Hey MJ another Seo Ox owner needs help
 

this guy is posting over on Iboats....any idea how your boat is plumbed?

ok, I recently purchased my 1988 sea ox 230c with omc sea drive. trying to get some kinks worked out and ran into a confusing problem. while fishing today i filled my fishbox with ice. problem : the water wont drain. i figured it was probably just clogged like every other drain in the boat. but my method of forcing water through it has not worked. now im trying to figure out how the box is plumbed and which hole on the side of the boat water is supposed to come out of, or where else it coudl come out of. if anyone is familiar with this boat and how it might be plumbed, any help would be appreciated

I have the same issue only on the left side, I have stuck wire, water and still no drains out. will after a month maybe?

It drains into the bilge, you get in there from the last deck plate, there is a hole there wear it comes out. Min e was hard to find, so I filled the right side and saw were it came out, then found the other side.

There is really no way to re-plum it unless you cut into the stringers or floor that I know of.
I have not put 100% effort into clearing the drain so if you find a better way let me know!

Thanks MJ, I passed it along.
