Stainless Steel Heavy Duty Drain Bung | Square-Cut Thread | JAYCAR

Plastic bungs strip. They crossthread. They wear out after two seasons on the water. This one's all metal — square-cut threads that lock in positive, a 3mm nitrile rubber O-ring for a watertight seal, and a 2-year warranty to back it up. Fits a 25mm hole at 37 x 54mm with a 40mm mounting pitch. You'll need 2 x 4mm stainless countersunk screws; metal thread preferred, but woodscrews work if your transom's in sound condition
