9. The propeller shield apparatus according to claim 1 , wherein said propeller shield has a first depth dimension equal to or greater than a second depth dimension of said exposed propeller, said first and second depth dimensions measured parallel to said horizontal axis in a vertical plane that contains said horizontal axis.

10. A propeller shield apparatus for mounting to a trolling motor having an exposed propeller with a horizontal axis, comprising:

a vertical fin;

an arcuate propeller shield oriented concave downward and fixed to said vertical fin; and

a curved bracket fixed to said vertical fin and configured to be clamped to said trolling motor;

wherein said vertical fin spaces said propeller shield above said propeller, wherein said vertical fin extends above said propeller shield.

11. The propeller shield apparatus for mounting to a trolling motor having an exposed propeller with a horizontal axis, comprising:

a vertical fin configured to be carried by said trolling motor;

an arcuate, substantially imperforate propeller shield oriented concave downward and fixed to said vertical fin, said vertical fin extending below said shield;

angular fins connected to opposite ends of said propeller shield, said angular fins oriented at about 90 degrees to a top surface of said propeller shield; and

wherein said vertical fin spaces said propeller shield above said propeller reducing air intake into said propeller when said trolling motor is operated in shallow water.

12. The propeller shield apparatus according to claim 11 wherein said propeller shield is substantially semi-cylindrical, having a radius of between about 5.5 to 7 inches.

13. The propeller shield apparatus according to claim 12 , wherein said angular fins are oriented substantially radially to the horizontal axis, said angular fins having a height extending above a top surface of said propeller shield of about 0.5 inches.
