requirement and will post their response. The OEM flame arrestor was loosely installed with two tiny screws on one side. I am pretty sure it would have blown off with a backfire so probably not adequate in the first place. I also had a look at the Oregon boating laws and the requirement is so old (1948) that it predates the electronic fuel injection that most all inboards have these days. I don't think its likely that these newer engines will backfire during normal operation. It has never happened on our boat. But I do remember it being a more frequent on boats with carburetors which were easy to flood if you pumped the gas too much. All the best, Hein

Thanks for the replies. I am aware of the requirement but would rather have clean air going into the engine. IMO, the AEM air cleaner will be fine for arresting sparks but I suppose I could get an SAE rated one from K&N. Not too keen on their performance and having to soak them in oil. Seems that would be more flammable than a dry filter. We had our boat inspected last year and the sheriff never lifted the engine cover. Your results may vary. h20king, Glad to hear your input but please don't quote all my photos if you want to reply. It' seems sort of redundant.

We think they were an improvement but can't compare to the silencers/mufflers you are considering. Did you watch the video on youtube? Finally getting some work done on the boat since I had a shoulder worked on. Custom bags to replace our tanks. Not looking forward to the plumbing/electrical work. We already have a bow bag and separate pump and two pumps and sprinkler valves for 6 hard tanks we had in back. Went with two bags one each side for more control than off the shelf enzon sacs. The rear ones are notched at the back to extend over the cover box I made for the sideswipe exhaust piping and valve. Bags sideswipe cover We have been running a suck gate and water is entering the vent so I machined some plugs that I will insert into the last 2 holes under the vent cover. The remaining two will allow plenty of air in. Also added a drain port and hose that will lead to the bilge so the carpet doesn't get soaked. plugs installed: drain port. I bonded the fitting in with 3M 5200. inside where hose to bilge will be attached Also replaced the spark arrestor with an air cleaner. PCV hose into the end. more progress coming up...

I think it helped. Want me to machine one for you?

Seek out some 12mm Seaboard HDPE. That's what they used for the seat backs throughout our SV233. We don't have a bow filler either but pretty sure that's what it would have on the back. We stock it in grey and black. How big is the piece? If you give me exact dimensions then I could CNC it for you.

annual maintenance item.

Some November fun on the Columbia:

Sneaking in another day on the Columbia. Our trusty driver. Hood River Bridge:

We added some 3D printed cowls to our sideswipe which reduced the noise level. After using them all summer, we have concluded that they have helped clear up the air for the rider as well. http://www.centurioncrew.com/index.php/topic/11066-2008-enzo-sv230-projects/#entry147654
