Two additional photos. The first photo is from my boat and shows the water coming in through the hole. The second photo is from an eBay listing, where you can clearly see the hole and it's location to the right of the water tube, directly above the gimbal bearing.
Anyone know what this hole is for? What does it mean when water is pouring out of it? The service manual says nothing about it. I'm constantly having to run my bilge pump. Thanks.
