Hi,
I have considered low power electric for quite a while to use for
docking etc.
a single 500w motor is almost certainly not enough, as said by those who
have actual practice in doing this stuff.
You might be better scouting around scrapyards for something bigger, or
as mentioned, going multiple, as I am.
As far as the method used, toothed belts seem to be the way. But it is
probably easier and really cheap to use vee belts for experimentation.
I am setting up with a simple steel plate that a flanged self-aligning
bearing bolts to. Although these industrial bearing are not set up for
thrust loads, they are used successfully by others for the small thrust
loads in a boat. They are also available in what I think from memory was
'food grade' which is basically more rust resistant so that machinery
can be hosed down.
You may have to enclose the motor(s) to meet coastguard regulations re
electrical sparks.
You will need slotted or swinging motor mounts, or a tensioner pulley,
to tension the belt.
Another item you might consider is a disc on the shaft that would divert
any water spray from the motor area, if the gland leaked. (Although if
it is leaking badly that is probably not the main issue!)
Also, it is probably a good idea to have a long range option on the
boat, and if the motor drive assembly is durable, then a generator can
be used, otherwise an outboard might be an easy way to achieve this.
Go for it.
The great thing is, by being careful, you can use the single motor that
you have, and then add more as required.

I'm new here, and would greatly appreciate any help anyone can give me.
I recently purchased a 27' Sailboat, that had the Inborad missing. Has
the shaft waiting for whatever. I have a 24 volt 500 watt Scooter Motor,
thats been sitting around for a couple of years, and was wondering if I
could hook this up to my shaft, and use it only for getting out of the
Marina, and returning into my slip. Not looking at performance. If this
is possible, could anyone tell me what I would require to make this
setup. Just looking for a basic simple way to turn the prop.
Thanks
