ABSTRACT:
An air intake installation for the carburetor system of an outboard motor is in the form of an elongate duct e.g. 9, 13a, so configured, located or equipped as to prevent water reaching the carburetor system even if the vessel capsizes. Preferably, a tube 9 (flexible to permit steering or tilting the motor) communicates with rigid under-deck elongate buoyancy spaces forwardly open at 14 and optionally gravity-valved at this open end to close on capsizing.
