Re: Gray matter
Where does this gray oil come out at? Behind the prop? Out of the exaust ports?<br />Idling all day will create abnormal amounts of unburnt fuel/oil mix. It should noramlly foul the plugs more often than usual too.<br />Impeller wear is higher then normal if an outboard only idles. This is due to the vanes making constant contact with the pump housing walls. Not a biggy, but the impeller is a wear item to begin with, which is why I brought it up.You may want to change it every season.<br />To make sure your lower unit is ok, check it at the vent screw,using a pipecleaner like a diptick. IT should be full to the top, and translucent olive green,or brownish green.<br />If it is gray, you have a bad seal in the lower unit....Either prop seal,driveshaft seal, or both. Always remove the old screw gasket, and use a new one each time you check it.
