For a small fishing boat

I need info on a propulsion system based on a hand powered propeller / outboard drive system.

No gas motor, just human power.

Seems there used to be something that was similar to an out board that had nothing but perhaps a few bevel gears and a lever that functioned as a tiller that was jacked up and down for the power to spin the prop.

Any body remember any details?

thanks !

An uleau is an oar with about a 15 degree bend in the handle
perdendicular to the plane of the oar and a pivot at that point,
which presents the oar blade sideways, perpendicular to the desired
direction of travel. The end of the handle is tied by a piece of
rope several feet long to the interior of the boat. Moving the oar
handle sideways by pulling and pushing on the rope causes the blade,
along with the bend and pivot, to work in the water like the blade
of a propellor, equally to either side, "sculling" the oar. Each
reversal of the handle causes the blade to pivot a few degrees, so
the blade pushes or pulls the boat with each side to side motion.
Manipulation of the handle permits steering. The blade is lifted
from the water to enable coasting between strokes, if desirable.
Pushing or pulling harder to one side or the other also enables
steering.

A rubber flipper stuck on a typical rudder may also serve, with
technique.

I've seen a lot of human powered stuff just recently in my search for
info on building my own paddleboat. You can get some ideas here;

http://www.waterbiking.org/
http://www.humanpoweredboats.com

The paddle ideas seems the cheapest, simplest and surest way of
implementing human power, all it takes if you want to do it on the
cheap is an old bycicle, maybe one or two extra chains, a couple of
different size sprockets for experimenting and something to make the
paddle out of (can be wood), if you wanted to get fancy you could try
using the gears off a ten speed.
