Here is exactly what you will find "In the Box" for the Rule 7700D GPH Evacuator Pump:

Included Components

Rule 7700D Evacuator Pump: The main 12V submersible unit (usually finished in Rule's signature red and white).
Integrated Strainer Base: A high-flow, snap-on plastic strainer already attached to the bottom to prevent debris from clogging the impeller.
Heavy-Duty 12V DC Wiring Leads: Two leads (positive and negative) of heavy-gauge wire, pre-attached to the motor.
Instruction Manual & Warranty Information: Essential for proper wiring and fuse installation.

What You’ll Need (Sold Separately)

Because the 7700D pulls a massive amount of power (up to 100 Amps), you will almost certainly need additional components to make it functional:

100 Amp Fuse and Holder: Rule strictly requires a 100A fuse to protect the motor and your power source.
High-Current Power Supply: This pump requires a heavy-duty battery or 12V power supply capable of sustaining high amperage.
3" (76mm) ID Hose: The discharge port is large—you’ll need a 3-inch hose and high-quality stainless steel hose clamps.
Heavy-Gauge Extension Wire: If your battery is more than a few feet away, you'll need significant gauge wire (e.g., 0/2 AWG or similar) to prevent voltage drop.

Quick Setup Note

Because this pump moves 7700 GPH, it generates significant torque and discharge pressure. Make sure the 3" hose is securely clamped and the pump is placed on a stable surface before powering it up, or it can "walk" or kick when it starts.

Ideal For:

✔ Large boats & yachts
✔ Commercial fishing vessels
✔ Workboats
✔ Emergency response & marine service crews
✔ Dock & marina maintenance

Why Choose the Rule 7700D Pump?

Rule Pumps are known worldwide for durability and performance. The 7700D Evacuator Pump is built for serious water movement where smaller bilge pumps won’t suffice. Whether you're preparing for offshore conditions or need reliable emergency backup pumping power, this model provides peace of mind and professional-grade output.

Important Installation Note

This pump is designed for high-capacity water transfer applications. Proper wiring, circuit protection, and hose sizing are critical for optimal performance. Always follow manufacturer installation guidelines.
