For years I have been trying to figure out why after a heavy rain I found water accumulating in bilge area adjacent to transom. I was told it came from the rear sink, the cup holders or around the trash bin. All were incorrect. The source of water was the poorly mounted swim platform. I know this because in having my hull repainted they found evidence of water seepage when they removed the swim platform. I am posting this because if any of you have a similar problem this may be a solution and prevent further damage to your transom. I hope this is a help. Jerry Geisenheimer
 
I too have wondered where the water comes from. I am curious why "after a heavy rain" would cause the swim platform to leak more? I can get all the water out of the two water holding areas but as soon as I wash the boat they are wet again. They remain dry until it either rains or I wash the boat.
 
In my case the leakage occurred around the fasteners which were replaced and recaulked at the time of the painting.
 
Hello

I've just found out after a month of trial and error where rain water was getting in.

I've been removing vee-berth headers, wall covering, checking the outside stanchions bases and the rubrail etc.

All very frustrating, but finally I found the source of the leak.

It was the "walkway" lighting fixture!

The plastic had deteriated and every time it rained water got inside and over time caused extensive (black) mold damage and what water didn't get soaked up by the vee-berth mattress simple drained into the bilge where it automatically got pumped out..

I checked the other three walkway light fixtures, there are four on an R25, and found a second one with the plastic cracked and broken, causing water damage to the cave mattress.

These lights are 3 years old and two out of four were defective!

Check your light fixtures on the transom and maybe this is where that water is getting in.

Good luck, Bob
