The auto drain holes in the stern always let a small amount of water in when sitting still. Anyone know the size plug for stopping them up ? Or an aftermarket supplier ? Thanks

My Dauntless 14 does the same with the 75hp Merc on it. I bought Scupper Plugs from my BW dealer. The are spendy but work well. Since the holes are so close to the floor, I trimmed down one part of the "lip" on the plugs so they fit.

Went to the Whaler dealer here in NC. They sold me 1.5" plugs. Took them home and they were too big. Tried 1.25" plugs from another shop and they were too small. I then wrote to C. Bennett at Whaler and he said they had many different vendors for the scuppers and could not give me a definate answer on the size. Any ideas ? What are these ping-pong ball type scuppers ?

What is the diameter of your scupper holes?? That will tell you the right size. Again, with those on my Dauntless 14, they are located close to the floor for proper draining. Therefore, I had to trim off a small section of the "lip" to align with the floor and allow the plug to fit in snugly.

The holes are somewhere between 1.5" and 1.25". I guess I could use an inside mic, but I have never seen any sold in a range between 1.5 and 1.25. There was no clearance problems with either set, they just didn't fit the hole correctly. I would like to find out more about the ping-pong ball type.

Before you invest in modifying your Whaler by installing a different type scupper, (which you might end up not liking), I would hitch up the BW and take it to the dealer you bought the 1.5" plugs from. Go their service department and tell them you bought the plugs there but they don't seem to fit. Ask them to "give you an hand" in getting the plugs to fit.

You can use a slide caliper to measure the
inside diameter. A handy tool to have around
and the cheap ones from General aren't very
expensive. (<$10 IIRC, it's been a long

Dauntless 15 does allow water through the auto-drain holes. I added two plugs to stop the in-flow. I used Oatey Test Plug #33400 from Home Depot. To facilitate the fit, I removed the smaller plastic tapered ring and replaced it with an 1 1/4 inch dia stainless washer (I had to enlarge the washer hole slightly). Initially, I installed a small Rule bilge pump into the floor well. This posed a few installation challenges but it works fine. Unfortunately the only way to solve the water problem is to plug the drain holes, but you may also want the bilge pump if your boat sits outside.

Hope this helps.

I made some drain plugs for my 13 Dauntless out of tapered rubber plugs, washers, and bolts with wing nuts. All parts were purchased at a local hardware store. It was simple and works great. email me at if you want more info.

Thanks Jim and Roger. I will look into both fixes. Dick M.
