ANyone know the dimensions/diameter of the outlet fitting on the side of the boat for the AC discharge? I push pink backwards through the system with a drill pump, but i'd like to get some hose this year that properly fits the discharge so i'm not spraying everywhere trying to get it flush
 
I found that the smallest diameter tube that came with the drill pump worked the best

On the 300 the actual inner diameter of that port was a lot smaller than it looked

Also -- simply stuffing something around the tube (like a paper towel) goes a long way!
 
Yup - or just wrap what you have with tape till it fits just right.
 
For anyone interested, a 1/2” plastic hose barb fit perfect and snug. Not a drip while I pumped pink through with a submersible pump
