Never knew that the one on mine must have been removed. It just had a normal plastic bung

My Valiant DR 490 did not have trunks installed. It has a 50mm hole with a rubber flap which worked to let water in or out of the boat. I replaced it with the trunk from the rub shop and now I have comfort in knowing that I can ship a large amound of water if required. It is a small rib thus one of these is sufficent for me. I use the boat of the west coast of Ireland where the sea conditions can be a bit lively

My old SR didn't, and had I not exchanged it for the Humber, It would now have a set! Humber had one and the other blocked up for a 'leccy pump. Suffice to say the second one has now been reinstated.

They have the advantage that they work as long as you are moving, and as said can dump a lot of water very quicky. Usually a good idea to run the release (lift) line to the console so you can work them at a moment's notice. Just my opinion, but the short cord & jam cleat on the transom is one small step above a chocolate fireguard.......
