An improved boat and drive assembly intended for a boat used in a primary shallow water environment has a hull with an integrated closed internal engine heat exchanger and a drive assembly that includes a ring-within-a-ring steering mechanism and an obstacle resistant shoe plate. Stabilizer fins positioned above the shoe plate at a position forward of the spinning propeller allow air and water to exit from the rear of the stabilizer fins away from the spinning propeller. The heat exchanger assembly may include an axillary cooling tank and open heat dissipation system having a raw water reservoir continuously filled with raw water drawn directly from the waterway on which the boat is propelled to enhance the cooling capacity of the integrated internal engine heat exchanger.

A trolling motor is provided comprising a motor housing, a motor controller, and a down tube assembly extending from the motor housing. When the trolling motor is in operation on a boat, the down tube assembly will support the motor housing submerged in water. The motor controller is mounted to the down tube assembly.

Provided is an outboard motor raising and lowering apparatus that is capable of automatically changing the speed of raising/lowering an outboard motor according to a status of the outboard motor. The outboard motor raising and lowering apparatus (1) includes: a first fluid passage that connects a pump (42), a second chamber(s) of one or more tilt cylinders (14), and a second chamber(s) of one or more trim cylinders (12); a second fluid passage that is connected to the first chamber of at least one of the one or more trim cylinders; and a switching valve (60) provided at the second fluid passage.

There is provided a mounting assembly for a marine vessel having a pair of stern-mounted propulsion units. The assembly includes a pair of angle-setting members which forwardly angle the propulsion units towards a bow of the marine vessel when each propulsion unit is at the center of its total steering range. Each propulsion unit has a line of action of its propulsion force. The lines of action of the propulsion units intersect each other between a center of rotation of the marine vessel and a stern of the marine vessel when the propulsion units are steered forwardly towards each other.

The present disclosure relates to a houseboat assembly formed from a cabin assembly secured to a hull assembly. In some version of the houseboat assembly, one or both of the cabin assembly and the hull assembly may be formed in accordance with a boat type and/or a floor plan. The boat type and/or floor plan may be selected by a customer. The cabin assembly may be formed at a first location and the hull assembly may be formed at a second location. The cabin assembly and hull assembly may then be transported to a third location. At the third location, the cabin assembly may be secured to the hull assembly to form the cabin assembly at the third location. The third location may be requested or specified by the customer.
