Additional Information

OFS and OFS Pro Compatible — Universal Fitment:

Unlike some Reverso OFS accessories that are version-specific, the 35-3951-03 inlet hose kit is compatible with all Reverso Automatic OFS units including the OFS Pro. No version confirmation is required — this kit fits the full Reverso OFS product line.

What This Kit Does — Inlet Hose Function:

The inlet hose routes fresh water from the freshwater connection point (typically a deck-mounted quick-disconnect fitting) to the OFS system's water inlet port. The 3-foot length provides additional reach for installations where the OFS main unit is located below deck, in the bilge, or otherwise remote from the deck water connection. Without sufficient hose length between the deck fitting and the OFS inlet, the system cannot be properly plumbed — this kit resolves that installation geometry challenge.

Pre-Assembled Hose Section Only:

The 35-3951-03 is a pre-assembled hose section. It does not include the deck mounting housing or the quick-disconnect deck fitting. If you also need the deck-mounted quick-disconnect connection hardware, see the Reverso 35-3952-08 OFS Quick Disconnect Connection Kit.

3/4" Connections — Standard Sizing:

Both ends of the 35-3951-03 use standard 3/4" connections, consistent with the Reverso OFS system's water inlet port and standard deck quick-disconnect fittings. No adapters are required for standard OFS system installations.

Installation Notes:

• Confirm 3 ft. hose length is sufficient for your installation geometry before ordering — measure the routing distance between the deck fitting and OFS inlet port with the hose routed (not straight-line distance)
• Route the hose away from heat sources, sharp edges, and moving parts
• Avoid sharp bends in the hose that could restrict flow or cause premature wear
• Refer to Reverso OFS installation documentation for the correct inlet hose connection procedure for your specific OFS version

Frequently Asked Questions

1. Is this inlet hose kit compatible with the OFS Pro?
Yes — the 35-3951-03 is compatible with all Reverso Automatic OFS units including the OFS Pro. Unlike the OFS remote switch (35-3954-02), which is OFS Version 3.0 only, this inlet hose kit fits the full Reverso OFS product line.

2. Does this kit include the deck quick-disconnect fitting?
No — the 35-3951-03 is a pre-assembled inlet hose section only. The deck-mounted quick-disconnect fitting is a separate part. See the Reverso 35-3952-08 OFS Quick Disconnect Connection Kit if you also need the deck fitting.

3. How do I know if 3 feet is long enough for my installation?
Measure the routed distance — not straight-line distance — between your deck quick-disconnect fitting and the OFS system water inlet port, accounting for bends and routing around obstacles. If 3 feet is insufficient, contact Reverso or us at MacombMarineParts.com to confirm if a longer inlet hose option is available.

4. What size are the hose connections?
Standard 3/4" connections at both ends, consistent with the Reverso OFS system inlet port and standard deck quick-disconnect fittings. No adapters required for standard OFS installations.

5. Can I use this kit on a new OFS installation or is it only for existing systems?
Both — the 35-3951-03 can be used in a new OFS installation where the inlet hose is needed to bridge the distance between the deck fitting and the OFS unit, or as a replacement hose on an existing installation where the original hose is damaged or insufficient length.
