It is designed to reduce friction and protect gears, bearings, and other gear case components from wear and corrosion during all standard marine applications. The lubricant has a viscosity of 75W-90 or 80W-90, matching the requirements of most marine lower unit and gear case applications, and comes packaged in a plastic bottle for clean, controlled pouring at the fill and vent plugs.\u003c\/p\u003e\u003cp\u003eThis gear lube is part of the Sierra 18-9600 line and is sold in two sizes to match different service needs: a 10 Oz tube sized for topping off or a single small gear case fill, and a Quart bottle sized for a full lower unit gear lube change or keeping extra lubricant on board for routine maintenance.

The integrated magnetic tip is the key feature of this drain screw: as fluid drains from the engine housing, the magnet collects metal shavings and ferrous debris, giving a quick visual indicator of internal wear each time the screw is removed. This makes it a useful upgrade over a plain, non-magnetic drain screw for routine maintenance and inspection. The screw is compact, measuring 0.39 x 0.39 x 0.39 inches, and is built for use as a drain plug on applicable outboard and stern drive engine housings that accept the OEM 318544 screw. As a Sierra part, it is manufactured to fit and function as a like-for-like replacement for the original equipment screw it replaces, and is backed by Sierra's customer satisfaction warranty.

This 1 quart bottle is sized for topping off or partially refilling a jack plate hydraulic reservoir, and a completely empty system with standard hoses will use about 1.5 quarts to fully charge. Using the ISO 32 AW grade that the pump manufacturer calls for helps maintain proper lift and lowering performance and reduces wear on seals and internal pump parts compared to using an off-spec fluid. Part number 120-301003 is packaged as a single quart, making it easy to keep on hand for routine maintenance, seasonal fluid changes, or bleeding air out of the system after service work. Whether you are performing a full fluid change, replacing fluid lost during hose or fitting repairs, or simply maintaining fluid level as part of scheduled boat maintenance, this hydraulic oil is
