Livewell Pump Guide: Hooker Livewell System Explained

A properly set-up livewell system can be the difference between healthy bait and a long day of frustration. Boats such as the Twin Vee 340 GFX or the 400 GFX2, equipped with the Hooker sea chest livewell system, are designed to deliver consistent water flow and pressure, but proper operation matters.

In the YouTube video linked above, Captain Skip walks through the correct way to run the Hooker livewell system on a Twin Vee, using the 340 GFX as an example. The same principles apply across Twin Vee models equipped with this system.

In this edition of Mastering Your Twin Vee, we'll explain how the system works, which controls matter most, and the most common mistakes owners make.

Understanding the Hooker Sea Chest System

The Hooker system uses a centralized sea chest that feeds water to the livewells through dedicated pumps. Water enters the system through a through-hull intake, fills the sea chest, and then flows to each livewell depending on which pump and valve are open.

On the 340 GFX, the system uses two 2500-gallon-per-hour pumps. These pumps supply water to the livewells and allow the operator to adjust flow depending on bait type and conditions.

Even though there are two pumps, they are not designed to run at the same time. While it may seem like two pumps would offer more power, running them together can create a vacuum lock in the sea chest or cause pump motor failure. This mistake is where the majority of livewell problems occur. Avoid damaging your system and downtime from fishing by using only one sea chest pump at a time.

One pump provides more than enough flow to fill and pressurize two livewells simultaneously when set correctly.

Identifying the Key Components

Before operating the system, it helps to understand what you are looking at.

The through-hull intake supplies raw water to the sea chest. From there, water moves through two separate pump circuits labeled livewell one and livewell two.

Each pump has:

• A dedicated switch at the helm
• A flow control meter at the helm that adjusts how much water moves into the livewells
• A corresponding ball valve in the bilge

The ball valves control whether water can flow through each pump circuit. Their position matters as much as the pump switch itself.

3 Steps to Proper Operation

• Select Your Pump: Turn on only one livewell switch at the helm (Livewell 1 or Livewell 2).
  
• Align the Valves: In the bilge, ensure the ball valve for your active pump is Open (parallel to the pipe) and the idle pump is Closed (perpendicular).
  
• Dial Your Flow: Use the helm flow meters to adjust pressure. A setting of 50% to 75% is ideal for standard circulation; 100% is used only when high-pressure saturation is required.

Common Mistakes to Avoid

Most Hooker livewell issues come down to a few avoidable errors:

• Running both pumps at the same time
• Forgetting to open the correct ball valve
• Leaving the wrong valve open when switching pumps
• Assuming more pumps means better flow

Success on the water is all about the details. The Hooker livewell system on a Twin Vee is designed for reliability and flexibility. When used correctly, it delivers consistent flow, strong pressurization, and excellent bait health.

Twin Vee PowerCats Co. Establishes Autonomous Marine Steering Committee to Advance AI-Enabled Maritime Vessels 
Amid Growing Defense Demand

On Tuesday, Twin Vee announced the formation of a Strategic Steering Committee dedicated to advancing autonomous marine technology. This initiative aims to position the Company as a solution provider for the U.S. Navy’s evolving drone strategy and broader commercial applications. The committee, which includes the Company's directors and executive management, will focus on addressing technical gaps recently exposed in unmanned maritime systems, such as software instability and operational failures.

Leveraging its vertically integrated manufacturing facility in Fort Pierce, including a 46-foot, five-axis CNC router, Twin Vee is in a position to, if requested, help accomplish the U.S. Navy's current drone strategy, subject to further exploration of procurement opportunities and formal government dialogue. By controlling the process from tooling to propulsion integration, the Company believes it can provide the structural precision required for reliable AI and sensing systems.

The Committee’s roadmap includes identifying AI partners and creating a scalable framework for autonomous safety. While the initiative is currently exploratory, it signals a potential pivot toward defense-sector procurement and high-tech marine innovation.
