Hi,
My Popeye has a Neu 1515 1y and have been running a bit hot, and that was January. I have 4s2p, Dinogy 5000mah batteries and a Seaking 180 ESC, running a De-T'd X447/3.
I have attributed the issue to the inadequate pick up of water from the TFL rudder . I made a propwash pick up to test/compare my theory and here is my puzzle:
When I initially ran the boat low speed to med.-low speed so that I can see if water is coming out , I was relieved to see a stream of water gushing out. This never happened when using the rudder pick up. Then I went full throttle and 2 min. 30 sec. later everything de-soldered and the motor had the distinct burnt smell. I have already sent the motor back to Neu for repair this afternoon.
First:
My original suspicion was correct, when the boat is moving at a med. speed, the propwash pick up afforded much better water flow.
Second,
The melt down could not be blamed totally on my set up alone because I have run this before though in much cooler temperature season. At that time the end bell of motor was 126* F, a Leopard 4074, 2000kv motor was also used and the temp was 110 or lower at that time.
IS it possible that at full speed the propwash pick up is not doing its job??
Here is the thread I asked the other day: http://forums.offshoreelectrics.com/...nd-give-advice

I have moved to the other side of the strut and it is more or less at 2 o'clock position as suggested by members here.
The TFL rudder looks like this:TFL rudder.jpg, it has small pick up on BOTH sides and the machining has taken the material in the middle away, I can elongate it but by the time I am done it is just a hole on the rudder
