Shoreline Marine Bilge Pump Plumbing Kit
The Shoreline Marine kit is a straightforward option for small to mid-sized boats. It ships with a plastic bilge pump hose, a thru-hull fitting, and two stainless-steel hose clamps, offering a compact, easy-to-install setup. Best for owners who want a quick, no-fuss installation with essential components included in one package. Consider this kit if your bilge system requires a simple, compatible 3/4″ x 5 ft hose and you value fast installation over advanced customization.
Pros: simple components, affordable, fast install. Cons: lacks extra hose length choices and may suit smaller bilge applications better than high-capacity systems. Caution: verify hose length and fitting compatibility with your pump’s outlet to avoid leaks.
12V Automatic Boat Bilge Pump Kit, 1100GPH
This Subtoy kit is ideal for boats needing automatic operation. It features a built-in float switch for auto on/off, powered by 12V, and a teardown-ready submersible design. Choose this if you want hands-off water removal and reliable performance in both saltwater and freshwater. The kit is best for fishing boats, runabouts, and small yachts where unattended maintenance is a priority due to its automatic control feature.
Limitation: ensure your electrical system can support the pump’s 1100GPH capacity and that mounting locations accommodate the float switch’s auto-activation.
Bilge Pump Installation Kit with 1-1/8″ Hose
The MAXZONE installation kit targets mid-to-large bilge systems with a 1-1/8″ outlet. It includes 6 ft of kink-free hose, two stainless clamps, and a thru-hull connector. It stands out for adjustable length and a cuff-less inner bore to minimize leaks. Best for buyers needing a flexible, longer hose run and a sturdy connection. Use this when you want a reliable, scalable setup for larger bilge volumes.
Limitation: the 6 ft length may require additional hose for larger bilges; plan routing accordingly.
1100 GPH Automatic Bilge Pump Kit (1-1/8″)
This FILTERUP kit blends automatic operation with broad marine applicability. The 1100 GPH pump handles significant water flow and includes six feet of 1-1/8″ hose, two clamps, and a thru-hull fitting. It’s a solid choice for boats that require robust, automatic removal of bilge water without manual intervention. Suitable for larger boats, cruisers, and yachts that demand reliable, continuous water management.
Caution: automatic pumps depend on accurate sensor functioning and proper installation; ensure the hose routing avoids kinks and blockages that could impair performance.

The hose design emphasizes smooth inner flow and anti-leak construction, making it a solid choice for DIY installations on boats needing dependable hose integrity. Best for owners who want a compact, reliable hose-and-fitting package with straightforward setup.
Limitation: ensure compatibility with your bilge pump’s outlet size and overall system layout to prevent mismatches in hose diameter or fittings.
maierke 1-1/8 Inch Hose Kit
The maierke kit provides a complete 6 ft 1-1/8″ kink-free hose, one ABS thru-hull fitting, and two stainless clamps. It emphasizes a smooth inner bore and anti-kink construction, which helps maintain steady flow and reduce leaks at connection points. Best for buyers who want a durable, easy-to-cut hose with reliable clamps for boating environments of varying sizes.
Limitation: verify that the included fittings match your specific pump model and vessel plumbing layout to avoid size or thread mismatches.
Buying Guide: Key Purchase Considerations
- Hose size and compatibility: Most kits use 1-1/8″ or 3/4″ hoses. Match the hose diameter to your bilge pump outlet for a secure seal and optimal flow.
- Through-hull fittings: Ensure fittings are compatible with your hull material and mounting location. ABS fittings are common and generally durable for marine use.
- Automatic vs. manual operation: Auto pumps with built-in float switches simplify unattended operation but require reliable sensor placement. Manual kits give you full control but require you to trigger operation.
- Hose length and routing: Consider the total hose run when selecting a kit. Longer runs increase the risk of kinks; kink-free hoses help maintain steady drainage.
- Clamps and hardware: Stainless steel clamps resist corrosion but verify their size fits your hose diameter to ensure a tight seal.
- Material durability: Look for corrosion-resistant materials for fittings and hoses, especially in saltwater environments.
- Installation complexity: Some kits are ready-to-install, while others require cutting hoses or drilling through-hull fittings. Choose based on your DIY comfort level.
