Boat Engine and Outdrive Flush System Marine Tech has developed a line of Quick Flush ValveTM hardware for easy flushing, maintenance and winterizing of your boat engines and motors; gas, inboard/outboard, outdrives, diesel, genset, ACs. The Quick Flush ValveTM bronze fittings mount permanently in your engines cooling system for easy connection to garden hose flushing, anti-freeze winterizing and emergency bilge pumping.
Quick Flush Valve Systems are sized for the ID of the cooling water intake hose.
"Just want to say 'thanks'. Bought one of your bronze flush valves, works great. Told everyone on my dock about it." - Bill, Avid Boater
"Bought one of those plastic flush valves from the competitor, it cracked from the vibration! We didn't lose the boat but I'm launching this year with the bronze fittings in the Quick Flush Valve System." - Wayne, Knowledgeable Boater
NOTE: Quick Flush ValveTM Systems are constructed with rugged and durable bronze fittings that will last for years, unlike others that use fatigue-prone plastics.
Whether you trailer or dock, follow your prescribed engine maintenance, and keep your motors sweet and clean with regular flushing.
INSTALLATION NOTE: Quick Flush ValveTM Systems are sized to fit the Cooling Hose Inner Diameter (ID) of the Engine water supply. Components (valves and tees) of the Quick Flush ValveTM Systems are sized for proper cooling water flow and are not the same as the hose ID.
