Scott Aerator Amherst 3 HP Fountain 230V 200 ft Cord – Lake & Pond Aerating Display Fountain System (SKU 13240-200)

The Scott Aerator Amherst Fountain (3 HP) delivers a breathtaking multi-tiered water display while significantly improving the oxygen levels and circulation of large ponds and lakes. Built in the USA with heavy-duty stainless steel components, this fountain offers exceptional reliability, year-round performance, and remarkable visual impact.

This is not a decorative pond accessory. This is infrastructure.

The Scott Aerator Amherst 3 HP Fountain is the commercial-grade floating fountain that HOA boards choose for retention ponds, golf course superintendents specify for feature lakes, and estate owners install when the centerpiece of their property needs to earn its place. At 3 horsepower, it moves 170 gallons of water per minute, projects a three-tiered cascading display to heights of approximately 35 feet, and spreads a curtain of aerated, oxygenated water 40 feet across the surface.

This 230V / 200-foot cord configuration is built for installations where the power source is set back from the water — no voltage drop compromises, no undersized cable workarounds. The extended cord ships pre-terminated with a 10-gauge submersible conductor engineered for the full 200-foot run at 14 amps continuous draw.

Built in Holland, Michigan and backed by Scott Aerator’s unconditional 5-year motor warranty, the Amherst is designed for exactly one operating mode: continuous, year-round, unattended duty in real-world pond and lake environments. It requires no oil changes, no seasonal removal, and no maintenance beyond occasional filter screen cleaning. The stainless steel motor housing, oil-free design, and saltwater approval make it as viable in a coastal brackish pond as in a freshwater HOA retention basin.

If you have a large pond, a commercial property, or a water feature that needs to make a statement and improve water quality simultaneously — this is your fountain.

Why Choose the Scott Aerator Amherst 3 HP Fountain?

• Three-tier display that scales with the water. The Amherst’s signature pattern — three distinctly separated tiers crowned by an impressive central column — is architecturally proportioned for large ponds. It looks commanding at quarter-acre and still holds the eye at five acres.
• 170 GPM of continuous surface circulation. Moving 170 gallons per minute across the surface disrupts the thermal stratification that starves deep water of oxygen, disperses algae-promoting nutrients before they concentrate, and keeps the pond biologically active at the surface where gas exchange happens.
• Built for 24/7/365 operation. The Amherst is engineered for continuous duty — not seasonal use. Its oil-free, water-cooled motor runs indefinitely without lubrication maintenance. In winter, leave it in the water and simply cut power when the pond freezes. Restore power in spring. No winterizing protocol, no damage from freezing temperatures.
• 200-foot cord — the right choice for real installations. Standard cord versions ship at 100 feet, which is undersized for most commercial pond setups where the power panel is set back from the water’s edge. The 200-foot 10-gauge configuration eliminates the need for field splices or secondary extension cable runs that compromise safety and motor longevity.
• American-made stainless steel construction. Every motor housing, filter screen, and float hardware component is stainless steel. The nozzle is precision-machined brass. Built in Holland, Michigan with domestic materials.
• Saltwater approved. The oil-free motor and full stainless construction make the Amherst suitable for brackish, coastal, and saltwater pond environments where conventional fountain motors corrode within months.
• Expandable with lights. Scott Aerator’s LED Night Glo and Color-Changing light kits screw directly onto the float — no rewiring required. For the 3 HP model, a 4-light kit is recommended for full pattern illumination. Lights can be added at purchase or any time after.

 Fountain Aeration - What the Amherst Actually Does To Your Water

The Amherst is classified as a display fountain with aeration benefits — not a dedicated aerator. Understanding this distinction is important for setting realistic expectations:

At 170 GPM, the Amherst moves a substantial volume of surface water and significantly increases oxygen exchange at the air-water interface. It disrupts surface stratification, reduces the stagnant conditions that favor algae blooms, and keeps the upper water column well-circulated. This produces measurable water quality improvements: reduced algae, better dissolved oxygen levels, and cleaner-looking water.

However, for ponds with severe oxygen depletion, heavy fish loads, significant muck accumulation, or deep-water stratification problems, a dedicated subsurface aerator (such as Scott Aerator’s own Boilermaker or DA-20 Display Aerator) moves dramatically more water per minute and addresses bottom-layer oxygen depletion more effectively. The Amherst excels as a combination display and surface-aeration solution. If aeration is the primary driver — not aesthetics — please call us to discuss the right product for your situation.

Installation Overview

Scott Aerator fountains are designed for straightforward self-installation once a power source is in place at the pond edge. Here’s what to expect:

• Power supply (the critical step): The 230V Amherst requires a dedicated 20-amp double-pole circuit breaker, GFCI protection, and an L6-20 plug. If you do not already have a 230V circuit run to the pond edge, a licensed electrician is required for this step. This is the only portion of the installation that requires a professional.
• Float assembly: The fountain ships with a float platform, motor, nozzle, and hardware. Assembly is straightforward following the included manual — no specialized tools required.
• Cord routing: Route the 200-foot 10-gauge cord from the pond edge to the power supply. Cord can run along the bottom or shore edge.
• Placement and anchoring: Float the assembled fountain in the desired location. Anchor with two mooring ropes attached to weights or concrete blocks at the pond edges. Scott recommends anchoring from two sides at approximately 90 degrees from each other. Anchoring weights and ropes are not included.
• Power-on and adjustment: Connect to power and observe the spray pattern. The Amherst nozzle delivers its classic three-tier pattern without adjustment. Optional: add Scott Aerator LED light kits (screw onto float, no rewiring required).
