Yamaha 4hp 4 Stroke
I recently lost the sump oil drain plug from my 2008 Yamaha 4hp 4 Stroke. When I ordered the replacement part/s I was sent a hex-headed drain screw and two slightly differently sized metal [steel?] washers.The Yamaha manual refers to there being a gasket and when I queried this with the suppliers they checked and advised that the metal washers are the gasket. I was expecting a more standard looking gasket? Does anyone happen to know if this is correct and if so which way round the two are supposed to be used? I have been trying to find a parts list/diagram online but can't find one.
