Sierra Gearcase Filler Replacement Hose Assembly 18-99526

The Sierra 18-99526 Gearcase Filler Replacement Hose Assembly is a complete gearcase oil filling kit designed to make gear lube changes on outboard and sterndrive lower units simple and mess-free. The assembly includes a flexible fill hose, a hose clamp to secure the connection, a shutoff valve to stop flow instantly and prevent drips or spills, plus both a threaded tip and an unthreaded tip so it can be fitted to different gearcase filler openings. Constructed from durable plastic and rubber components, the hose resists the oils and lubricants used in marine lower-unit service while remaining flexible enough to reach tight gearcase fill points.

This hose assembly is intended for use as a replacement or upgrade fill hose in gearcase oil-change service, letting the user pump or pour gear lube into the lower unit through a controlled, shutoff-equipped line instead of an open funnel. It is built for the same style of gearcase filler system used with CDI Electronics 551-33-1 Gearcase Filler units, giving buyers a compatible replacement hose without having to replace the entire filler tool.
