Hi all, I've picked up a second hand sesitec system 2.0 and I'm slowly building a cable park. Sesitec have been very slow to reply to my emails and I figured surely we'd have some people in the brains trust here on Wakeworld who might be able to help! Just looking to find out how I should service the motor, particularly gear oils and motor oils, and would gladly love any other advice you can give. It was all working when I packed it down but it all looked like it needed some TLC before I put it up,

I've excavated the lake and hope to dig/pour the anchors in the next week or 2. If anyone is interested I'm documenting the build (I'm not a very handy person so I'll be as descriptive as possible).


Thanks for your help in advance!

I can't help on the Sesitec information, but I am definitely subscribing to your build.

As a civil engineer and a wakeboarder I've envisioned cable parks on all sorts of plots of land I've driven by, but based on the back of the napkin cost estimate couldn't justify one for myself and the cost of land in the Northeast.

I'm interested in following your build and wish you luck.

Following as well. Are you going to build your own features or source them?

Both, plus I am going to rebuild some of the old features that were at the park I bought - the kickers are pretty stuffed.

So starting from the beginning - I had a swamp in the middle of my farm and the farmer that was leasing my land asked if he could dig a long recycling pond ( we couldn't call it a dam or a lake - council regulations) so he could use more of the land. I said twist my arm knowing full well the potential of such a body of water. The surrounding areas drain into it and the whole area floods if we get more than 100mm of rain. The pond is definitely long enough, but was really only wide enough for winching (~15-20m wide) and it pretty much sat there for 10 years. He only pumped out of it once in that time.

The second image shows my plans and the estimated final tower positions - unfortunately it was dug too close to the existing track so I have to run the cable over it (system would fit but anchors would not). I thought long and hard about this but decided that if it was too much I can fill some of the lake in and move it forward down the track.

There's a long story behind the purchase of the park (I'll probably tell it sometime if anyone is interested) however after 11 years of working towards a house everything went ahead, and we were able to scrounge together enough to buy it. I immediately started draining the lake so it could be excavated. This poor little 6.5hp pump managed to drain the lake 1.5m (I ran it twice a day, sometimes more) over 4 months. I should mention at this stage, budget is very tight. I'm a teacher and sole income earner.
I also had to excavate some of the gutters on my property to help the water get away as the gutters weren't surveyed or leveled when put in.

Being an old cane farm and not really knowing who had worked it and what chemicals were used over that time, I decided to do a large set of water and soil testing for chemicals, metals, pesticides, herbicides - the works. Water quality is really important and although we'd swum in it previously, it had a lot of suspended clay making it look milky and I wanted to make sure. Over $400 worth of tests and everything came back with excellent results. The water quality is excellent. I will also be buying an electric pump to oxygenate the water (water fountain feature?)

Last one for today - after draining the lake I got it excavated. To save money, the last cut dumped dirt next to the lake. I'm still not sure about this - it did save big $$$, and will reduce wind but may get in the way a little. Time will tell, I've already cut 2 big holes in it on the natural water paths so I don't end up with a swamp either side of the walls. Thank goodness for 4 in 1 buckets on tractors.

I love air tricks. As the system is 6m tall and I have to go across a road, i thought I'd build some pads to put the towers on to give me a little extra height . They are currently 1.5m tall, but I'm guessing they will compact over time (yes, 20t excavator compacted them as much as it could but gravity and water will still make a difference). This also will keep the system high and dry as the whole area is covered in a couple inches of water after heavy rain.

From the same spot as the pump earlier.

Thanks for posting all this! I really want to keep hearing more about this whole process.
BTW I'm a teacher too and probably like many on here, have always dreamed of having my own park. So it's pretty cool to see you doing this. I can live my dream vicariously through you haha.

I always mess around with SketchUp designing my dream parks. Here's one that's kind of "realistic" but probably still out of your budget especially with the bi level pool. Just thought I'd share anyway. If you can make this set up, I will be even more envious than I already am!

That's amazing Andy! Maybe I should move the track and make that section the upper level ...Probably WAY in the future. There's some awesome obstacles there.

So onto the system itself - It's a Sesitec System 2 from 2014. The park was a great little park that we have many fond memories of however due to illness the owners were unable to run it as a business any more. It shut down in 2017 and had been sitting there for 3 years. It runs on a Generator (which I will hopefully be able to save enough to put on a 3 phase connection before it dies).
The Generator got some water in the sump so we've flushed it a few times with new oil, and will need a new muffler, other than that it is working fine.
The System itself looks a little weathered (hence me wanting sesitec to reply re parts/ servicing). I'm hoping to pull it apart a little this weekend and clean it up/re-grease everything.

As you can see, the kickers aren't in great condition and will need to be rebuilt.

I bought a 400m coil of rope. This is to work out center as well as ensure the anchors & towers line up, and finally is used to pull the cable through, Unfortunately about 3/4 of the way to the other end I dropped it. After a couple of hours of untangling I had enough to get to the other end and run it between the center marks. I have another 150m of tangled rope sitting in my car for another day

The next time I complain about my boat rope/handle getting tangled I'll try to remember this...

It's certainly put those tangles into perspective!

On to the anchors - they need to be 1.5 x 1.5 and 1.2m deep I lined them up using the rope and stakes at my center points, then made sure they were square. Who'd have thought Trigonometry would be important in building a cable park!

awesome. I've also drawn up many a park in various configs over the years. Even walked a few tracts and discussed numbers but something always came up. sub'd and looking forward to updates.

I look forward to hearing your ideas! At the moment it will be pretty boring until I can get more hands on deck to build obstacles - a couple of kickers straight up but hopefully a pipe and some wallrides, A frames and anything else we can put together.

The area I've chosen used to be a Melaleuca swamp (we call them paperbark trees in Aus) It was cleared a decade before we bought the property. More on that in a second...

We're in the middle of a drought which has been good for me to resize the lake, but has made the clay ultra hard to dig in accurately. Dug out the anchors - took me a whole day. One end was the super hard clay and was fiddly to say the least. The other end was the reason I mentioned the paperbark swamp, because I wondered what happened to all the logs. Turns out that they were buried and anytime I managed to get a wall accurate I'd snag a log and bring half of the wall down Nothing extra concrete can't fix I guess.
The steel and rio is being bent as you read this and hopefully the anchors will be poured next week.

digging that dry clay probably sucks, but good to know your anchors and water are staying put!

Absolutely! I was worried that in making it bigger I'd go too far, hit sandy loam and it'd all seep out but apparently there was no chance of that happening

Motor time. Had a mate (Jet engineer!) give up his weekend to help service the motor. I'm not the handiest of people but it was great how simple the set up is (to a degree). We pulled the grease points out and made sure they were working and re-greased everything that needed it, made a list of bolts that need replacing and put some lithium grease on the rest. We had a good look in the gear box but I still didn't know how much gear oil to put in at the time. Sesitec replied to some messages on Facebook (cheers!) so I think we've got the gear oil height sorted for now.

Despite looking very weathered, everything is in good condition!

We also had a look at the deflection tower. The bearings were working well but I noticed that the pulley wheel was worn. I had an unused spare that we rescued from the park - the shipping container that held all the spare parts had rusted through and water had been getting in for a couple of years so unfortunately a tremendous amount of gear was ruined. The spare pulley's bearings were corroded beyond recovery. We thought about swapping the bearings but we decided to get some new ones. Hopefully they'll be ready in the next couple of weeks.
