Before we start taking things apart...can anyone tell us what goes on inside the packing gland and rudder tube . We have a leak around the brass sleeve that extends down from the gland into the fiberglass rudder tube when under full power . I am glad we left the inspection panel off so we could easily keep an eye on this area with a flashlight ! " AU NATUREL " is a 1984 C30 #3698 . Any and all help appreciated .
