A marine steering system operable in either power steering or manual hydraulic modes. The system employs a modified helm pump having a single rotatable input shaft connectable to a steering wheel and dual hydraulic and electronic output. An encoder, such as an optical incremental encoder or hall effect device, is mechanically coupled to the input shaft for generating an electronic steering control signal representative of the change in position of the steering wheel. In the power steering mode, the electronic steering signal is processed by an amplifier controlling the operation of an auxiliary pumpset connected to the rudder steering cylinder. A bypass manifold disposed between the helm pump and the steering cylinder disables the hydraulic steering system in the power steering mode. In the event of power failure, the bypass manifold valves are opened and the system automatically switches to manual hydraulic steering.

A folding pontoon boat as in claim 1 wherein, in the folded configuration, said pontoons are spaced about 1 inch from each other. 7. A folding pontoon boat as in claim 3, said hinge connecting said inner sides of said first and second deck members to each other at the respective bottom edges of said inner sides and wherein, in the folded configuration, said pontoons are spaced no more than about 3 inches from each other. 8. A folding pontoon boat as in claim 1 wherein said first and second pontoons fold with said deck members thereby to bring lower portions of said first and second pontoons into facing relationship with each other. 9. A folding pontoon boat as in claim 1 and including a retraction device having first and second ends, said first end being mounted to one of said first pontoon or said first deck member, said second end being mounted to one of said second pontoon or said second deck member, said retraction device having a line of retractive action passing below said hinge, whereby a line of force acting through said retraction device when said folding pontoon boat is in the operating configuration exerts an upward vector on said deck members sufficient to readily initiate upward movement of the inner sides of said deck members. 10. A folding pontoon boat as in claim 1 and including a motor mount mounted in said folding pontoon boat, said motor mount rising, and maintaining a substantially constant orientation, when said folding pontoon boat is being converted to the folded configuration. 11. A folding pontoon boat, comprising: (a) first and second elongate pontoons, each having a front end and a rear end; (b) first and second deck members, each having a front end and a rear end, a bottom, a top, an inner side, and an outer side, each said inner side having a top edge disposed toward the top of the respective deck member and a bottom edge disposed toward the bottom of the respective deck member, said front and rear ends of said first deck member being aligned with the respective front and rear ends of said first elongate pontoon, said front and rear ends of said second deck member being aligned with the respective front and rear ends of said second elongate pontoon, said first pontoon being secured to said first deck member and thereby defining a first boat section, said second pontoon being secured to said second deck member and thereby defining a second boat section, (c) first and second jamb plates secured to respective first and second deck members at said inner sides of said deck members; and (d) a hinge hingedly connecting said inner sides of said first and second deck members to each other thereby to join said first and second boat sections to each other for pivotation of said first and second boat sections with respect to each other, between an operating configuration wherein said first and second elongate pontoons are spaced at a first relatively greater distance from each other and said first and second deck members, in combination, define a deck of said folding pontoon boat, having a common top surface extending between the respective outer sides of said first and second deck members and between front and rear ends of said first and second deck members and wherein the outer sides of said first and second deck members comprise an outer edge of said deck, and a folded configuration wherein said first and second elongate pontoons are spaced proximate each other and said first and second deck members extend upwardly toward the respective inner sides, said folding pontoon boat being free from superstructure above the top of said deck for supporting said deck members proximate said inner sides when said folding pontoon boat is in the operating configuration. 12. A folding pontoon boat as in claim 11, said first and second pontoons being non-pivotally secured to the respective said first and second deck members. 13. A folding pontoon boat as in claim 11, said fir
