I don't know, maybe drain plug not in?? Heavy rain ??
Where do you keep the boat?? On a trailer?? In the water??
Do you have a bilge pump??
Do you live in the US?? Are you on a Lake?? Are you on a river?? What year is the hull?? What model??
Maybe alittle more info might be helpfull.

See ya, Ken

You changed the through hulls . . . including the scupper tubes? Mine leaked about 3 gph . . . until I replaced them.

My scuppers leak now. Maybe 10 gallons per hour total. I haven't been able to find 6 1/2" brass tubing, though. What did you replace yours with?

Plumbing supply houses carry long brass tubes that are the right size. They were used for stand pipes in older toilet tanks.

Fr. Frank - I posted a scupper repair procedure w/photos back in June. The leak rate you describe sounds similar to mine, so one or both of the wooden blocks surrounding the scupper tubes may be rotted out. One side was rotten on mine. Local Boat Owners Warehouse was able to get brass tubes for me w/overnight order. I just used tapered socket/threaded rod/nuts & washers to flare the tubes. Denny

I replaced several on my old Whaler. You need to anneal the ends of the brass before flaring. A quick heating with propane torch and submerge in water 2 or 3 times does it. It may split if you don't.

The old tubes were replaced with extra long bronze thru hull fittings with nuts and bedded in 5200 every one including boat drains in well I have rear deck up and live well full for a week and thats not dripping into hull, perhaps bow gets hung on bulkhead cuasing stern to sink ?

ken boat is on a bay in a public marina boat slip is tight 1978 23 with 200 yamaha raised boat took to marina lifted decks for a week checked every day not a drop put boat back in marina found rolled over a month later the only possible lead Iknow is that with 2 men on rear by outboard well the water will come over transom and up thru drains.

Bigshrimpin, and Fr. Frank hit the nail on the head.
You have to look at those tubes.
Also get all the weight you can out of the back of the boat. IE: Batteries, gear, etc...
Good Luck, Ken

PS: Frank, I will check Surplus Unlimited, they carry
long brass stock for the tubes. I have the flairing tool
for the ends.
