Latest Patents

One of his latest inventions is the outboard motor retainer. This innovative retainer is designed for transom-mounted outboard boat motors and is mounted on the inside face of the transom. It surrounds the area where the clamping thumb screws of the motor mounting bracket engage the transom. The retainer features a retaining lip that defines an undercut groove, which engages the pads on the clamping thumb screws. This design prevents the motor from shifting inadvertently out of position, thereby avoiding horizontal sliding or vertical tilting that could result in loss of the motor. The retainer is easy to attach to the boat transom and does not interfere with the attachment or removal of the motor.

Another notable patent is the bilge water pump mechanism for outboard motor cowl. This pump mechanism is continuously operable by the engine of an outboard motor and is designed to discharge water that collects due to seepage or leakage into the engine cowl. The mechanism includes an inlet conduit with an inlet end positioned closely adjacent to the bottom of an inclined channel formed in the lower section of the engine cowl. An outlet conduit has an outlet end positioned exteriorly of the cowl. A filter in the inlet conduit removes debris from the water, protecting the pump mechanism, while a bracket mounted to the engine block holds the inlet end of the inlet conduit in place.
