PWM controller

[GreyNurse]

Hi raiders,

I've decided that the two speed switch on my 18 lb thrust Watersnake, while being OK for getting to and coming back from fishing locations has been good enough, it does not allow for a good trolling speed. I want to fit a PWM controller to the motor. That part is easy, but can anyone recommend any particular controller? I take it that I would need at least one rated at 20 amps for my particular motor, as the fuse sold for these is rated at 50 amps.

Would I be better off paying $10 + for something sourced locally, or can I trust a sub $10 unit bought on line?

Hi Nursie. There's a YouTube video about this. He's an aussie guy with the same motor as you. He's really smart and helpful. I'll PM his details.

Thanks Ambrose. Actually, I made a small error. It's a 24lb thrust motor. Still draws 20 amps (the 18 draws 15 amps), so Nothing has changed as far as what I need.
