Djeeke, I've been working on this regen thing for quite a long time, sometimes making a little progress. I picked up a hydo generator at a pawn shop the other day that may add some good testing to my set up... This generator looks just like an outboard motor but has the possibility of putting a large prop on with out any modifications.. This means I can test on the back of my aluminum fishing boat with my 8hp and gps, get some good numbers and change props easy... I like it and wish I had another one, it would make a perfect electric outboard conversion... Dave K

Subject: [Electric Boats] convert outboard for generating power ... (and backup propulsion ?)
I have an unused outboard bracket on my transom...
(probably used by one of the former owners to hook up his dinghy outboard so he could use it as a backup engine)
In the thinking process of converting to electric I am also considering all possibilities of generating power... Solar, wind, and generators, including the trailing generators...
I have seen a few people converting an outboard to an electrical outboard, which seems to give some decent results and the setup does not look too difficult as a diy project...
Now, has anybody ever considered installing a generator in an outboard to generate more electricity? To me this seems a lot easier solution than towing a propellor behind my boat... I could easily have the 'outboard generator' sitting on that bracket and lower it in the water when I need a few more amps to recharge my batteries...
My next question would be what I could use ? Easiest might be a simple automotive alternator...
But while it's sitting there installed on the boat, it might be a good idea to be able to actually use the system as an emergency backup propulsion !
I know alternators can be used as motors but I have no clue about efficiency and maybe the stain of using it as a motor will destroy the bearings so it might be better to install another type of motor and use the regen capability...
What do you guys think ?
Djeeke
