I live on my boat and travel around so I need power,if all your going to do is out to raft up don't bother with the time and expense.
If you want to put a outboard on it that all you'll need for that little run.Get a high thrust if you can.
If your set on electric I'll send you a picture of a V drive set-up I
have.It's a 10hp motor collared to the V drive.Do 8 12 volt batteries 2 chargers and you 6.5 gen to run the chargers.(4 batteries 1 charger for each motor,48 volts)

If you choose twin 4kW motors, simple drive systems (motor and controller) cost about about $2000 a piece and then you need batteries. You suggested T-105s, a good inexpensive solution. Eight t-105's (48V) weigh about 500 pounds and cost about $1200. I would suggest a seperate bank for each motor.

If the motors were run at 60A (3kW), each battery bank has a usable range (65% depth of discharge) of just under 90 minutes. If your cruise speed with both motors ends up at 4kts, that is a range of just under 6 miles before you need a full recharge. Two 48V chargers will run another $1000, putting your basic installation past $7000.

Again, I do not plan on going far or running the motors long, I just want to get out to raft up by the beach, maybe 10 miles tops each way.... I know this will be slow but I want it to be safe and reliable. I am trying to do this for $3-5k if possible. I am also considering a 15hp outboard kicker as a backup.

With the original power this boat would do a very frightening 30+kts I just want something that will move this boat at 3-5kts. What sort of electric motors would I need to accomplish this? Could the motors be hooked to the v-drives or directly to the prop-shaft? Is this even a do-able project? I don't want to spend a fortune for this either. I have seen golf cart motors up to 24hp. Would something like that work in this case?
