Flow-Rite V3 3-Position Automatic Livewell Valve Rear Cable

Set It and Fish. The V3 Handles the Rest.

The Flow-Rite V3 is a 3-position automatic livewell valve built for anglers who want hands-free livewell management. A single standard aerator pump mounts directly to the valve body, handling both filling and recirculation automatically no second pump, no constant adjustments, no guesswork.

Designed with a rear cable approach, the V3 is the ideal choice for bass boats, flats boats, and other low-profile fishing vessels where clean, low-maintenance livewell systems are a must.

How It Works

• AUTO: The go-to mode for active fishing. When the boat is off plane, the valve recirculates and aerates livewell water while blending in a continuous supply of fresh water. Spent water exits through the overflow, preventing ammonia buildup and keeping your catch healthy. When the boat gets on plane, the built-in check flapper closes automatically to prevent water loss and replenishes when you slow back down. All of this happens without any input from you.
• RECIRC: Closes off outside water completely. Use this when adding ice or livewell treatments, passing through locks, traveling to a weigh-in, dockside refueling, or any time you don’t want fresh water mixing in.
• EMPTY: Turn off the pump and move to EMPTY for fast gravity draining no tools, no mess.

Best For

Bass boats, flats boats, and low-profile fishing vessels where automatic livewell management is a priority. If your boat has a front cable layout, see the Flow-Rite V3 Front Cable version. For a manually controlled 3-position valve, explore the Flow-Rite V4 Select Valve. For a simple 2-position shutoff, check out the Flow-Rite V1 Shut-Off Valve.

Parts Desk Insights

The V3 is the best recommendation for customers who want a fully automatic livewell system with minimal operator involvement particularly bass boat and flats boat owners. It’s a strong upgrade over basic shutoff valves and a popular replacement part. If the customer’s cable exits from the front of the console, direct them to the V3 Front Cable version instead. Customers asking about adding a pump-out or venturi aerator should know the RECIRC mode supports that optional addition.
