PWC Parts Co Yamaha Yamalube Gear Lube Kit for Twin Outboards — 2x SAE 90 Qts, Pump & 4 OEM Gaskets

This PWC Parts Co kit contains genuine Yamaha Yamalube SAE 90 gear lube, four Yamaha lower-unit gaskets, and a lower-unit oil pump—everything needed to service two lower units on compatible Yamaha outboards.

Whether you maintain a single outboard or a twin setup, using factory-spec fluids and sealing components helps preserve gearcase health and reliability. This kit bundles Yamalube gear oil quarts, Yamaha OEM gaskets, and a pump with the Yamaha adapter so you get the correct parts for many 2-stroke and 4-stroke Yamaha engines without sourcing items separately.

Which Yamaha outboards will this gear lube kit fit?

This kit fits Yamaha 2-stroke and 4-stroke outboards that specify SAE 90 (standard) gear lube. It covers a broad range of four- and two-cylinder models commonly used on recreational boats.

• Compatible with F15, F20, F25, F40, F50, F60, F70, F75, F90, F115, F150, F175, F200, F225, F250.
• Works for models that call for Yamalube SAE 90 lower unit oil.
• Not recommended for V8 F350, V6 SHO, or 4.2L Offshore motors—those require different lubricants/specs.
• Great for twin outboards: includes four OEM gaskets to service two lower units in one visit.

What exactly is included in the kit and why each item matters?

The kit combines lubricant, seals, and a dispensing tool so you can perform a proper lower-unit service. Using OEM parts reduces the risk of leaks, helps maintain gearset protection, and simplifies fluid changes.

• 2 x Yamalube SAE 90 gear lube quarts (ACC-GEARL-UB-QT) for correct viscosity and gear protection.
• 4 x Yamaha OEM lower unit gaskets (90430-08003-00) to ensure reliable sealing after service.
• 1 x lower unit oil quart pump with Yamaha adapter to make filling quick and clean.
• Packaged for twin-outboard service—enough gasket material to replace two lower-unit gaskets.

How does using OEM Yamalube and Yamaha gaskets affect performance and maintenance?

Factory-recommended fluids and seals are engineered to match the materials and tolerances of Yamaha gearcases. That compatibility helps maintain gear temperatures, prevent premature wear, and minimize the chance of seal failure or contamination.

• Yamalube SAE 90 is formulated for correct film strength and pressure protection in Yamaha lower units.
• OEM gaskets fit precisely, reducing the need for sealant or aftermarket adjustments.
• The pump adapter lets you fill without introducing air pockets or spills.
• Using OEM parts supports consistent maintenance records and easier troubleshooting later.

Who is this kit for? If you own or maintain recreational boats with Yamaha outboards listed above and you prefer using manufacturer-specified parts, this PWC Parts Co kit is a practical, time-saving choice. It’s aimed at do-it-yourself boat owners, marina technicians, and service pros who need a ready set of genuine Yamalube oil, official Yamaha gaskets, and a compatible pump. Avoid for large V8 or specialized SHO/Offshore Yamaha engines that require different lubricants.
