So I replaced our water pump right after we bought the boat a couple months back. *Old one worked for about a week and then it died. *New one is working well but I have noticed it seems to pulsate. *If you turn on any of the sinks, water flows good overall but it will pulsate as the pump kicks on for a moment, then off, then on, off, etc. so that pressure is variable. *Anyone else have this issue and what caused it? *All previous boats would run consistent pressure when sink or shower was turned on for a prolonged time (i.e. washing dishes or taking a shower) vs. pulsating pump turning on and off and creating pulsating water pressure. *
