Thank you Jeremy, the Minnkota has a permanent magnet motor, the 40lb thrust model uses resistive speed controllers as standard and PWM for the next model up. The operating voltage is 12v and the maximum current is 35amps. approx. I had a look at the site you suggested and will email him to see if he can help, thanks again, regards, Arthur.

> One very reputable eBay seller is Keywin Ge, who trades via this eBay store: http://stores.

> I've purchased several controllers from him for different applications (I'm in the UK, so they've been long distance orders)and he's been very helpful. If he doesn't list something you're after, he'll happily just send a PayPal invoice direct if you email him.

> Off the top of my head I'm not sure what the voltage/current rating of the Minkota is, but the chances are that one like the $24, 36V, 40 amp unit, with the low voltage cut-off reduced (a fairly simple internal mod that Keywin may do for you if you ask) might do the job.
