From my experience, you do need to consider the amount of wind and current when using a "trolling motor" and its smaller (4 inch) pitch.
EXAMPLE 1: O'Day 19 - 19', 1600 lbs, Endura 50 ($200), two GC2 batteries
This motor worked well for maneuvering in protected waters. I would go about 3 knots at best. If the tide/current was greater, I would move backwards.
EXAMPLE 2: Capri 22 - 22', 2250 lbs, Endura 50 ($200), two GC2 batteries
As with the first example, it worked acceptably for sheltered waters with the same velocity restrictions. This boat was much more susceptible to the effects of the wind. I could not get the motor to more the boat around fast enough in 10 knot winds.
EXAMPLE 3: Capri 22 - 22', 2250 lbs, Torqeedo Cruise 2 - 2011 tiller version ($2500), four GC2 batteries
Wonderfully responsive for maneuvering, much better than the Nissan 5 HP outboard we primarily used last year. I reached 5.5 knots over the ground against the incoming tide. Throttling back it would maintain almost that velocity.

If you were to use a trolling motor, you need to get one of the 24 or 36 volt versions to give you more propeller speed than the Endura 50 has. It is possible that the Torqeedo Travel models might meet your needs at just a little more cost than the larger trolling motors - AND it has the battery built in/attached!
Your local current/tide/wind conditions will dictate whether you can use the husky trolling motor and save a few dollars.

There is an inboard engine well and I would like to put an affordable electric outboard in the well. Torqeedo and other 'traditional' electric outboards seem too expensive, too powerful and too luxurious for my needs. All I want to do is get off the mooring in a narrow creek, motor to the bay 10 minutes away and then hoist sail and be gone. I think I could use a husky trolling motor with electric cable to a lead acid motorcycle battery in the cabin six feet forward. Weekdays I would put a solar panel on the small cabin top to recharge the motorcycle battery, or take the battery ashore for charging. The trolling motor would be easy to remove and store in the small cabin.
