The air conditioning water discharge should flow upward and exit through a thru-hull fitting located above the waterline to allow for visual inspection. The thru-hull should be mounted within 18 inches of the waterline to minimize water splashing noise. Use a reinforced marine-grade 5/8”inch hose for the discharge line, ensuring there are no high spots or loops to prevent air locks and maintain efficient water flow. All air conditioning water lines should be double hose clamped with the clamps reversed. Proper 316 stainless steel marine-grade hose clamps must be used.
