Proboat Stealthwake 23 brushless conversion

If I don't have an incident with this one, I might actually be disappointed!

Now that cracked me up.
But I know exactly what you mean.

If you don't have an accident then your not driving hard enough.

I took it as well as I gave it out! What a great time. Just walked in the door. I need to get the snow blower prepped for a storm on the way and will post pics and videos tomorrow.

Yeah you're sure welcome anytime.

We have snow coming too, shouldn't be more than a few inches. I'll give the kids breakfast before I hand em a shovel.......LOL

Thank you for sharing your conversion to brushless on your Pro Boat Stealthwake. My son received one for Christmas 2018 and this summer we already burned up 2 brushed motors. I joined this forum to get tips on how to go brushless without going crazy. I love this boat and how it handles rough water and just want to get it to run a little faster, but mostly, just want to keep from burning up motors! We run our boats pretty much every weekend a few times between May and Oct.
I also have to say, the races at the indoor pool look spectacular! I wish we had one in northern IL.

We got the Pro Boat Stealthwake running well now with a brushless setup. Our goal was go get it running with only changes to the ESC and motor. We found a working combination with a Turnigy 90 amp marine ESC and a 3660 2600KV brushless motor. Everything else on the boat is stock at this point. With a 2S LiPo, it runs about 15 minutes without the motor and ESC getting more than slightly warm. We used a GPS speedometer to clock it at 25mph, which is almost 10mph faster than the brushed motor stock setup. The next upgrade will be a metal rudder since the stock plastic one is pretty "sloppy" and no amount of work I did to it helped much. But it works well enough for now.
Here's the video of the final upgrade: https://youtu.be/YzZffRRFp10 (I updated the video and this link after I originally posted here).

I'm looking to upgrade my Stealthwake to a brushless motor (just burned up the stock motor after running for 15 min on 2s lipo) and just found this forum. Great job on this! I'm kind of a newbie, so I'll spell out what I want to do and let you all give me pros and cons.

I want to replace the motor and esc, but not ready to tackle anything with the driveshaft yet. It looks like this upgrade achieved great results with a 2s battery and a 2600kv motor, so that's rpm of around 19,000 (2600 x 3.7 x 2). Since I know that gives good results without changing the prop, that's what I'm kind of using as my benchmark.

I'd like to go with a motor that has a built in water cooled sleeve, rather than use the stock water cooling winding around the motor. Only problem is, I can't find one that's 2600kv. I did find a Turingy 1700kv model (here: https://hobbyking.com/en_us/turnigy-...en_us_products). I can achieve close to the same rpm with this by stepping up to a 3s battery.

So, is my logic right here? Would a 2600kv motor w/ 2s power and a 1700kv motor with 3s power achieve roughly the same performance with the same prop? Or am I missing something? I don't want to overpower the boat and make it uncontrollable.

You can get a Leopard 3650 motor in 2290 or 2750 kv with a water jacket and 1/8" shaft here from OSE. Pair that with the OSE Raider esc for an economic upgrade. You are correct about running 3s. There are a couple of kv options for that as well.

Ok, so I took your advice and went with the Leopard 3650 2750kv paired with the OSE Raider esc. It was attractive because the Raider esc and the Lepoard motor both come with the 6mm bullet connectors so they go right together. I knew the esc was overkill for this setup, but that's fine, I can use it on another build at some point if I want to.

However, I overlooked the esc to battery connection. Since the esc is rated for 150 amps, it comes with some heavy duty connectors on the battery side. They're OSE-qs6p, which I think is just a 6mm bullet male/female bullet pair. All of my batteries are the yellow XT60 double female connectors. I also have some XT60 to EC3 adapters, so I need to get the OSE connector to either an XT60 or EC3. Can anyone suggest a good way to mate these two?

I could change the connector on the battery, but then I'd have to change my charger as well, since it has XT60 and EC3 connectors. I'd like to find an adapter, although not sure if one exists.

Why not just make up an adaptor XT60 to OSE?

I'm a newbie at this stuff....I'll need some more explanation to be able to do that.

Was hoping maybe there was an off the shelf adapter.

Question - is the OSE 6mm connector basically the same as an XT150?
