I’ve finally found the cause of the last water leak that was in my NC895. But I’m getting ahead of myself. The 695’s, 795’s and 895’s are designed to have a dry hull. My 695 never had a single leak or a bit of water collecting in the hull. My 895 was a different story. Water collected in the bottom of the hull near the stern and under the cockpit area. It also collected in the area forward where the windshield washer tank is located. All of the water was fresh water. Within the first 6 months l located all the leaks in the aft area of the boat. They were all from rainwater or wash down coming in through unsealed or improperly sealed screws, latches, access panels, flex tubing, and the cockpit door to floor seal (or lack thereof). Good news is once I identified them the Sundance folks fixed them under warranty. But The water that was collecting under the windshield washer tank really had me stumped. Well I finally figured it out. The water is coming from the water heater safety pressure release valve. It has a slow leak when the system is pressurized. The valve has a rubber hose that takes any water from the valve to the area at the windshield washer tank. The rubber hose goes directly to the back of a bulge pump that’s next to the windshield washer tank. It’s hard to see the hose but it’s there. This makes sense. If the safety pressure valve detects an over pressure situation it opens and the water is directed to a bilge pump so the pump can extract it from the boat. I haven’t yet replaced the valve on the water heater but fortunately access to it is easy. So why am I describing all this? If you don’t have a dry hull there is a reason or perhaps multiple reasons. And it’s worth the effort to find and fix the leaks. Water in the bilge can over time lead to mold and mildew and adversely affect components mounted low or in that water.
