Abstract: The integrated bell housing on an engine, carries a supercharger, an alternator, a water pump and a starter. The engine has a crankshaft which is coupled to a flywheel in the casing as is a geared transmission. The flywheel has a first gear and a second gear. The first gear drives a supercharger drive shaft which drives the supercharger. The second gear is coupled to an alternator drive shaft such that the flywheel drives the alternator. A water pump drive shaft is keyed to the crankshaft and is rotatably mounted through the bell housing.

Abstract: A drive apparatus (12) for a boat having a planing hull (14) including a notch (24). An engine (30) and a transmission (32) are mounted within the hull. A propeller shaft (38) is connected to the transmission with a universal joint (34) and extends rearwardly therefrom into the notch. The propeller shaft passes through a shaft support (56), and a propeller (46) is affixed to the propeller shaft behind the shaft support. The shaft support depends from a strut (58), which is mounted on the underside of a pivot arm (50). A trim drive (62) is mounted within the hull and above the notch and the pivot arm. A linearly extendable trim drive shaft (64) extends between the trim drive and the pivot arm and, when the trim drive is actuated, pivots the pivot arm, and thus the propeller, selectively upwardly and downwardly to adjust trim for maximum drive efficiency under various boat load distribution, water surface and wind conditions.

Abstract: A planing hull having a conical contour extending from the bow portion to a stern portion having a flat surface on each side of the keel, a wide lip chine having a lip portion, and a transom separating the bow portion and the stern portion creating a step between the bow portion and the stern portion. A flat keel portion extends from the stern to the mid hull transom.

Abstract: A stern drive for an inboard engine mounted in a boat, the stern drive having all of the sensitive bearings inboard of the boat to protect them from water damage, and a screw type trim system mounted on the inside of the boat transom for raising and lowering the stern drive to adjustably trim the surface of the drive unit.

Abstract: A surface effect vehicle having a pair of lifting scoops, or air foils, mounted on a vehicle body, one in front and the other in the rear. Each lifting scoop has an arched leading edge to collect air under the scoop to lift the vehicle on a cushion of air. The vehicle having a pusher-type engine with a propeller to push the vehicle. There are louvers in the lifting scoops to regulate the height the vehicle travels on a cushion of air, and non-trip appendages on the tips of the lifting scoops to aid the scoops in lifting the vehicle from a surface.

Abstract: A bow anchor system which has a configuration of the bow of a boat to fit against the bow. The bow anchor has a triangular shape with a pair of wings which form a delta shape. An arm pivotally connected to the triangular shape is also connected to the anchor line for raising and lowering the anchor. A winch mechanism in the hull pays out and retrieves the anchor through a conduit in the bow of the boat.

Abstract: A planing boat hull having a conical contour extending from the bow portion to the stern for a distance equal to substantially one-third the length of the hull at the keel and two-thirds or more at the chine, the after section of the hull consisting of a flat surface on each side of the keel maintaining a constant dead rise angle of 12 to 18 degrees extending to the wide lipped chine, and a chine lip portion extending at the same angle as the dead rise but in a reverse direction.

Abstract: A water propulsion device for boats having a plurality of housings bolted together so as to be partially submerged in water requiring no lift and a minimum of drag to the water passing horizontally therethrough. A shoulder on each side of the housing prevents water from flowing over the housing. A vertical wall in the housing divides the water into two jet streams whose reactive forces are imparted to the boat, each of which water jet impinges on an arcuate deflector plate to effect the steering of the boat. The steering mechanism consists of a slide bar whose position determines the forward and rearward movement of the boat while a cam plate and turn arm cooperate to determine the turning moments of the boat.
