The butyl apparently oozed out enough for the bedding to become a little thinner.

Is butyl the right application for this, or should I look for a curing sealant to bed the gudgeons? If the latter, what would you recommend?

FWIW, I am replacing the Phillips head bolts with hex head, so in the future I should be able tighten them up mid-season without having to remove the rudder.
This is why I stress over, and over, and over again tighten SLOWLY, WAIT, TIGHTEN SOME MORE, WAIT, TIGHTEN SOME MORE... when the butyl STOPS oozing then the fitting is tight. The larger the fitting the longer the process..... The butyl did what it is supposed to do, the just missed installer a step.. keep tightening until it stops oozing and you'll be fine.
