What TP engine is this ?

[Jlov]

I recently purchased this boat with this motor in it and I can?t find any info on it can anyone tell me what TP Power motor this is and what KV it is or any information on it. Thank you in advance Jeff

What is the can diameter and length? The KV you will have to find my testing.

As Tyler mentioned, measure the motor and cross reference it to models available on the TP Power website. No way to know kV without testing RPM on a known voltage, assuming the hand written kV rating sticker has been removed. Those don't last long.

Can you not contact the previous owner?

If you can rotate the motor in the mount, you may find a label on the can near the back end bell. BTW, you might want to put zip ties on those cooling hoses.

[Jlov]

The motor is 4 1/2 in long and 7 1/4 in diameter. I was also thinking maybe the KV is on the motor underneath the cooling sleeve. I will zip tie all the hoses yes thanks

You might want to consider measuring again or checking out your measuring instrument. I seriously doubt that the motor is 7 1/4" in diameter. That would be the size of a gallon paint can.

I measured around the outside diameter. I guess the measurement required was 2 1/8 in diameter x 4 1/2 in long

[Jlov]

I took Zoomas advice and rotated the motor and hand written tag was still there. Thanks everyone

I think this is the motor the specs on the diameter and the length match up as well as the KV

Also when I got this boat the ESC was burned up. I ordered this one,will this be ample enough for this boat? Octura x648 prop. Im running 5S and 6S batteries in series

A little on the small side.
The motor is {Continuous Power (W): 7200}
On 6S this would be 300A

What size boat is this beast in?

Back to Amazon goes that 180amp ESC. Now on the hunt for a 300 amp like you suggested. There’s one in offshores store for $300. Will that one be ok ?

If your not going over 8S the Castle will take over 300 amps, Stump Fab has water cooling plates so surf the site a bit. On 8S 970kv would be a no load 28700 rpm and probably 21000-23000 actual. 67-72mm (gas props) might work as you have the power

As Mic proposes, get the castle XLX2 with the Stump Fab cooler.

[Jlov]

Thank you I will order it today

The Castle XLX2 has a max voltage of 8S.
I don't have any experience with cats this big, but isn't that a bit low of a voltage for something this big with a 970 KV?
Wouldn't it be more suitable to 10-12 S?

Larry,

The Castle 2028 has a 780kv and runs very nicely on 8S. 970kv is sweet spot for 8S assuming you have stout controller which is the case with the XLX2. The 5860 and 2028 are similar size motors.

The nice thing on 8S over 6S is lower amps and with all the P - 4S batteries we have already, S class works. 4 5000ma 4S packs series then parallel is 10000ma 8S that should power a large cat.
In some of my 2 lap testing on 8S the Castle XL2 pulling over 300 amps (7500 watts)never went over 120 degrees.

Guys I appreciate everyone’s advice and help they’ve given me since I started posting again with this new boat. But I think I have just come to realize I am in way too over my head with this type of bigger boat. My knowledge from years ago has left me and I just don’t feel comfortable putting this thing together and then running it. I went to my local hobby town here today and bought a ready to run blackjack 42 as I think this is more along the lines for me to get my feet wet getting back into this electric boating. Therefore I will be listing all this for sale in the swap shop soon including the new stand and travel bag I built for it and the brand new castle XLX2 that I ordered from stump fabrication today. Again thanks for all the help but I was in over my head with this boat and glad I realized it in advance before I flipped this thing or crashed it costing myself a fortune. Thanks again for all the advice.
