      May 24, 2019 at 9:31 am Hi ! I have two 1991 Hurth ZF 63A in my Wellcraft 33 Sports bridge on the back of 7.4 Bluewaters. I’ve tried tightening the filter covers that have large O-rings on them. I cleaned them good, and they still leak once and a while, making a mess in the bilge and oil sox. I’ve just ordered two new filters and O-rings, and will try that. Just not sure why it keeps happening !!???? Help ! Bob – In Boston !
