Yea you have to cut into that, it is where your floatation foam is, then dig some of it out (I dug a hole down to the bottom and hook my drain hose for the tray to the hose that runs on the bottom of the boat under the foam)I also have a 93 PII. then fiberglass it all in. If I had to do it again I would just slant the foam to the front of the boat and drill a hole through the front of the box then fiberglass it in and let the water drain from the tray into the front of the boat. either way works.Last edited by Bassdeer on December 23rd, 2013, 1:35 pm, edited 1 time in total.
