Hi Friends.
I come to you to ask you for advice because I have Oil loss Base transom by axis Drive shaft oil seal on Yamaha Hydra drive DE-DHD
Ref Engine: Yamaha ME420STI
After replacing the joint "33" several times on the attached photo I still have a persistent oil loss.
Has anyone ever had the similar problem?
Or anyone to give me advice to resolve this problem?
Thank you in

Welcome
Don't know your motor but with the seal leaking after replacement would tell me that the bearing holding the shaft is most likely the issue. There is most likely to much play and the shaft is moving laterally
