SEAFLO 33 Series Washdown Deck Kit
The SEAFLO 33 Series Washdown Deck Kit delivers 3.0 GPM at 70 PSI, suitable for thorough deck cleaning on boats and RVs. This model is self-priming up to 6 feet, which helps when the water source is not directly above the pump. The unit uses EPDM valves and a Santoprene diaphragm for durability in fresh and saltwater applications. The built-in heavy-duty pressure switch activates the spray nozzle when the trigger is squeezed and shuts off when released, reducing pump wear and providing precise control. This kit is designed for quick, reliable cleaning tasks on marine vessels and recreational vehicles alike.
Key features include a robust 12V DC power supply, 1/2″-14 MNPT inlet/outlet connections, and a high-efficiency performance profile that keeps cleaning time short even in harsher marine environments. The component selection prioritizes reliability and ease of maintenance, making it a practical option for boat decks where space and weight are considerations.
SEAFLO 55-Series Washdown Kit
The SEAFLO 55-Series kit features a 12V DC diaphragm pump delivering 5.5 GPM at 60 PSI. It is designed for heavy-duty cleaning tasks across boats, RVs, decks, and outdoor equipment. The included hose, high-pressure spray nozzle, quick-connect fittings, and inline filter create a ready-to-use system that streamlines installation. The pump is self-priming with an adjustable pressure switch, enabling flexible operation for various cleaning needs, from light rinsing to deep scrubbing. This all-in-one solution is especially suitable for users seeking a balanced combination of power and simplicity for regular maintenance.
With robust mounting and corrosion-resistant components, this kit addresses marine exposure while maintaining consistent water flow and pressure. The adjustable switch helps tailor performance to different spray patterns for efficient deck washing, sterns, and rails. The value lies in the convenience of a complete package designed for straightforward hookup and dependable operation at sea or on the road.
80 PSI 7.5 GPM Washdown Deck Kit
This kit provides high-performance cleaning with up to 7.5 GPM and 80 PSI, suitable for heavy-duty deck and exterior washes on boats and RVs. Its five-chamber diaphragm design supports strong, steady flow while the self-priming feature accommodates vertical lift up to about 6 feet. A built-in pressure switch starts and stops the pump automatically as the spray nozzle engages, helping to manage water use and protect components. The kit’s design emphasizes durability for marine environments, including corrosion-resistant body construction and vibration-reducing features for smoother operation on waves or rough surfaces.
Boat Juice Boat Wash & Shine
Boat Juice Boat Wash & Shine combines a pH-neutral formula with a 2-in-1 wash and wax approach. The product is formulated to remove grime, salt, scum, and stains while leaving a gloss finish without stripping wax. The included Hydrosuds Sprayer Attachment offers a rich foam application with eight spray patterns, and the Dual-Action Wash Mitt provides soft chenille for gentle scrubbing and a waffle weave for tougher grime. This option emphasizes preserving hull and deck finish while delivering straightforward cleaning for marine surfaces in USA-made packaging.
7.5 GPM 80 PSI Washdown Kit
This kit delivers up to 7.5 gallons per minute at 80 PSI, targeted at RVs, boats, yachts, and travel trailers. It features a quiet operation profile with low power consumption and a closed-motor design that resists corrosion. The thermal overload protection safeguards the system during sustained use, and the included strainer and pressure switch support dependable performance in saltwater and humid environments. The system is positioned for those needing robust cleaning power without excessive noise or energy draw.
Buying Guide
- Flow rate vs. pressure needs: Higher GPM helps with fast deck rinsing; higher PSI handles stubborn grime and salt. Balance both based on deck size and typical cleaning tasks.
- Self-priming ability: Essential when the water source is not directly above the pump; look for lifts around 6 feet or more for flexibility.
- Durability in marine environments: Seek pumps with corrosion-resistant housings and EPDM/Santoprene components for freshwater and saltwater use.
- Included accessories: Kits with hoses, nozzles, filters, and fittings reduce setup time and simplify installation.
- Noise and power considerations: Look for motors with vibration dampening and energy-efficient performance to minimize disruption during use.
- Maintenance: Inline filters and accessible diaphragms simplify routine checks and prolong pump life.
- Compatibility: Ensure inlet/outlet sizes match existing hoses and fittings; standard 1/2″-14 MNPT is common for many marine systems.
