I have a 72 Trojan that has a factory head with water line and mace
pump. The original configuration had the waste water dumping to the
water thru a valve. At some point the previous owner instead rerouted
the waste AFTER the pump to 2 5 gal bucket holding tanks that must be
manually emptied.

Is there a holding tank (small one) I can replace this with so I can
pump out, or

is there some way to put a pump out on these buckets

or can I simply put it back the way it was and have the waste go right
in the water ?

Seems to me that if the boat was built that way it is ok or Not ?

TIA
