Scuppers

post #1 of 15
Thread Starter 
I have always used the flap type scuppers on my boat and replace them every year or two. They will usually let water into the little splashwell when the boat is anchored or sitting at rest in the slip. Was thinking about switching over to the silly looking ones with the ping pong balls inside of the but am not sure.
Any scupper insight ?

Silly looking ones.

You just need to paint them inside because barnicles will grow inside them and hold the ping pong ball back from sealing the drain.

They work but water still gets in .

I have seen a number of folks with more problems with the ping pong ball variety, than the flapper. My sample is small, so it may not be that accurate.

Flaps on scupper are not designed to keep calm water out of a boat when at rest, they are to keep large quantities of water from getting in when hit from behind by a wave , or while backing down.
If your splash well floods while at rest, either the boat is designed poorly, your engine is too heavy for the boat's design, the weight of it's contents are not stowed well, or all of the above.

Well I just bought a hobie skiff that had its self bailing holes filled in and painted over. I thought maybe they just were patching over so they could paint the transom. So i just drilled 1 inch hole and have the ping pong style scuppers on order. I read bad things about the flappers, but now im starting to see the same on the crap that i just orderd. I will be fishing mainly a calm river and the boat will be sitting in water when im not using it.
Was this a good choice or should I just patch them back up and invest in a good bilge pump??

I have no problems with the flaps on my boat. Water will come in the scuppers at times, but it never hits my deck because there’s about a 2 inch deep by 4 inch wide well that sits between the deck and the scuppers – water goes into the well but drains back out the scupper. Many a boat has the scuppers sitting on the deck – poor design IMO.

Depending on the height of the deck relative to the water level.

^^^^ That is true.

I've seen too many 20'-25' CC (especially Scout's) at my marina that have the scuppers on the deck, and they are hanging large, heavy, fours stroke outboards that puts their deck at or even below the waterline. As a result they are often standing in puddles. My boat is setup similarly (max HP rated for the boat with a 4-banger), and if it weren't for the well, I'd have puddles as well.

Many of the manufacturers have resolved these issues with the increasing popularity of 4-strokes, but there are many late 90's early 2000 boats that are having these problems.

I had a friend with a boat that always required boots when you were on it.

I had deck scuppers on my HydraSports (with the flappers) and in the 8 years I had the boat, I don't remember ever getting water in them.
Prior to that I had a 1980 Aquasport with Deck scuppers, with no flappers and never got water in that way unless there were three of us standing in the same corner, and then it was no more than an inch.

I see what your talking about , those boats that have a small resivour for overflow. I myself do not. I migt just fabricate something with fiberglass to make one. that sounds like the best option.. another thing, I hear alot about the nosie these things make.Are people blowing this out of proportion. Are will it be a nice ticking nosie like that of a popper or something. Sorry for all the questions, I just really want to know before I mount these ping pongs!
thank you

The difference here Wayne, is you actually think about things, and you know how to set up a boat!

some flappers are better than others, I changed mine on my 27' Eastern to "sea stop"
they are solid plastic rather then rubber and work great.

I will be installing the Tempo autodrain plugs this spring and will see how well they do.
