The Gilmour 474S salt water nozzle is perfect for your bow washdown hose
The hose nozzle up on the bow has a tough duty; the salt water causes corrosion on the both the outside finish and the internal mechanical components. Then the nozzle quits working after about a year when the internal spring gives way to rust.
The Gilmour 474S "salt water nozzle" is designed by the manufacturer for this harsh duty. A durable polymer body with stainless internal spring.
This is a good news / bad news post; bad news is Gilmour is discontinuing the product, good news is they are on clearance at Amazon.com for less than $6 with shipping.
