Back at troubleshooting my water in the bilge issue. Took a run today and half way through the ride I’m seeing the rear bilge alarm. It was bone dry when we left the dock. It was a bit rough and much boat traffic so I couldn’t get down there to witness it. From what I can see it’s not running from anywhere forward. wherever it’s coming from is in the aft bilge area. What’s back there is thruster, zinc bolts and through hulls. Also wondering if it could be one of my check valves on the bilge pump allowing water back in. As I’m typing this I’m thinking of going outside the boat to pour some water into the outlet to see if it runs back into the bilge.

 

Try this, I took a cruise last week with my engine room hatch open to monitor some repairs and along the way I figured out where my water is coming from. Open your engine room hatch in cockpit and in the rear 2 corners you will see two water drains, well when cruising and NOT up on plane the water splashes against the seam where the upper and lower halves of the boat connect near rear on sides of the boat and the ports for the hatch drains is right there and water is getting punched back into those drain ports and up the hose and was coming out the 2 drains at the hatch.

During my dry bilge campaign I installed some check valve’s in these drains and replaced the rudder seals and now no more salt water in the bilge. Just getting fresh water now so the hunt continues

 

I think I’ve nailed it. Poured some water into the bilge drain on the exterior port side and the water came out of the aft pump. I have 2 check valves on order. Btw I did add check valves to the drains in the cockpit hatch after finding wet carpet a few seasons ago.

 

@AEO @Irie308 can either of you post a link to what check valves you bought?

 

Whale Non-Return Inline Valve - Suction or Discharge Line - Nitrile https://a.co/d/bpqEaQZ

 

Did you use this style on the hatch drain as well?

 

Yes those are the ones I added to the hatch. Also assume it’s used throughout all the bilge lines on the boat.

 

Been getting tired of draining the Port battery bank. Added two more batteries for a total of 5 on that bank. Pretty easy to do.

 

Here is another mod we made...a larger table for more fun!

you can never have too many batteries … ;-)

 

Mine's a bit older boat but it doesn't exist on mine. Looks like someone added it. Can you decipher the writing beside it? Might just have to trace the wiring to figure it out.

 

A quick video while underway to support my hypothesis. Did not understand how low the ass end really squats underway.

That really came out nice! it was fun to watch your posts as the project was underway.

 

My money is on aftermarket
