Abstract
A system and apparatus for providing integrated boat thrusters which eliminates interfering with the integrity of the hull, and undesirable drilling and cutting of the hull to accommodate separate glass tubes or pipes that are conventionally used to form thruster tunnels. The instant system provides integrally molded thruster tunnel sections within the hull, and unique keystone inserts which are complementary to the molded thruster tunnel sections and complete the water flow chambers through the hull about the propellers. Separate tubes are not utilized. Thruster motors and mounting mechanisms are securely fastened in flat planes enhancing strength, performance and maintenance of the assemblies. In a preferred embodiment, the keystone insert is generally wedge shaped to provide a secure fit and bond within the molded tunnel section having angled walls.
