  i think this would be far to small for a 36 shockwave, just going on the shaft size id say that its a smallish motor, get a kb45 8L for the shockwave and a turnigy 180amp boat esc, and a couple of flightpower 30c 2600mah 4s lipos to run parallel as 4s2p.. you should see 50mph with a decent driveline setup
     
-Reply from Madmax64 (1 points);
You will need a bigger motor 3660 model whit 2000kv to 3500kv rpm. Max

  What's the best speed you got from this motor installed in a mini hydro? Will it survive 4S?
     
-Reply from Eric1180 (2286 points);
common sense would say 4s with a 4800kv!!! motor would be to much. Thats almost 70,000rpm unloaded way to much. 3s is almost pushing it
-Reply from Dirk (13 points);
2s is best, if you got more kv, select the 3060 Kv

-Reply from Madmax64 (1 points);
Le mieux c'est un esc marin! donc avec un systeme de refroidisement a l'eau, il doit ètre résistant a l'eau(waterproof ou marine) , avec une puissance de 25a au minimum. Moi j'ai un 35a seaking . Max

In a 36 inch you'd probably want a lower kv with more torque.

No, it would not. Think about what you are asking for a second. a 20mm motor for a 36inch boat!?!?! you need a 40mm motor MINIMUM for a boat that size.

  I used a 26mm prop (slingshot by compass), 40A esc,11.1v 2700mah 30c 3 cell lipo(new)with about 30 min run time, a new 2200mah 3 cell 25c battery got hot and puffed up, in a striped Aquacraft Hammer abs plastic hull. It got about 27mph, It Jumped out of the water when full power given at start. My setup had Zero shaft vibration, On 10th run went to 24mm prop got better rpm, lost 2mph and then the magnet armature broke in half inside the motor and jammed up. Worst motor ever! I WANT MY MONEY BACK!

  Would this motor be a good replacement for the Delta Force 16". ??? The stock motor is a 2200kv with 3s 2200mh. Would the stock 45amp esc be enough for this motor???
     
-Reply from AM1508 (20 points);
guess not..its way to much kv's!! with the same prop these will suck more than 45Amps..so use a much smaller prop or reduce the kv..try between a 2800 or 3200 kv motor on 3s or use a 2s pack with these motor and a 28-30mm prop so you can use your 45A esc..greetz

  Can this motor be used to upgrade from a Brushed Graupner Speed 400 7,2V? i use 2 motors in my boat. what ESC would fit 2 of those motors? tks guys
     
-Reply from steamboatbob (5 points);
depends this is a very high revving motor on 7.4V it will be generating 35,000 rpm and it does get very hot when a small load is put on it
if you are replacing twin 400s i would actually go for the next size motor up as this will give you more tourque this motor is really meant for micro hulls.
-Reply from boatee (339 points);
To run two motors use two ESCs. I'd use 2 30/35 amp ESCs fed from the battery with a Y cable (available from Hobbyking) As for the voltage, the maximum it will take is rated at 11 volts so your 7.2 should be OK. Id be tempted to spend a little extra and get two Turnigy Marine 35A Brushless Boat ESCs. Well built and rugged. You certainly won't have any heat problems.

-Reply from Phill63 (138 points);
If it will fit in your boat mechanically then you can use them. Use a seperate ESC for each motor. You could run each ESC on a seperate channel in your Tx and then mix the channels to get a balanced power output, or run a "Y" lead from your Rx to each ESC.
-Reply from Adam (9 points);
i use a 25amp with mine although a bigger esc would be a better safe guard

usually the rudder on your boat has a water pickup and you can connect that to your motor using silicone tubing.

Turnigy 35 amp brushless boat esc

25 amps would do the job but with all my boats I overdo the ESC I'd go 40 amps to be safe. It's worth the few dollars to be sure. Make sure it's watercooled too.

turnigy marine 35a water cooled. i use with it.

If you ar going to push this motor to the limit , then 35 amp is not enough. 45 or 50 amp is needed for racing.

Have you test it out yet? I have the same set up for my mosquito craft but i havent test it out in the lake yet so idk if the esc will get hot. But i tested it for 5 mins full throttle without water cooling for the esc and it was still cool. But again that was without shaft or prop and outside of the water.

Nah man i i was you id go for something a bit bigger. like the size up from this 2848SL 3900kv Brushless Inrunner then it should be all sweet :)
-Reply from waterlogged (3746 points);
A hydroplane is a boat. DUH! You could put this in a boat, that's what it's built for but I think the 27 inch would be a bit much unless you use a small prop and run on 7.4 volts 2s. It's only a baby so it's really suited to much smaller boats like the Cobra.

  The motors max voltage is 11v but will running 14.8 burn it out straight away or will it just get hotter faster?
     
-Reply from GliderJack (6 points);
With 11,1V its getting hot very fast... You cant use it without watercooling with 11,1v, bescause it would get too hot. I think with 14,8V watercooling would not help. I'm sure that this little powerful motor will burn out... :-/

The size of the boat is about right. The ESC would do the job too. Prop should be around 31mm. Look around, HK has a number of smaller sized nylon props as well as metal ones.

This little motor really screams and would be a good motor for your boat. Just be careful fitting the cooling hoses. If you put too much pressure on the especially sideways they will snap. Try soaking your hose end in hot water before fitting. It will just slide on easily.

i need a brushless one and the prop size is 25 mm
-Reply from fastnut007 (18 points);
hi again ,still say kv`s of this motor too high on 3s for what you want ,something between 2500/3000kv`s would run cooler and longer on a 25mm prop calculation ,3sx4400 run time 30min`s equals max power draw =100 watts ,hope this helps,cheers.

your information was very helpful.

-Reply from Probelzaelo (2 points);
I think, use this one for submarine with 3S is not good idea. The best use this motor http://www.hobbyking.com/hobbyking/store/__4491__KDA_20_40_31Turn_L_Brushless_Inrunner.html with same size but small KV1800 And water cooling jacket like this http://www.hobbyking.com/hobbyking/store/__12688__Water_Cooling_for_20_size_motor.html so you have same watercolled boat motor but with small power consum.
-Reply from Morten (1 points);
Lower KV if you have to use 3S, but maybe if you use an 2S. Remember to get cooling to this engine, mine got burned after 1 -15 minutes with a failure in the cooling circuit.

  Hi could someone please tell me if this motor is compatible with a Turinigy Marine 35A Brushless Boat ESC and a Turinigy Nanotech 2200mah 3S 45 90c Lipo battery? The reason I ask is I'm running this set up in a Tearinto jet boat and only after 5 goes on the lake my engine has overheated an is seizing up.I have full flow of water running through the motor before the ESC... The first 3 goes on the lake everything was normal, on the fourth go the motor was warmer than the battery and on the fifth trial only got 3min before motor stopped.Have only had the boat up and running 2 weeks and never run twice in the same day..Any help would be much appreciated.

You could try getting the water cooled motor mount and also adding another water intake somehow. I fixed this motor on and old toy mastercraft boat from new bright. Im running it with a 50A birdy esc and 3s. Mine hasn't burnt yet.

-Reply from ShamrinHM (575 points);
If i may help, 29" boat will suited 28 or 36mm motor. These motor is way too small for your boat. These motor for me is for small boats (less than 500mm).BTW if i may ask, what will be your target? speed? 2S or 3S set up?

Above 40s, with these motor is hard to achieve that.
Take these 36mm motor PRODUCT ID: XK3674-B-2200
ESC you can use these PRODUCT ID: TR-M-120A
Prop, either PRODUCT ID: 377000016 or PRODUCT ID: 215000008 (currently available, others is backorder)
Lipos, single 4S or 2x2S in series rated above 30C
Im running my 31" mono with that motor on 4S, 45mm aloy prop (mentioned above) and reached 40mph with no problem. Hope this help.
-Reply from ShamrinHM (575 points);
Btw, you need to buy cooling jacket from eBay, search for 36mm long version cooling jacket or just buy these PRODUCT ID: 151000016.
Just make sure you drive system is 4mm or bigger. So it will last long due to more current/amp flow from all the electronics. Sorry, im talking too much here. Hope this help.

-Reply from ShamrinHM (575 points);
Sorry to hear that pal, anyway basic programming is using Tx/Controller..my steps as below:-
1- Connect your Motor to the Esc
2- Switch ON you Tx and put/push your trigger on FULL SPEED
3- Then Connect your Esc and Lipo together
-Reply from ShamrinHM (575 points);
Make sure your Trigger still at full speed after these 3 steps..
After that, you can hear programming tones..after 3 musical tones, there will be another tones (optional tones, 5/6 different tones)
If i were you i will only change the 1st setting, which is Movement (forward and reverse options),
-Reply from ShamrinHM (575 points);
Wait pal, there is still another steps, i need to type it step by step..to make it simple, try download manual from Turnigy Marine ESC on a File Tab, from there you will get what i mean.

-Reply from ShamrinHM (575 points);
Once you let go the trigger it will enter to the program options, this will be difficult..just change the 1st options only so that your esc can responded to all..
after the single tones let the trigger go and you will hear another tones, Then put ther trigger on Full Speed again after another single tones.
THEN SWITCH off the TX
-Reply from ShamrinHM (575 points);
Disconnect your lipo and esc, then
try Reconnect it again, it should be bound already..

-Reply from waterlogged (3746 points);
The ESC could be cutting out due to overheating. Try increasing the water intake by fitting a transom intake. I've seen a piece of copper tubing and even a piece of carbon fiber pipe cut a 45 degrees and epoxied to the transom to pick up water. Run the two intakes through a T piece and always go through the ESC first then into the motor then over the side. Make sure you wire tie the hose fittings to stop blow out from pressure.

Use a 2850 motor with a low kv. something like 3000kv with 2S battery.

For a scale police boat of that size, I 'd rather use this one: Turnigy D2836/11 750KV Brushless Outrunner Motor with 3S battery. If speed really isn't of any concern a 2S would do too. 3000kV is way too much for this project.

Hello, you can use two speed controls each 60A. OR you can use 120A or 150A ESCs Thanks. Best Regards

  Hello everybody, somebody could tell me if this speed controller ( HobbyKing 50A Boat ESC 3A UBEC) will be compatible with this motor?, with a lipo 3S,1200mah 28C? Thank you in advance Maxime

Yes but go with a 60 amp speedy at least. Its cheap insurance.

I'd Say it will run just fine with that ESC considering it's a very Current demanding motor. Though it goes pretty good at RPM, This motor is really a good deal for my planned boat.

  Hello... I am more into classic, wood model boats. I am soon to be building a model 1939 Chris-craft barrel back. I want her to cut through the water just like the real one and I also want her to have power and stability... Since this motor seems it would be nice, and it would look more realistic with it actually pumping water out the lower back like the real one. I am wondering if I should purchase this motor. Any suggestions are welcome! Thanks, Peter.

  I have a Apriton single motor running 2 3s 5000 mah lipos and a 150 amp ESC. Will this motor be able to handle what I have, Thanks Pete

Hello, Yes, but i dont think that this will give you enough power. BTW if ESC 60A will be good , means yes you can use the 150A easily. Best Regards

  Hi all, i want to put this in a 17'' proboat cat will it work? i dont know much about boats
     
-Reply from Mr wizzard (159 points);
this should work for you with a 28mm propdont try to go more the motor wont handel it.
-Reply from DaVilla (13 points);
I've used this on a 30mm 1.4P and didn't even get warm. Just make sure that you get good water cooling pressure. Run it fast enough so that enough water goes through the water pick up and cools the motor. If you run it slow or there is not enough waterflow then you are in danger of burning it out. I installed this on a Joysways Offshore Lite Deep Vee to replace the stock brushed motor. It was actually smaller than the original motor but used some epoxy putty to hold it in place and worked like a charm. Ran it on 2S 2200mAh 30C battery and you should have seen the speed.

  ESC: Could anyone recommend a suitable ESC for this motor from Hobbyking?
     
-Reply from MrBrick789 (71 points);
I used a 30amp hobbyking esc and it worked perfectly on 2s and 3a

  What size are the screws for this motor to mount?
     
-Reply from Ross (30 points);
2.5 mm. I find that if you lock tight a screw in then cut the head off you can make studs and have a nut hold the motor on. This makes for easy removing if need be. cheers.
