got a pss dripless shaft seal shitbox on my 31' morgan noticed the thing is leaking and flinging seawater around in my engine room. not leaking from the bellows but cant get the piece of crap to stop leaking aroung the collars. thinking im gonna have to pull off the coupling to remove it and replace it with a traditional packing setup not looking forward to dealing with cutting or pressing it out havent figured wich method is better? heard the socket and bolt technique could damage the tranny flange, cutting with a grinder can damage the shaft. either way im assuming i need a new coupling, does replacing an old coupling with a new one usually go smooth or will i likely run into issues?
