    Default mojo taking on water

    my 2016 mojo is taking on water somewhere in the enginge compartement. it startet to get noticable when i installed the FAE. It's not a big deal but i want to have it fixed because i'd prefer a dry bilge and dont want the pump to kick on regularly.
    it's definitely not a ballast issue. must be somehere on the exhaust hose or anything in that area. anyone had the same experience on their boat and knows how to fix it?

    Inspect the welds on the FAE as well as the thru-hull bolts.

    Those are two common points of entry.

    Yeah, if your boat is in the water....try and wiggle the FAE...if there is play then you probably cracked a weld and snapped a bolt.

    Easiest way to see is pull the engine divider panel and a flashlight....you will see a slow trickle of water coming in.

    I checked the exhaust today and it seems to be dry. I found that pump shown in the picture dripping, like every 3 seconds when engine is on. Is this the raw water pump? Probably more water is coming when driving. Any idea how to fix that?

    That's your heater pump. It would be leaking antifreeze. It is common that the connections leak, just need to be tightened down.
