but be nice to me on the forum, I am not suggesting that anyone else do this. This is what I'm doing. I've already ripped out my old tired A4 and sold it for $100.00 just to be rid of it.
I'm using very easy components and over all it should be cheaper than a new deisel or gas install. I am putting an E-tex motor or similar on the exsisting shaft and putting in 8 x 6vdc to make a 48vdc battery bank. The over all weight of batteries, motor, controller should only be about 550-600 lbs... advantage is that it's closer to mid ship. The 410lbs of weight for engine and fuel
(fuel tank in tansom) which it is now replacing is closer to mid ship. I can rebuild
my engine coompartment for better stowage and the transom locker is now clear of Gas tank and I can put life jackets and bulky light stuff back there.
ratio component and the electric controller will let me regan electric current
while under sail, and tidal flows. I should be able to sail for a 4 hours and recharge the battery bank from the 30 minutes of motoring I did to get out of a harbor. The prop will be switched to a fixed 3 blade
at a higher pitch
a 12x12, instaed of that little 12x8 that basically just churns water
. An electric will turn a larger pitch
I plan on buying
a wind generator
from KISS that outputs a standard AC current
up to 1000 watts and convert that to 48vdc close to the bank for better charging
. Then I will use a step down converter from 48 to 12 for house equipment
Currently the price structure is as follows:
Etek style motor will be 500 to 800
Charge controller with regan is 200 to 400ish
Battery Bank is going to run me 600 to 900 depending on shipping
and distributor. I would have to have a battery bank anyway and a standard 12 volt would be about 150.
Wind Generator which I would buy regardless is about 1400 with everything.
So I'm looking at about 2.8-4k total price tag with the additional wind generator.
Now the good news if the motor goes down I can just replace it, if the batteries die after 10 years dito. Controllers are pretty cheap... everything but the batteries can be packed up and sent ups for repair or trade
in. Also for cruising I can carry a spare controller and motor for around 1200.00 similar to this package.

I'm actually using a different system and mine will be a little more expensive. But I like the component aspect of it.
I can also ad a gas or diesel genset... if I want to put it in a another boat I can easily do that myself I can lift
everything individually. Heaviest thing is a battery at 56lbs.
For me it's like a really big science project
... however if I had a new sailboat and was a weekend warrior and/or still worked a grewling career I don't know if I would have time to mess with it or the desire.
If you are a tinker-er and an DIY then electic conversion may be for you... if you are not then it isn't.
I'm also really frugal about certain things and in 3 years would have spent more on gas than on a battery bank, at 3.00 a gallon this summer it doesn't take long. 100 gallons of fuel a year at 3.00 a gallon is 600 bucks in three years. My battery bank should last about 5 to 10 years. In two years what will the gas price be during the summer? On a personal level do you want to own or rent your power?
But the best part is I can always install a kick plate to the transom and use a 15hp long shaft gasser in an emergency
/ the hillbilly hybrid
. So I'm never without options.
Again I can't stress this enough this is not for everyone and I don't suggest it for others. Also I moore my boat in Provincetown Harbor and lots of poeple here can sail in and off their moorings. So expeirementing with electric propulsion
is a little less frieghtening than being in a 3 mile congested channel.
