I have had some electric drive time under me, not on a boat
but hard use and not much care, I've run GE Elec-Traks for years, these were build in the late '60s to early '80s, How many of you have 40 year old lawn tractors still running? these things can be run hard for years then be left in a field for years, put in new batteries and off it goes agian, the motors are amazing, there is more than one moving part in most, you have bearings too, and brushes
wear. The big limiting thing with electric drive is the batteries. A hybrid system with LiFePO4
batteries sounds like a good package.
I'm thinking of trying to put together one, a 3GM30F and a pair of 2.5 hp GE shunt motors, I just want something that will run electric for 15-30 minutes, just to get out of the harbor or up to a dock
, no need to start the diesel
, let it warm up, run it for a few minutes, let it cool down, then shut it down, the diesel
is still there for long runs
