Last summer I replaced my front air with a marine aire system, I also replaced my water cooling pump with it with a 500gph. The old pump handled front and rear air. This was original equip (1997 ). The marine aire sales man said it would not handle both units so I put a y on the water coming from the thru hul (3/4") and put 2 -500 gph pumps. I cannot get one pump to draw water even after priming. My question is, the tru hull is 3/4 so can that provide enough water for both pumps? Or is one pump bad? The one that want prime, gets very hot. I wired both pumps together, so I assume both pumps will run when either unit calls for water. Today my old a/c unit keeps,kicking the breaker so I assume it's going out now. Help need advice
