Houseboats - Pontoon Boats - Workboat - Barges
PROPCO has patented a Reverse Hook Cup propeller for houseboats, which gives up to 200% more
 reversibility - something houseboat owners have been very excited about. This patented technology
 enables houseboat owners to turn more effectively, stop forward momentum and control their boat while in reverse.
Customers tell us that the new propeller "literally takes the fear out of returning to the marina,"
 and with this prop "the stern now will swing around and hold into the wind."
