I finally decided that I want to fish at Lakes where they do not allow jet skis, ski boats, outboard motors, or noisy people of any sort. So my 1969 Evinrude is going the way of the Dodo. I've got a couple of 55 pound thrust electric motors, and coupled with my 40 pound thrust Minn Kota, I should be able to navigate the calm Waters that I intend to fish. My neighbor Dave gave me these Navigator trolling motors, plus their brackets, controllers and wiring, 15 years ago. I am finally going to use them. Here's my first mock-up... The brackets will have to change completely and the original controllers are wasteful of electricity and I'm just going to wire these motors up with direct switching. Unfortunately electric motor controller circuits (even the modern ones) get very expensive when you're trying to control motors this large. Fortunately, since these work, I can sell them for a good amount of money on eBay since you cannot buy them anymore. I can use my 40 pound thrust motor for fine speed control and front steering, and the rear Motors will be on or off & tied by a rudder to my remote steering stick. So my next task is: I have to build a rudder. Then I will need some more batteries. Big ones. The boat will not get lighter, just quieter and more stable, since the weight will be distributed along the hull instead of mostly at the stern. Also I will probably eventually switch the rear Motors with simple switches from 6 to 12 to 24 volts, so I can at least have some speed control on them. On the other hand, after my first fishing trip I may decide this is completely unnecessary.
