Built-in tank containing lubricant or the like for outboard motors

摘要

A lubricant tank arrangement for an outboard motor wherein the lubricant tank is contained within the protective cowling of the power head but its closure cap is accessible directly through the protective cowling. The closure cap is recessed and a sleeve is slidably supported in the neck and is movable between a retracted position and an extended position so as to facilitate filling. An improved sealing arrangement is also incorporated between the cowling and the filler neck so as to prevent the ingress of foreign materials into the interior or the protective cowling through the opening which affords access to the filler neck.
