Recently I had chance to talk to dolphin pumps directly. it seems that the marine seal after about a year or so will start to leak/drip on the amp master 3000. a new seal is available and cost about 85 dollars plus shipping if you send it in. it is said the new seal will outlast the pump itself which has a life time warranty. anyway thought i would start a thread on pumps. feel free to just jump in if you have any comments or questions on pumps
