[Public-List] Cockpit drain fittings--bigger could be better

[John Birch via Public-List]

When we changed those glassed in cockpit pipe drains, we bored out the tube 
out of the hull to the correct flange size and installed Grocko lever action 
full bodied/full bore seacocks and through hulls with backing plates.

Pricey, but worth the cost as there is no constriction at the cock valve.

Best of luck.

Cheers,

John
