The boat needs to be in service a few hours soon, removal of the water trap was not really what was wanted, the hole is quite small, so what can we close it off with as a temporary fix?
The answer was easy tofind and already on the boat, two large stainless hose clamps were joined to make one that was larger, a spare cork sanding block was the other component, such cork is quite flexible and its also water proof.
If the leak had of been larger a second or third clamp would have been put in place.
A proper repair will be another job for the rainy days?
The run in the bay was about three hours doing around 1600 rpm , the fix worked and not a drop of water leaked out, so another dry bilge day!
