ABSTRACT:
A hydrojet boat drive for efficient transition from low to high speed boat operation, characterized by a conventional drive pump unit and prime mover installation in the "slot" of a "V" bottomed hull and featuring a low drag ram-scoop with a blow-in door or panel which is responsive to imbalance between internal flow pressure and external slipstream pressure, whereby intake volume is augmented for low speed operation and ram pressures contained for high speed operation.
