Overview

The Attwood Marine 911420 is a replacement transom shower hose for Attwood shower systems. It is sold as the HOSE-7' service part and is used with Attwood shower setups including the 4131 and 4133 systems.

This is the part you replace when the original shower hose has become stiff, cracked, kinked, or starts leaking, but the rest of the shower assembly is still worth keeping in service. On a boat with a built-in cockpit or transom rinse station, that kind of repair is often the quickest way to get the shower working normally again without changing the whole box, sprayer, and controls.

Key features

• Replacement hose for Attwood transom and aft-deck shower systems
• Listed as the HOSE-7' service part
• Fits Attwood shower systems including 4131 and 4133
• Made for freshwater shower setups used at the transom or under the gunwale
• Useful when the original hose is worn but the shower box, sprayer, and controls remain serviceable

Compatibility and fit

This hose is meant as a service replacement, not as a complete shower kit. It suits boats that already have an Attwood shower assembly installed and need the hose section replaced to restore normal pull-out reach and water delivery.

Before ordering, compare your current hose routing and attachment points with the existing shower assembly on board. This is a good match for owners servicing an Attwood rinse station used after swimming, boarding, or cleaning off salt and sand at the stern.

Installation and use

Replacement is most straightforward when the shower box and sprayer are already in place and only the hose needs attention. Route the new hose through the existing compartment with enough slack for smooth pull-out use, avoid tight bends that can pinch flow, and check the system under pressure before closing the access area back up.
