A method for controlling movement of an armature for an electromagnetic valve actuator. The armature moves between pole faces of juxtaposed solenoid coils. Voltage applied to armature capturing coil is varied in a closed-loop fashion as the armature moves through a flux initialization phase, followe
A method for controlling movement of an armature for an electromagnetic valve actuator. The armature moves between pole faces of juxtaposed solenoid coils. Voltage applied to armature capturing coil is varied in a closed-loop fashion as the armature moves through a flux initialization phase, followed by an armature landing phase whereby a soft landing of the armature is achieved during valve opening movement and valve closing movement.

A housing for electronic equipment in a personal watercraft as in claim 13, wherein the foam includes cavities for at lest partially housing an engine capacitor. 22. A jet-propelled persons watercraft comprising: a hull including a bottom hull and a top deck secured over the bottom hull, the hull defining an engine compartment sized to contain an internal combustion engine for powering a jet propulsion unit, the jet propulsion unit including a steerable water discharge nozzle, the top deck having a raised, longitudinally extending seat adapted to accommodate an operator in straddle fashion; a foam piece disposed within the hull, wherein the foam piece has a cavity therein for at least partially receiving a battery, wherein the cavity has a foam cavity floor; and a battery disposed directly within the foam cavity against the foam cavity floor. 23. A method for housing engine electronics equipment in a personal watercraft having a top deck secured to a bottom hull to form a hull interior within, the method comprising: providing the personal watercraft; providing a foam piece adapted to be disposed within the hull interior space, the foam piece having at least one battery cavity formed therein adapted to at least partially contain a battery, wherein the foam further comprises at least one engine electronics control box cavity adapted to at least partially contain an engine electronics control box; and disposing the foam piece within the hull. 24. A method for housing engine electronic equipment in a personal watercraft as in claim 23, further comprising at least partially inserting the battery in the battery cavity. 25. A method for housing engine electronic equipment in a personal watercraft as in claim 23, the method further comprising at least partially inserting the engine electronics control box in the engine electronic control box cavity. 26. A method for housing engine electronic equipment in a personal watercraft as in claim 23, wherein the foam piece is not attached to the bottom hull using fasteners that penetrate into the hull. 27. A method for housing engine electronic equipment in a personal watercraft as in claim 23, wherein the foam piece is shaped to match the bottom hull interior, and wherein the foam piece fits snuggly to the hull bottom interior without fasteners penetrating into the hull. 28. A jet-propelled personal watercraft comprising: a hull including a bottom hull and a top deck secured over the bottom hull, the hull defining an engine compartment sized to contain an internal combustion engine for powering a jet propulsion unit, the jet propulsion unit including a steerable water discharge nozzle, the top deck having a raised, longitudinally extending seat adapted to accommodate an operator in straddle fashion; a foam piece disposed within the hull; and a battery secured to the foam piece disposed within the hull, wherein the battery is secured to the foam with at least one strap. 29. A jet-propelled personal watercraft as in claim 28, wherein the strap secures upon itself using hook and loop fasteners. 30. A housing for electronic equipment in a personal watercraft the housing comprising: a foam piece adapted to be disposed within a hull, the foam piece having at least one battery cavity formed therein adapted to at least partially contain a battery, wherein the foam includes at least one hole entirely through the foam and opening into the battery cavity. 31. A housing for electronic equipment in a personal watercraft as in claim 30, wherein the foam includes at least one strap disposed through the at least one hole. 32. A housing for electronic equipment in a personal watercraft as in claim 30, wherein the foam includes at least one strap secured to the foam. 33. A housing for electronic equipment in a personal watercraft as in claim 31, wherein the strap secures upon itself usin
