Advise needed for self draining deck

Hello everyone

Back again for some advise on self draining deck.
After finally deciding on a 40hp two stroke outboard for my still unnamed and unidentified rib, I took it for a test run in Aug down at teignmouth where it performed very well.
My only suprise was the deck did not drain when I removed the bung from the transom as we were motoring along.
I am wondering if the bung is in the wrong position on the transom,does any one have any idea's why it did not drain.

Thanks in advance
Lee

Is hard for me to see on the pics, but is there a one way valve type bit of rubber in the hole, that could be installed backwards?....

In that case - maybe the boat needed to be going quicker to drop the water level on the outside of the transom ?

I've similar on one of my boats - I need to be doing about 10knts for it to work, and thats with just a clear hole and no plastic in the way .

When i pulled the plug I was doing about 30 mph and it did not draw the water out and as I slowed it let a hell of a lot in. At first I thought the strainer was blocked but it was'nt. I am thinking of either putting in a new larger bung or may be fitting a hand pump.
Another idea was to put the drain lower down in the bilge and cut hole in the back of the deck so it will drain both bilge and deck as I do not know if there is any water below the deck .

If the plastic strainer has a small middle hole, you are missing the central round diaphragm. It's a one way thin diaphragm with central pin. If that's the case, buy a standard Zodiac type, should work well.

Once inserted on backward valve, central pin must be facing bow. Is there a round plug covering outside water valve ? Buy one if it's missing too.

Happy Boating

That looks like it ,I guess the diaphragm is missing in mine.
That would explain the water coming back in but why did the water not drain away when i was under way.

Could just be the holes (through the strainer) are so small they slow the water so much its hardly noticable that it is infact going out ?

Its not under 'pressure' as such ...have you tried the trailer test - put some water on while its sat on the trailer and see how quick or slow it comes out ?...the slowness may surprise you.
