Abstract
A system for cutting marine grasses, weeds and other plant life to protect a propeller drive watercraft is disclosed. An adjustable, protective cutting edge to protect a propeller, drive shaft of a boat or other watercraft motor is further disclosed. A propeller protection device to mount upon a watercraft is further disclosed for optimizing the navigation of watercraft and reducing in-piloting maintenance of clearing plant matter from a propeller of a watercraft.
Claims18
A propeller protection device comprising:
- a base configured to affix to at least one of a motor housing and shaft of a watercraft, the base comprising a first base opening;
- and
- a cutting implement, the cutting implement capable of detachably mating to the base, the cutting implement having a cutting side proximal to propeller blades of the watercraft;
- the cutting side having a cutting surface on at least a portion of a side of the cutting implement;
- the cutting implement comprising a fixation element that may secure the cutting implement to the base so that the cutting surface may be set at a preferred distance from the propeller blades, the cutting implement further comprising a first implement mating channel, whereas the fixation element may be disposed therethrough the first base opening and the first implement mating channel thereby securing the base and cutting implement together.

A propeller protection system, the system comprising:
- a base configured to affix to at least one of a motor housing and shaft of a watercraft;
- and
- a cutting implement capable of mating with the base, the cutting implement comprising a cutting surface having an adjustable relationship to the base, the cutting surface being configured to adjustably move towards propeller blades of a watercraft, the cutting implement further comprising a cutting edge located on at least a portion of the cutting implement;
- the cutting implement comprising a trailing portion opposite that of the propeller blade side of the cutting implement, the cutting implement further comprising an implement mating channel extending between the cutting edge and the trailing portion of the cutting implement, the mating channel having an arcuate path configured to allow adjustment of the cutting implement's proximity to the propeller blades and disposition upon the base.
