Oh boy, what a weekend. Had my hands into the boat most of the time. Turned out that I had two bad esc's, and took me sometime to figure that out, and while testing one of them started to burn! Could have turned ugly as I had bypassed the fuses while testing but I managed to pull the wires in time. I've had good experience from Mtronics esc's over the years and have used many of them in many boats without problems, but now I'm a little concerned.
As I had bought a replacement already I decided to go ahead. I pulled another one from one of my other boats. Problems again! Turned out that I had ordered the Marine 15 Plug & Play instead of the ordinary one. Don't know if it was due to this esc is autosetting or I was trigger happy but the bow thruster started with very high rpm and then stopped hard causing the shaft to bend and jamming the impeller. I'm happy that I made my homemade thruster removable even though, again, access is a pain in the ***! Well, electronics done and now I'll make a new impeller for the thruster. Then have to figure out if the esc problems where due to bad manufacturing or something else.
