rear hatch leak

my rear hatch leaks when it rains.. mostly because the water pools up in the channel around the seal.

there is a drain, and its not clogged.. the issue is the drain is ineffective because its on the wrong side.

what is the procedure of adding an extra drain? i feel if the drain was in the front, it would not leak..

i just replaced the rubber seal.

here is a pic

We’ve added an additional drain. I used a flaring tool on a piece of 3/8” by 1.5” copper tubing. I then drilled a hole in the bottom of the channel. I used a counter since to bevel the hole so the flare was flush with the bottom. I attached the “drain” to the channel with epoxy. It was a little trial and error to get the height of the flare right. Then I added some tubing and diverted the water into the bilge.

Sometimes abrupt changes in the trim of the boat can do this - when set from the mfgr, the boat might have sat differently.

Also, certainly make sure the existing drain is very clear and clean - sometimes even if it isn't at the lowest point, it will (should) at least absorb overflow from that lowest point.

aaron, Yours looks much like mine. I think the PO added a fwd drain on the stbd side to solve this issue.

Great solution, Larry. My fwd drain snapped off this summer so I need to replace it. I'll try your technique. I plan to use the largest hose feasible to minimize the clogging I have regularly experienced over the years.

I like your method.

You can get flush mount thru hull fittings down to 1/2" not sure if the channel would accommodate one but worth a check

I Tee'd the second drains. 2 of them, one on each side, into the discharge line from the original drain, so rainwater all goes out the transom.

Instead, I would recommend bronze or chrome. Even the new non-destroyable 'plastic' I have have seen them broken which left a hole in the boat until it was replaced. SHRUG Your boat, you do whatever you want.

I could agree if used as a true thru hull but in this case it's a deck drain and worst case the rain water drains into the bilge which its already doing according to the OP???

I had an F32 Trojan that had plastic through hulls above the waterline. I assumed that they were junk and since it was a 1978 vintage boat I was sure they were at the end of life in 2011. I thought I would just smack them with a hammer and they would shatter. Wrong, I could not break them with a hammer no matter how hard I hit them. Finally took a multi tool and cut them off. I was amazed how strong they were and how well they had endured. I still put metal ones in their place though...
