I know this has been discussed a lot here. I went over what I did on mine to keep the water out when the last person asked about this.

This past weekend I found a few more sources. Before leaving on a fishing trip I check the forward bilge and it was dry. I had the livewell running most of the day and when I returned I found the water level in the front was up to the point were the bilge switch wound kick on.

Everything in the rear bilge was dry. I pulled off the side cover on the left side of the aft bunk.
I ran the livewell and found almost a steady stream of water coming out of the drain hose at the thru-hull.

The hose was torn between the spirals. This was right next to were the barb fitting starts. I believe the edge of the clamp pushed the spirals apart and torn the hose.

The hose itself is not very thick. This type might be fine for a bilge pump but the drain has a lot of water flowing through when the system is on and there is some weight in the hose.

I replaced it with a heavy clear reinforced hose that is the same type used on the fresh water system.

Now when I was in the compartment area, I found water on top of the foam between the stringers.
This could not have gotten up there from hose leak.
During the day some dead killies clogged the overflow tube and the livewell overflowed onto the deck.
So I overfilled it and watched. Water began to pure into the hull like a waterfall.
Grady does have a lot of sealant around were the livewell meets the upper part under the lid.
I am going to have to get a mirror and check for voids in the sealant.

Also I found the hardtop mounting leg bolts leaking on the left side step.

Hope this helps for anybody trying to track down the source of their leaks.

I discovered the same livewell issue several years back. There were gaps at the top which allowed water to overflow into the bilge. I bought some waterproof silicone caulk to seal it thoroughly all the way around.

I hope GW has corrected this in the construction process as a LOT of seawater could flow into the bilge during a long fishing trip. If the bilge switches failed there could be serious trouble.

Thanks Megabytes.

The entire aft section under the lip pulled away from the sealant. They did no put enough on the vertical surfaces to keep it to grip good. Plus the livewell probably settled into place.

Two tubes of life chalk and the entire underneath is sealed nice now.
