I have reviewed several Saltwater WD systems: Seaflow, FlowJet, Jabsco, Johnson, Surflow, etc. None have 5 star reviews and I have yet to find one made in the USA. It seems that the reviews indicate that if the pump last the first season, they will last about two more. Some people mount pump motors horizontal. If they leak, the motors usually get drenched in salt H2o and fail. Unfortunately, many boat owners do not have the best available location on their boat to mount these pumps. Seaflow advertises a Salt WD 70 PSI kit for about 120 bucks and guarantees it for four years. At that price, and if the warranty is correct, it sounds like the best deal. .Has anyone mounted a Seaflow 70 PSI pump on their boat?
