Have a 2008 Yamaha 4hp 4 stroke F4MSH-0608 and I can't find the crankcase oil drain plug gasket part number on the IPC. The manual says to replace it when changing the oil. I found 90201-08818-00 "washer, plate" for $5, but that looks wrong, since it shows a double washer (odd) and $5 for a fiber or aluminum drain plug gasket is absurd. Anyone know the number? I need to order all the parts and materials before heading out to where the engine is stored. Thanks. -Rick
