The Jabsco Q401J-115S-3A Par-Max HD4 is a heavy-duty 12V DC marine freshwater delivery pump designed for reliable high-pressure water delivery in boats. It features a 4 GPM open flow rate, cast aluminum lower housing, and an integrated bypass for smooth, on-demand operation with dry-run protection. Best suited for marine vessels with 2-4 water outlets requiring high-pressure freshwater delivery in rough conditions.
The Little Giant APCP-1700 is a 1/3 HP automatic submersible pump designed to remove standing water from pool covers, boat covers, and flat roofs. It features a mechanical float switch that activates at 2 inches of water and deactivates at 1.5 inches, offering a high flow rate of up to 1745 GPH at low head pressure. While effective for its intended purpose, it is not suitable for continuous duty or dirty water applications.

Professional reviewers and editors highlight the Little Giant APCP-1700 as an industry-leading solution for preventing pool cover damage due to its high flow rate and automatic operation. They praise its energy-efficient motor, quick activation, and robust construction, noting it is ideal for all types of pool covers. However, in-depth expert tests are scarce, with descriptions focusing primarily on specifications rather than hands-on verdicts.
Consumer feedback is sparse but generally positive regarding ease of use and effectiveness. Users commonly praise the pump's portability and ability to remove water quickly. The most recurring complaint is the tendency for the pump to air lock, which stops operation and requires manual fixes, such as using two hoses to prevent air intake.
Professional sources emphasize the pump's durability, high performance, and marine-grade build quality, noting that the HD series offers improved pressure and lifespan through its cast aluminum housing and heavy-duty motor compared to standard plastic models.
