Reverso OFS Inlet Hose Kit | 35-3951-04 | 6-Foot Freshwater Extension | All OFS & OFS-Pro Units

The Reverso #35-3951-04 is a 6-foot pre-assembled inlet hose kit that extends the freshwater connection point on a Reverso Automatic Outboard Flushing System from the OFS unit to a more accessible location — a deck fitting, transom connection, or any convenient hookup point within 6 feet of the unit. It connects to the OFS unit's standard 3/4-inch water inlet port and is compatible with all Reverso Automatic OFS units including OFS-Pro versions. If your installation requires more reach, also see the Reverso OFS 9-Foot Inlet Hose Kit (35-3951-05).

Additional Information

6-Foot vs. 9-Foot Inlet Hose — Choosing the Right Length:

Reverso offers inlet hose kits in both 6-foot (35-3951-04) and 9-foot (35-3951-05) lengths. Before ordering, measure the routing distance from your OFS unit's inlet port to your intended freshwater hookup point — deck fitting, transom connection, or hose access point — and add slack for routing bends and a clean installation. Key considerations:

• 6-foot kit (this part) — suitable for installations where the OFS unit is relatively close to the desired hookup point; typically engine compartment units with a nearby deck fitting or transom connection
• 9-foot kit (35-3951-05) — suitable for longer runs; bilge-mounted units, units in forward rigging compartments, or installations where the hookup point is further from the unit
• When in doubt, choose the longer kit — excess hose can be routed and secured with clamps; a hose that is 6 inches too short cannot be extended without additional fittings

Both kits connect to the OFS unit's standard 3/4-inch water inlet port and are compatible with all Reverso Automatic OFS and OFS-Pro units.

Frequently Asked Questions

1. How do I decide between the 6-foot and 9-foot inlet hose kit?
Measure the routing distance from your OFS unit's water inlet port to your intended freshwater hookup point — deck fitting, transom, or hose end — and account for bends and routing slack. If the distance is clearly under 5 feet, the 6-foot kit (this part) is sufficient. If you are unsure or the distance is close to 6 feet, choose the 9-foot kit (35-3951-05) — extra hose length can always be managed with routing clamps, but a hose that falls short forces additional fittings and a less clean installation.

2. Is this hose kit compatible with my Reverso OFS-Pro unit?
Yes — the 35-3951-04 is compatible with all Reverso Automatic OFS units including OFS-Pro versions. Unlike some Reverso accessories that are version-specific (such as the remote switch 35-3954-06 which is OFS Version 3.0 only), the inlet hose kits work across the full Reverso OFS line.

3. What connection does the far end of the hose use?
The hose uses a standard 3/4-inch connection. The unit-side end connects directly to the OFS unit's water inlet port. The supply-side end connects to your freshwater source — a deck fitting, transom fitting, or garden hose. Verify that your chosen termination point uses a compatible 3/4-inch connection before ordering.

4. Is this the complete flushing system or just the hose extension?
This is the inlet hose extension kit only — it is an accessory for an existing or new Reverso Automatic OFS installation, not a standalone flushing system. The OFS main unit, engine setup fittings, and any other installation hardware are separate components.
