Have a plugged drain in my boat.

[arbogaster]

Working on something beneath the floor in the cuddy of my boat and noticed the drain from the bulkhead in the cutty to the rear of the boat drained rather slow. I attempted to push the blockage through using a metal rod and now it is totally plugged. I am wondering what to do now since any water that fins its way into this compartment will be trapped unless I clear the blockage. My two options at the moment are

1. 120 PSI from the air compressor and try to blow it out

2. Long flexible drill bit from LOWES and work it down the hole slowly

Thoughts?

I would try water hose first and than maybe air but turn the pressure down a bit, 120 psi can do some damage to stuff.. I wouldn't be running a drill bit threw it at all

I've also cleaned them with a good shop vac
