I have a 1981 E33 and have a problem with the setup for the 2 forward cockpit drains. It is laid out with 2 drains t connected to a forespar seacock and plastic thruhull, the t connector seacock and thru hull are all below water line in a small box molded in hull just forward of the rudder. The thru hull is mounted horizontally and is very close to the bottom of hull. The seacock that was on ther was a 2 piece design and was able to screw onto thru hull without a problem. When the handle on forespar seacock broke my troubles started. I purchased a new 1 piece seacock and since the thruhull so close to bottom of hull there is not enough clearance to screw it on. I temporarily fixed it with a plastic 2 piece coupler but am not happy with the layout. The 2 aft cockpit drains connect each to their own above waterline thruhulls on stern. I am thinking about connecting the forward drains to the aft drains with a y connector and get rid of below waterline thru hull. I am looking for flaws in my idea, wondering why it wasnt originally designed like my idea. Has any other E33 owners run into this problem, and what was done to correct it?
