FAQ

Why are there 2 lower unit drain gaskets included?
Most Yamaha lower units use one gasket at the drain screw and one at the vent screw, so you can replace both during the same service.

Do I need the 10-micron fuel/water separating filter if I already have the primary fuel filter?
They work together—the separator helps remove water and fine debris before fuel reaches the engine-mounted filter.

Can I reuse the gear lube pump?
Yes—clean it after use and store it for future lower unit services.

Should I replace the oil drain gasket every time?
Yes, replacing the drain gasket during service helps maintain a proper seal after reinstalling the plug.
