A propeller lock system to be used in combination with a boat motor which has a propeller shaft housing and a concentrically positioned spaced apart outer propeller housing with a plurality of lugs radially extending from said propeller shaft housing to said propeller housing, said lock system comprising;
- an inner fin lock adapted for positioning between said propeller shaft housing and said propeller housing, having a top cover portion and a lower lug gripping edge,
- an outer fin lock also adapted to position between said propeller shaft housing and said propeller housing, said outer fin lock having a top cover portion and an elongated body portion, said elongated body portion being of sufficient width to nearly completely fill the annular space between two of said lugs, and
- means to lock said inner and outer fin locks together whereby free rotation of said inner fin lock to a position where it can be removed without its inner gripping edge engaging one of said lugs, is prevented.
