The Reverso #35-3955-01-01 is the engine setup fittings kit required for the Reverso OFS Pro Automatic Outboard Flushing System — single-engine configuration.

This fitting kit is required for OFS Pro installation and is not included with the OFS Pro unit (35-3957-01-04) — it must be ordered separately.

⚠️ Kit Contents Note: Specific fitting contents (sizes, straight vs. elbow configurations) for the 35-3955-01-01 are not confirmed in current product data. Contact us at MacombMarineParts.com or Reverso directly with your OFS Pro model to confirm the exact fittings included before ordering.

Additional Information

Required Fitting Kit for OFS Pro — Not Optional:

The Reverso OFS Pro unit (35-3957-01-04) requires the 35-3955-01-01 fitting kit to connect to the engine's built-in cooling flush ports. Without this fitting kit, the OFS Pro cannot be plumbed to the engine. The fitting kit is sold separately from the main OFS Pro unit — if you are purchasing the 35-3957-01-04 OFS Pro complete accessories kit, add the 35-3955-01-01 to your order at the same time. Contact us at MacombMarineParts.com to confirm and bundle both items.

OFS Pro Flushing System — Not an Oil Change System:

The Reverso OFS Pro is an automatic outboard engine cooling water flushing system — it flushes salt, sand, and debris from the engine's raw water cooling system with fresh water after each use. It is not an oil change or fluid transfer system. Reverso also manufactures separate oil change pump systems; the OFS Pro and the oil change pump are distinct product lines. The 35-3955-01-01 is the engine fittings kit for the OFS Pro flushing system only.

Single-Engine vs. 2-Engine Fittings Kit:

The 35-3955-01-01 is for single-engine OFS Pro installations. For twin-outboard OFS Pro setups, see the Reverso 35-3955-01-02 OFS Pro 2-Engine Setup Fittings Kit. Order the correct kit for your engine count — these kits are not interchangeable.

Requires Built-In Engine Flushing Ports:

The OFS Pro system (and therefore this fitting kit) is designed for outboard engines equipped with built-in flushing ports. Confirm your outboard has built-in flush ports before purchasing. Most modern four-stroke outboards include them; confirm with your engine documentation or dealer.

Outlet Fitting Size — 300HP+ Guidance:

Based on the standard OFS fittings kit (35-3955-02) design pattern, larger outlet fittings (1/2") are recommended for engines 300HP or more to avoid restricting cooling water flow. Confirm the correct outlet fitting size for your specific engine against Reverso's OFS Pro installation documentation.

Installation Notes:

• Order alongside the OFS Pro unit (35-3957-01-04) — the fitting kit is required and not included with the main unit
• Confirm kit contents with Reverso or us before installation
• Confirm your outboard has built-in flushing ports before ordering
• Refer to Reverso OFS Pro installation documentation for engine connection procedure

Frequently Asked Questions

1. Is this fitting kit included with the Reverso OFS Pro unit (35-3957-01-04)?
No — the 35-3955-01-01 is sold separately. The OFS Pro unit (35-3957-01-04) explicitly requires this fitting kit but does not include it. Add both to your order when purchasing the OFS Pro system. Contact us at MacombMarineParts.com to confirm and bundle.

2. What is the difference between this kit (35-3955-01-01) and the 35-3955-01-02?
The 35-3955-01-01 is for single-engine OFS Pro installations. The 35-3955-01-02 is for twin-engine OFS Pro setups. Order the kit that matches your engine count — they are not interchangeable.
