Hi folks thanks for all the suggestions. I'll make it as short as possible. I purchased a new pump, 4gpm, hooked it up, didn't work, checked breaker switch, wire off, hooked it up, pump ran but wouldn't pump, lots of air, check local area, discovered line going to exterior of hull where you hook up city water leaking. Disconnected that., checked again, same thing, lots of air little water. Checked accumulator, it was bad, I removed it because the specs on the pump did not require one. Ran again, same results. Called plumber, checked water tank and line. Line OK, tanks empty. I had filled them the week before and had not used them. Figured out the breaker must have been on, when the accumulator lost pressure, the pump kicked on, all water was pumped out through the crack in the external water hose line and water pumped overboard by bilge pump and then primary pump burned up or pressure switch gave out. Now the system without the external line and the accumulator and with water in the tank , the system works fine. I could not make this up. Thanks for all the valid suggestions.
