Well I wasn't expecting anywhere close to the current speed But was hoping to at least pull out at least 8 knots for 6 hours and was thinking about adding a small diesel gen set some solar panels and some tow able generators. I realize all that would also add to the weight witch adds to the load on the batteries. Anyway I am living in the Azores and fuel is a killer here and I just want to be able to take the boat out do some fishing and come back Or maybe Cruz from one island to another or stay out a day or two on the water. No big hurry for anything here really laid back. Well unless the wind picks up fast witch it does some times here
Thanks!

Date: Saturday, June 25, 2011, 10:37 PMHi Jeff,
Like James said, if you don't mind a max speed of about 5kts, then you might consider electric. Put another way, think of your boat repowering your boat with a 10hp outboard. You should get the same performance as that, just like John's conversion on You Tube.
Going faster will take a much more powerful electric drive. So it depends on how you use your boat today.
An easy question in "how much gas do you usually use in a single day on the water?" Just thinking about the batteries, if you use golf cart style batteries, the usable equivelent of a 1 gallon gas tank will weigh about 800 pounds and cost about $2000. Upgrading to AGM will drop the weight to about 750 pounds and cost about $4000. Going high tech, you could buy Lithium cells that only weigh 350 pounds and cost about $6200. All of that for a "gas tank" that drive your boat as far as 1 gallon of gas today.
If you usually use 5 gallons of gas in a day, then multiply the numbers listed above by 5 and you'll be in the ballpark.
If this sound OK, then we can start trying to figure out what kind of drive (electric motor) can deliver your desired level of performance.
Fair winds,
Eric

There would likely be little if any in weight savings, after adding the batteries. If on the other hand you want to travel at the boats normal 20 knots then unless you have a generator as large as the motor your removing, the batteries range would be counted in minutes not hours of travel time.

I have been seriously thinking of converting the Chevy 350 V8 to electric drive has anyone had any luck in converting a Dual prop out drive to electric any ideas on where I should start and what I should try. I figure with getting rid of the 100 gallon fuel tank and the big v8 engine I should be able to cut back allot on the current weight and give myself plenty of room for batteries. I would appreciate any ideas as i know nothing of electric motor conversion
