Zodiac taking on water

Andrewdavidhood · 13 April 2019, 21:09

Hi I have just purchased a 1998 zodiac yachtline 420 in good condition. However when I put it in the water the boat started to fill up with water. I think it may have come through the valves at the back of the transom. Certainly a lot came out when I took the boat out the water. Anyone seen this before and know how to stop it? Many thanks

There are 2 bungs/valves in the back of the rib. A lower and smaller screw in bung and one above it the “perko” scupper valve, with a rubber flap. Which valve! is the water coming out of?

Hi Bremar. Thanks for your reply. There are two black valves with flaps which i think are supposed to let water out but not in and the water pourd out of the one on the right. Theres also a small hole with a bung/cap which releases the water when you unscrew it. I think this is how you normally release excess water. Its situated between the two black valves. I have a feeling the black valve on the right is faulty or needs adjusting.. thanks andy

Are they flap valves or mushroom valves

Hi they are flap valves. I might risk sounding stupid here but we,ve just found two plugs that go in the holes on the floor of the boat so that will stop the water coming through. It shouldn’t have filled up so quickly though so I,m thinking one or both of the valves need cleaning or replacing which is something we can do. The excess water should also come out when we plane. Anyway think the problem is solved know but thank you for your replies!

I would look into swapping them out for mushrooms if clean very little water bypasses

Long shot but might work speak to these guys

Thanks ill see how much water it takes on and look into.

Hi,
I use a bung put in place from inside the boat. They are most likely the perko valve. Tho on my zodiac I’ve only got 1. The issue is that the flap gets a permanent bend and doesn’t close properly. If you search on you tube there is a video that shows you how to fix the issue by undoing the 3 acres at the back of the transom that holds the flap heating it with a hot air gun and pressing it flat. It works for a while. The bung always works tho.

Thanks Bremar the flap certainly doesn't look flat so I'll give that a try. Cheers
