E-Z Oil Drain Kit - Fits Oil Pan Drain Plug Holes With Metric 12 X 1.75 Thread (Most Late Model MerCruiser Pans)

This kit is the answer to the job we all hate - oil changes. By installing an E-Z oil drain hose into your existing drain plug hole you simply pull the other end out the drain plug hole and drain the oil from outside your boat. It doesn't get any easier than this!

The hose is 44" long and has a cap. The end of the hose is approx 13/16 and passes through all standard 1/2"NPT drain plug outlets. These drains kits use 3/8" marine hose. NOTE: To pull drain hose through the external drain plug requires a minimum 7/8" hole.

Gen 4 BBC oil pans are typically 1/2"-20 and Gen 5/6 pans are typically 12mm metric.
