Abstract: A device for supplying an alternate gas fuel to a gas-burning apparatus such that the gas-burning apparatus will receive and burn the alternate gas fuel, the gas-burning apparatus being of a type intended to burn a gas fuel which is different from the alternate fuel and is supplied at a pressure substantially different from that of the alternate fuel. The inventive device comprises: an inlet coupling attachable to a discharge fitting provided on the alternate fuel container and an outlet coupling downstream of the inlet coupling and attachable to an inlet fitting provided on the gas-burning apparatus. When the pressure of the alternate gas fuel is significantly greater than that of the intended fuel, the inventive device preferably also includes a restricting element for restricting flow of the alternate fuel through the device from the inlet coupling to the outlet coupling.

Abstract: A shift speed equalizer is provided in a marine transmission in a marine drive subject to a decrease in engine speed upon shifting from neutral to a forward or reverse gear due to a high propeller pitch or the like, such as in bass boat applications, and subject to an increase in engine speed upon shifting back to neutral. The shift from neutral to forward or reverse is sensed, and engine speed is increased in response thereto, to compensate the decrease in engine speed due to shifting. The return shift back to neutral is sensed, and engine speed is decreased in response thereto, to compensate the increase in engine speed due to shifting. Engine speed is increased by advancing engine spark ignition timing, and engine speed is decreased by retarding or returning engine ignition timing to its initial setting.

Abstract: A marine carburetor is provided with an adjustment screw mounted on the throttle lever that is engageable with the cam follower in such a manner that movement of the adjustment screw urges the cam follower into engagement with the surface of the throttle cam, at which point continued movement of the screw results in movement of the throttle lever so that the throttle plate may be adjusted to an idle position.
