There has been lots of talk about the factory flapper scuppers leaking on D15s if there is alot of weight in the back of the boat. Mine did too.

I replaced them with teh Rabud 1" scuppers that have a ball that plugs the hole. They work perfectly. They also are a perfect fit and can be screwed in the holes from the original devices. Took me a total of 5 minutes to replace both of them.

Here is the link to the BoatUS catalog. These are the Rabud Sea Scuppers, the 1" ones worked for me.

Do you happen to have a picture of them installed. I can't quite visualize where they go and what they replace. Do they tend to get clogged easily, I end up with a lot of dead leaves/pine needles/etc washing down through the scuppers after my kids track them in the boat. Assume flapper scuppers you mention are same on Dauntless 16 as 15.

I had a similar problem with my 95 Dauntless dual console 17. I complained to my dealer and Whaler paid to put better ones in. They work much better but not perfect. Flaps are inset instead of totally external.

I don't have a picture, but they mount on the outside of the boat. You remove the flappers (in a plastic ring with 4 screws surrounding the hole) and put the ball style in place. I just used the same screw holes, so that they drain hole is rotated a few degrees but then I didn't have to drill new holes.

these things are pretty cheap. in this way, you could get them, try them out and see if they would work for you.

they will clog easier than the flapper style, but the flapper style gets things trapped between the flapper and the edge of the hole so neither is perfect that way. You could mount a stainless screen over between the ball scupper and the rear of the transom using the same screws and stop that from being an issue.

They work great, extremely dry.

I had the same problem of scuppers leaking in on my D15. I "added" the rabud ping-pong type scuppers and they work very well. I do get some water in the boat but its very little.

The only trick with my install is that I sealed the new scuppers on top of the old flapper ones. I didn't have the 4 screw holes John was talking about and didn't want to remove the old scuppers (thru-hull) and drill new holes for the scews. So I just sealed them right on top with lots of silicon sealant. Works real nicely.
