It would have to be leakage through the grounding system, yes? I wonder if there is any way to isolate the motor controls more effectively. > > Vance Hi BVance seems that some of them have the same problems..: http://www.xumba.scholleco.com/viewtopic.php?t=35&highlight=trolling+motor http://www.humminbird.com/support/FAQ.aspx?faqid=52 I have the sonar trouble with the MK-PM-Controller but not with the simple Rino Step controller. And also not if the MK-PM Controller ist switch to 100% power. I think it is the high frequenzy noise from the controller. And we have the same problem with the Euronauts big 40 KW PM-Motorcotroller and the same sonar even if the sonar is not attacht to the boat and some few meters away. My Electronic engineer think that he can later on the final installion fix that with meassuring all and than some extra filters. Seems on Peppers it is the only way to change the Mainmotor and Motorcontroller. No problems on the same boat with the step-controlled thrusters. And for this reason the KSS gets only step controlled motors. I like to have a sub can see 300 feet left and right and forward.. http://www.postimage.org/image.php?v=gx2jl1e9 vbr Carsten > > -----Original Message----- > From: MerlinSub@t-online.de > To: personal_submersibles@psubs.org > Sent: Sat, Jun 13, 2009 6:39 am > Subject: Re: [PSUBS-MAILIST] Side Thruster Options > > > > > Please note: The PM controller of minnkota do no work with any sonar. > You get only a huge amount of snow on your screen.. > > And a sub without sonar is nearly blind. > > VBR carsten > > "ronleonard@shaw.ca" <ronleonard@shaw.ca> schrieb: > > A couple of notes: > > The only difference between saltwater Minn Kotas and the standard Minn Kotas > > is the addition of a zinc prop nut to the saltwater motors.
