Diagnosis: motor murder

[tlandauer]

Regardless which way the tubes are routed, and it looks to me too that the exit hose is on the collet/shaft end of the motor, hence it is lower than the entry point. We are talking about which nipples on the jacket in relationship to either the bow or stern of the boat---bow being the higher nipple and stern being the lower one. That is how the motor sits in the hull! Not how the jacket is "rotated" on the motor can! I personally don't believe that has anything to do with the death of the motor. Something else is the culprit.
I have almost the exact set up on my Pursuit, with a 4082 sized Leopard, temp was never an issue. In order for the plugs to desolder like that, one can imagine how high the temp was on the plugs. If the tin can roll down the wires all the way into the motor, it was like the tip of the solder iron was kept on those plugs for the entire run.

The front port side of nipple is high at the port side jacket and mount,
And that line is going out to exit port side of hull.

Exactly.... The lower nipple is connected from the esc, and the high nipple is exiting out the port side like you're saying. Not sure what you're trying to say but it looks right to me. The exit nipple is not as high as it possibly could be, but he's got it right.

He's got the water lines right Lenny. Look a little closer.

What were the temps of the setup before the melt down ?
Also what was the temp of the pond water before the melt down and how hot was it there today ?
I do see the that the water lines on the water jacket are backwards,
Water should come in at the lowest point and out at the highest point on the jacket.

4-6 minutes.

Gotta say the Pursuit has been a bad luck boat for me. I tried to get it out in the water last year. First time out I lost the flex/prop. Second time out couldnt keep her on the water, flipped over and ripped all the CA glued down stuff out (ESC mount, batt mount) and a little water got it ruining the batts.

How much time on the motor altogether?

[Basstronics]

32" Pursuit
Leopard 4074 2200kv 2Y
T180 ESC- STOCK no cooling mod
CNC 45mm X 1.4 pitch
Timing 11.25 Degrees
4s2p 5000mah 60C China Hobby line batts
8mm on batts, 5.5mm on motor


ALL but one 5.5 bullets on the motor desoldered. The wires leading down to the motor tinned with the solder rolling down them. Melted the plastic going into motor... Took me over 15 minutes to get boat back to shore due to my poor casting abilities...

Ran about 3 mins. Water was coming out of the outlet.

I used 60/40 clear rosin solder. The solder jobs looked beautiful too- so no cold joints.
