Electronically Controlled Marine Jet Propulsion BEFORE WHY CAN’T A BOAT BE MORE LIKE A PLANE? Or a car . . A refrigerator . . Or even a washing machine? All of them are more energy efficient through the use of electronic controls, like the Variable Marine JET Fixed Jet —- Korean War Vintage F-86  No controllable features  Top Speed Configuration Like conventional marine jets Planing Speed Configuration AFTER Efficiently Converts Power to Thrust under Varying Loads and Speeds Low Speed Configuration  High speed capability  Higher thrust at low speeds  Much higher fuel economy at lingering and cruising speeds  More load carrying capacity  Greater safety margin getting up on plane  Longer range  Efficient reverse flow — no reversing bucket  Back off beach without big noise, dredging holes, ingesting debris Coanda Effect Low Speed Reverse First Variable Jet —- 1960’s SR-71  Controllable inlet  Internal flow controls  Works with all common motors, including hybrid and electric  Controllable nozzle  Microcontroller easily slaved to autonomous controls  Like variable marine jets  Greater freedom in hull design for shock reduction  Controllable pitch propeller  Continuously variable power transmission  Optimum engine efficiency and motor life As a result of the Coanda Effect reverse thrust flow clings to the bottom of the hull so it does not disturb the debris, nor dredge it up into the inlet to damage the pump, as is common with reversing bucket designs.
