I was given an old hydro marine bud hydroplane that has a Hacker B50 10XL motor and a Jeti master navy 77 -3P esc. Boat has no batteries with it so don't know what it was running on. Any info about the esc would be great.

This may help.

Thanks, I saw that too but the one I'm looking for wasn't listed.
That motor in that hull usually runs on 4S1P.

You mean 4S lipo? That would be great as I have them. But I am unable to find out the specs for the speed control if it can handle them. JETI Master Navy 77-3P. It's the 3P that is screwing me up.
I never knew what the 3P meant or worried about it when I ran those.
If it does not say OPTO on it then it has a BEC circuit.
You can use NiMH or Lipo on these. If using NiMH you can use 12 cells, not sure of max Voltage though??

It does say Opto on it and 8-30 nc
3P means 3 Phase. A brushless motor, is in fact, a 3-phase motor. It was rated at 77 amps. Since it was designed for NiCds, there probably isn't a low-voltage cutoff. Capable of 36V or about 8S. 10S might work, but beware.....

Thanks, that is what I was trying to find out. Looks like I'll be buying a new speed control
