35 EX water in bilge
 

Hey guys, every EX I've owned or been on has accumulated water in the bilge ( all 2006 and 2007s ). My previous lightning was pretty much dry as a bone. Any insights on where it might be coming from. In two previous boats a lot of the problem was from loose exhaust clamps. Tightening slowed it down, but the water still finds a way to get in... Thanks in advance!

Just check all water connections. Strainers, exhaust, coolers, block drains. Also check any under water thru hulls.

is this after being on the water on a dry day or accumulated over time? The vents will let water in if not covered in rain. Also wind screens, bow rails anything mounted can leak. Sealant has a shelf life and needs to be redone after time

Starts out dry. I've actually left it on the trailer dunked it and started it up...nothing, but after running it awhile, water always accumulates. Seems to be more on the starboard side. Every executioner I've been in has done this to some degree. After rafting up for a couple of hours, I'll hit the starboard bilge and get about 10 seconds of water... I wonder if this is why Executioners are notorious for stringer issues...

All the rubrails were replaced, not sure if they were sealed properly. Can't imagine that much water getting through there in that amount of time though.

If it’s leaking just sitting it’s a below water thru hull most likely.

think drive cutouts, water pickups, trim tabs, garboard drain. If your head has an overboard discharge/pickup. Things along that nature

There are two vent holes on the starboard side. The upper is were the bilge water comes out. What does the lower do?

It would be below the water line.

Don’t know without pics. Follow the hose and see where it goes

If it’s a 496 engine boat, check the water drain actuators, they’re known to leak from time to time

I always had water in the bilge after running my ex 27 Fever, spent a lot of time trying to figure out the source. It turned out being the seal of the deck and hull at the swim platform. There is no access to glass that area so the factory only use sealant.
I suspect the construction of your 35 is the same as the 27.

same construction but the 35 sits higher. I know 32s have that issue but their platform is touching the water at rest. 35 has a couple inches. Worth a check though

Look behind the motors down into the transom assemblies. You could have a swivel pin seal leaking in your transom assembly.

There is alot of turbulence at the stern when running at speed. Water was deflected upwards and made its way in to the bilge when going above 50mph. I only found out when leaving the hatch off the boat and sitting in the bilge when my dad was running the boat.

I get that. Maybe I misunderstood. He has it coming in while sitting still. That would negate that joint.

The top and bottom aren’t glassed together along the back and they all leak and vibrate and make noise. Take the rubrail off around the swim platform. Clean up the joint drill some holes for big pop rivets. 5200 the **** out of it and pop rivet it together. Then 5200 your rubrail screws when you put the rubrail back on.
