Spanky, I'd love to ask you some questions about your set up as I just got my Seaking 180 and leo 4082 from OSE. I'm not much of a builder at this point and I'm already confused. It seems to me from just placing the ESC in the boat that you wouldn't need to do any cutting? Also how did you install the 40mm mount? It looks to me like it only fits on the front of the motor near the shaft but it clearly to mea at least seems like it should be on the back of the motor to support the weight? Also as for the BEC of the ESC I have heard if you want to run 6S you need to disable it and use a separate RX battery. This is discouraging I was hoping not to have to go this route.
My Impulse 31 v2 upgrades with photos, it's comming along.

Hi jworm49, if I remember correctly it was a very very snug fit on my esc to get it in without some cutting, add in the additional height of the Velcro pad and it would not work for me so I trimmed the rails for easier installation. For the rear motor mount I installed it first from the front end of the motor and then slid it to the rear, then installed the water jacket. Even with the motor mount fully tightened down it was still a bit loose so I ran 1 layer of electrical tape around the inside of the mount and trimmed it to width and now when tightened down it is a nice and snug fit. As for the BEC, I guess it's always a good idea but I have not planned on using one in my boat, I will see what the BEC in the Seaking is like first. I see you went with the 4082 for your boat, that thing should really get the boat moving. Im running the 4074 and figure that alone will be a handful. From what I understand fast electric boats should be ran wide open for the most part ( slowing down for turns of course) so as to put less strain on the ESC and keep the temps down. If that's the case then you have a real screamer on your hands. What KV motor are you running with.Comment

I just placed the ESC in the boat loose but I did it opposite of you with the water nipples facing the front and rear of the boat it seems to fit ok. I'm waiting for a water jacket fro OSE before I can really start mounting anything. I'd be interested to see how you did the mounting feet for the 40mm ring as I'm not at all sure how I will go about it. I was planning on getting the 4074 as you did but it was out of stock so Steve recommend the kit I got with the 4082 I'm hopping it's not to much for the boat. It's a 1600KV.Comment

I've got everything soldered up now and will get started on the rear mounting brackets soon, I will post some photos when its done. Im going to have to wait until spring to run it as all the water is quite frozen up here now, I also have about 6 inches of snow on my field already. My guess is you will be up and running long before im able to. Im looking forward to some pics and a video of yours running when your able as well. The best I can do right now is possibly some snow boating with the Black Jack 29,we'll see how it goes for that though.I just placed the ESC in the boat loose but I did it opposite of you with the water nipples facing the front and rear of the boat it seems to fit ok.

Some pics of my built I still need to fine tun a few things but I ran it today on 4S and it went very well about the same speed as stock on 4S the boat with to 3S packs weighs in at 7lbs.CameraZOOM-20131116192533939.jpgCameraZOOM-20131116192614457.jpgComment

some video of my first runs still trying to find the right set up you can see in the second vid the right at the end the flex shaft snaps.

Wow it was running really good until the flex cable broke. Did it actually break or just come loose, I hope you didn't loose the shaft and prop. I purchased the OSE upgraded cable for mine and the Octura flex hex coupler. The coupler is easier on the cable and makes removal for greasing much easier. Your lucky, I see you had Tee shirt weather with your open water, up here its parka's and ice everywhere lol.Comment

Yeah it was about 60 that day and 40 the next but Yes the cable snapped right in half But stayed in the boat thankfully. I have the upgraded shaft fro OSE on the way as they are out of the HD ones, I'm also using a coupler a lil different from yours it has two set screw on the shaft. I was running an X440 to me it seemed a bit too small the front of the boat was pushing a bit. What prop are you running?Comment

The M series props are de-tongued. Are your props sharpened and balanced, if not you should look into that. What do you use for your recovery system, real boat, rc boat, wind or swim.Comment

I theory, this could be true, but in reality, the water is being forced in at a MUCH higher rate and pressure than it can escape... the water jacket will have so much water pressure in it that air won't be able to be trapped inside it, in my opinion. If the water is squirting out of the side of the boat several inches or more, I don't think you have anything to worry about. Water is going to be forced into the jacket and take up every bit of available space, purging it of air pretty quickly. Going to have to have some clear evidence to the contrary to convince me otherwise.
I'll experiment with that with my latest build-up and see...
As for the upgrades, looks like fun. Do yourself a favor... buy a set of these... Trust me! :)
