Hello I recently got two of the new sonicwake v2 boats and while I do love the boat I absolutely do not love the average temp of the ESC in this boat. One boat already has had a warranty ESC replacement from horizon and it too runs spicy. We have a pond in our yard we run our boats in but it's not the biggest (I can run it full throttle about 3 seconds before I have to back off to turn back the other way) so they don't get a lot of time with high water flow through the electronics for cooling besides when we do make out trip to the lake and I'm thinking about mounting water pumps in them just just for the ESC because the motors average 90-100⁰ while the ESC is usually around 120⁰ in them I figured If I put a water pump in and keep a constant flow it's gotta help right ? I'm looking at one on Amazon that plugs into the ESC and pumps 600ml/min. I'm not 100% worried about the performance setback as I'm driving these with my 5 and 10 year old kids so just keeping them in good running order for them to have fun with us the top priority over speed

I dont know anything about the boats but you may simply upgrade to a better esc?
What brand (spektrum?)and amp rating is that esc?
It's the stock spectrum firma 120amp ESC. I will eventually upgrade it but even when I do if my pond isn't big enough to go fast enough to circulate water through the cooling system it's still going to have temp issues even with an upgraded ESC

Are those Celsius temps, or Fahrenheit? If F, those temps are perfectly fine. RC electronics are good up to about 200°+F typically, but a good rule to gollow is keep them below 160°F, just in case ya get added load which would spike the temps.

If those are Celsius values, then ya, you're running a bit hot.

This looks pretty cheap, and might work for ya if needed.

Yeah it's fahrenheit temps but that's after less then 5 minutes of run time just a pass or two in the pond and it's at 120 and from there if I don't pop the top and let it cool ittl go up 5-10⁰ per pass because the lack of water flow. That's the pump I'm looking at I was just curious if anyone had experience with those

Something with a little more capacity should in theory, not work as hard which would bring temps down. The hobbywing seaking 160A is $130 though so…. A small investment
120 degrees is aight though.

If your ESC went out at those temps, chances are it was just a bad ESC. Run the piss out of it and check the temps then. Adding a water pump may help, but you're also adding weight, which could counteract the effect of better water flow. And it will also shorten your run time 😉

No the last one was at 205⁰f when I popped the top and and it was temp locked but that was after a 4 minute run in the pond
 
I also know nothing about scale boating really. Assuming the cooling system is working properly, maybe running the boat on a smaller system will help.
If its 4s, try 3s...
It will slow the boat down and keep at rev longer before you have to slow down when yoy run in those short ponds.
Yoy gotta think, a boat is working REAL HARD to get on plane, then its smooth and easy once its up on top of the water.
Your boat is always fighting to get on plane, its never on top, always fighting.
I bet a smaller boat will woek better for your location.

To verify, bring your boat to a large lake and run it. Check temps and compare. 👍

I think you have too much boat for too little pond. 🤷‍♀️
 
Well took her out to the lake yesterday and made about 4 passes and got ready to bring it in to check temps and it stalled so I had to paddle out to get it and this is what happened. It was in the water for about 3 minutes before this happened.

The boat is great but I recommend buying the bare hull and stuffing your own electronics it will cost you more upfront but less down the road I feel. I don't understand how they sell the spectrum 120amp ESC as a 6s ESC if it can't handle 6s

Time to ditch the spektrum? What was the temp on the motor? Does the motor get the cooling tubes first then to the ESC? If so, can you swap them so ESC gets cooled first then motor?
 
Any marine water cooling pick up should create flow at any speed above dead slow. I would look into the pick-up and either extend it, or add another. The former should provide more than enough. Water pick-ups should also be in the flow of the prop so that they do not rely upon forward movement to cool.
