Re: Big Twin Lower Unit Reseal Question

[Don]

Keep trying to pinpoint the leak in the bucket of water, twist the shafts/pull the shift rod up and down, use the low and high pressure settings as others have described.
PS- I mean no offense, I’m sure you have checked, but does each gearcase lube plug have one, and only one gasket? It is surely easy enough to mix them up putting two gaskets on one screw and none on the other. Have you probed the screw cavities in the gearcase to ensure there are no remnants of the old gaskets left in the holes?
