The Spectra Ventura 150R is the most popular DC-powered marine watermaker in Spectra Watermakers' Marine Ventura Series, producing 6.3 gallons per hour (24 liters per hour) of clean, drinkable fresh water from a compact, modular reverse-osmosis system. The Ventura 150R runs directly off a 12V or 24V house battery bank, drawing power from solar, wind, or the bank itself — making it the watermaker of choice for cruising sailboats, sportfishing yachts, catamarans, and liveaboards from 30 to 50 feet.
SeaLife Marine, an authorized Spectra Watermakers dealer based in Bradenton, FL, sells, installs, and services the Ventura 150R and the full Ventura Series across Tampa Bay, the Sun Coast, and the Florida west coast.
The Ventura 150R uses Spectra's signature Clark Pump energy-recovery architecture, which recycles brine-line pressure to amplify feed pressure to the reverse osmosis membrane. The result: a fraction of the power demand of legacy high-pressure marine watermakers at the same output. The 150R draws so little current that it can run for hours off a moderately-sized solar array (typically 400W+) without depleting the house bank.
For cruisers, that means fresh water on the hook, off solar, or under sail — without firing up the generator or running the engine. For liveaboards and off-grid cruisers in the Bahamas, the Caribbean, or the Sea of Cortez, it means indefinite water independence at remote anchorages.
The modular design lets the boost pump, Clark Pump assembly, and membrane housing mount independently in lockers, lazarettes, or under bunks — ideal for retrofits where engine-room space is at a premium. Commercial-grade diaphragm pumps replace the high-RPM piston pumps of legacy systems, making the 150R quiet enough to run overnight without disturbing the v-berth.
SeaLife Marine sells, installs, and services every model in the Spectra Marine Ventura Series.
6.3 GPH. 12/24V DC. 60 lbs. The most efficient compact watermaker in the series. Spectra Remote Manual control panel. Best for 30–45 ft cruisers running on solar and a 12V house bank.
6+ GPH. 12/24V DC. 85 lbs. Same output as the 150R, with full Spectra Connect integration — touchscreen MFD display, advanced modes, and full remote operation.
6+ GPH. 12/24V DC. 60 lbs. The most economical, mechanic-friendly watermaker in the 150 line. Simple analog controls — feed-pressure gauge and product flow meter. No electronics to troubleshoot.
8+ GPH. 12/24V DC. 85 lbs. Spectra Connect MFD, remote operation, advanced modes. Sized for warm water above 50°F — the right pick for larger crews and tropical cruising grounds.
8+ GPH. 12/24V DC. 85 lbs. Tropical-spec membrane in a modular, remote-controlled package. Same energy efficiency as the 150R, scaled up for bigger tanks and bigger crews.
8+ GPH. 12/24V DC. 60 lbs. Tropical conditions with simple analog controls. Compact, modular, reliable — the no-electronics, no-fuss option for warm-water cruising.
Most modular installs are completed in 1–2 days, depending on access to the chosen mounting locations and how the through-hulls are configured. SeaLife Marine provides a detailed boat survey before scheduling.
Yes. The 150R's low DC draw makes it one of the most solar-friendly marine watermakers on the market. A 400W+ solar array is generally sufficient to make several hours of water per day in good conditions while still topping the bank.
Routine maintenance includes prefilter swaps on a regular interval, freshwater flush after each use, and pickling for long lay-ups (Z±ION compatible). RO membrane life is typically 5+ years with proper care. SeaLife Marine provides a full maintenance schedule with every install.
The Ventura 150R can run dockside for testing, but watermakers should not be used in marina water for production due to chlorine and contamination. Run it on clean offshore water for production, and flush with dock water through a carbon filter.
Yes. SeaLife Marine is an authorized Spectra Watermakers dealer and carries out warranty diagnostics, parts replacement, and Spectra-approved service in-house at the Bradenton, FL facility.
Tampa Bay and the Sun Coast are SeaLife Marine's home waters, but the team services the broader Florida west coast on demand and offers yacht-delivery support along the Gulf and Atlantic coasts.
