2008 Enzo SV230 projects

[Hein 63]

 

 

We've owned this boat for about a year and we are hooked on wake surfing. So I've been making some improvements and have ambitions to do more. Who doesn't like a project, anyway...

 

Last summer I added 2 more hard tanks in the back on top of the stock hard tanks. Probably should have went with Enzo sacs but would have to fab a better enclosure for those. Additional hard tanks were easier at the time. Also added a bow bag (with vent and a drain pump) and another pump to fill it and the bag we put on the back seats.

 

The extra hard tanks are plumbed in parallel with the stock tanks. I added dedicated drain pumps to the new tanks this spring so they would drain quicker.

Spruced up the wiring for the sound system, reconnected the tower speakers and added a 12" Polk sub to the kick panel. Also added a small digital volt meter (above heater vent) so I can see what the battery voltage is when I power up with the Perko switch. I cut the kick panel into two pieces so there is a smaller piece on the left that can be removed to access the batteries.

Oil filter relocation:

 

5/8" ID hoses with 150 degree and 90 degree AN ends.

 

engine connections:

 

filter mounted to front starboard engine mount.

I designed some cowls for the side swipe ports to help reduce exhaust noise. These are 3D printed by Shapeways. We tried version 1 last year but they fell off because I hurriedly attached them with silicon sealant. The noise was less but we didn't get a chance to fully test with them. Version 2 below is attached internally with small angle brackets held on by the screws in the sideswipe bezel. And then the perimeter is sealed with urethane adhesive. Hopefully they'll stay put this time so we can make a proper evaluation. I am hoping these will keep the exhaust gasses submerged so we won't have switch the exhaust to just one side.

WOW! Other than the hard tanks, I'd say you've done a bang up job on the mods! Keep us posted on the Sideswipe baffles for sure! And ... ditch those hard tanks and get Enzo sacks. You'll be glad you did! What's this about an enclosure for them??? The only thing you should need to do is reinforce the locker/engine dividers. And that's even negligible.

[Hein 63]

Thanks and agree that bags are a needed upgrade. Our dividers would need some help for sure. There is quite a bit of sharp stuff (fiberglass edges, etc.) where the bags would go so would need to sort that out.

Awesome!!!!! Solid work!

 

Those Enzo sacs are pretty tough!!! It should be minimal work

[Hein 63]

Thanks for the info regarding the Enzo sacs. Being new to wake surfing boats, we didn't realize how much innovation is being applied to improving the size and shape of the wake. I think it's awesome! Adding ballast is straight forward enough. We ride on the Columbia River with barge traffic so would like to keep the rub rail mostly dry and prefer to be more or less evenly weighted.

 

So in attempt to draw the wave out a bit I added a 'beaver' tail to the OEM fixed trim plate. It's CNC'd to fit over the OEM tab and attached with two rows of 1/4-20 bolts. There was no real reason to flare it out other than to not have it rectangular. Material is 1/2" HDPE (Seaboard). It's was on there all last season. There is a little bit of flex in it.

 

 

 

Our wave on a good day.

How did the second set of cowls for the side swipe turn out? Did they cut back on the exhaust noise?

[Hein 63]

Noise results for the cowl were good but not sure about whether there was any improvement to exhaust smell for the rider. We still ran with the sideswipe set to the opposite side as the rider. We'll leave them on and do some more evaluation. Here is a video while surfing at about 11 mph.

 

And one at the dock at idle.

(Before the ballast tanks were full. With tanks full the exhaust is underwater.)

If you were interested, FAE does make a Sideswipe replacement muffler

They state it will also free up locker space...more room for ballast

[Transporter 1]

Wonder what cost is?

[gravity12 83]

That beaver tail has me interested.  Did it work as you expected?

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

Hein, I have the side swipe as well (04 cyclone)  and am looking for ways to decrease the noise. How effective was your cover?   I've been looking at these: 

Slip-in silencer

Or 

Exhaust baffle

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...

Hein, I'm just following up with your cowls...did you make them yourself or buy them?

Spark arrestor is there for a reason and are required by law in Oregon. When you get stopped for a inspection they check the spark arrestor and verify it's clean 

[Jake707 171]

Same in CA. Hell they check my dirt bikes for spark arrestors every time. 

[Hein 63]

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.
