Water in bilge (2007 315)

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I usually have a totally dry bilge except when sailing in 15+ kts when I can get 0.5-1 bucket full of salt water after 5-6 hrs sailing but not enough to activate the bilge pump. I suspected the deck hull joint so tightend the toe rail srcews and put sealant filling toe rail to hull gap. Likewise the transom join. Made no difference. The hull is totally dry/dusty when looking in the speed/depth sensor inspection covers so the ingress is not from the bow or anchor locker.  Under V berth lockers also totally dry  No water under the engine or galley sink either. I removed the cabin sole panel below the companion way and there was a little water in the hull on the galley side of the under-floor webbing(?) that solwly runs through to the main bilge area where the pump is.

Could the saildrive or rudder stock allow the water ingress but only in strong winds/large waves? Is there anywhere else I should be checking?

I have a the wheel steering rather than tiller version of 315.

	I checked the bilge of my 312 (2004 -wheel steering ) last week and sponged out half a bucket full from under the floor boards where the pump is. No worries, I think - I last checked it at the beginning of the season and had since cleaned the speed spin wheel twice-each time some water coming in, of course. (Had been in 1.5 waves only once this season ) My question: Is there a way to ckeck whether the electric bilge pump is still in order and would work if needed?' Thank you Wieland

	It if was the Sail Drive rubbers you will have water in the engine sump. You can check the bulge pump is working as there is a tab attached to the magnitic float - if you lift this the pump shouild start. While you are there, make sure you can lift out the pump filter all the way. I had to reposition my pump as I could not remove the filter as it caught on the floor board! Check the toilet as this can feed back into the cabin bilges. The last look I would recommend is to pull the boards out from under the table to expose the keel bolts.

	If its fresh water look at the calorifier. Domestic water pumps can leak. If seawater check round engine seawater pump, exhaust system etc.

	Also, if seawater, check the heads sink and shower outlets. Unlikely I know, but in our boat they are above water in light winds and can be below water when healed. A leak in the outer seal might then give the symptoms that you describe.

	I had a problem on my H315 2006 where there was saltwater in the bilge after sailing. I checked in a lot of places. At last the problem was found in the transom joint where there was one (1) dry unlaminated fiber strand that passed through from the inside to the outside. It started to leak after some years after the caulking on the outside had worn away. I found it by emptying the aft locker and going motoring. As soon as the transom joint went under water there was a trickle of water coming into the boat. Had to look with a flashlight to see it. Good luck, Mikke

	Thanks for the suggestions, they have given me more ideas on what to check. Sounds like a sail in a strong winds and big seas with my head down the aft lockers trying to find the source is in order. The heads sink and toilet should go to the heads drain and pump rather than the bilge (unless the leak is in the pipework) I would have thought. Please correct me if I am wrong.

	Check the overflow/vent pipe connection to the water tank.This will only leak when the tank has a reasonable amount of water & the boat is heeled over. You may think that the water is salty, but by the time it gets to the point where you can taste it, contamination will make it difficult to confirm if salt or not. Then check connections between pump & tank. After the pump it is easy to tell if there any leaks because every few minutes the pump will start, to equalize the pressure. The other source of salt water is the exhaust pipe under the aft berth. Has it corroded to a point where it is leaking? Same goes for engine hoses, which may have a small split. Typically the inlet hose, which often gets disconnected annually for engine flushing at layup. Mine developed a small split which I missed & it started to drip even though the clamps were tight. But these leaks will generally only happen when the engine is used. Once the boat heels any leaked water will then make its way around the boat. Quite a lot can be stored inside the stringers, which are hollow & only comes out if the boat tips up enough. Sprinkle lots of talcum powder around any area you want to check & it will soon become obvious where the source is Edited by samuel - 19 July 2023 at 08:14
