Sequencer Retrofit Kit

Sizes: Twin, Triple, and Quad Engine (Quad up to 350 HP)

Flushing sequencers use a series of electric gates to direct fresh water through each engine, one at a time. But like all plastic, mechanical, and electrical devices exposed to the harsh marine elements, they eventually succumb to the wear and tear of boat life. When it’s time to replace yours, the Sequencer Retrofit Kit integrates into your existing flushing plumbing and swaps the sequencer for the PHIBER PHLOW Hub. Its oversized apertures and inner partitioning chamber protect water flow and pressure, flushing up to four engines at the same time with simple physics. Easy to install, zero maintenance.

Features

  • Marine grade construction (no “planned obsolescence”)
  • Elegant design with minimal installation footprint and complexity
  • Requires only “Physics” to operate: no electronics, electrical, or mechanical functions
  • Engineered for maximum water flow and minimum pressure loss
  • Replaces the valve sequencer between the dock hose connection and the engine freshwater flush plumbing

Kit Includes

  • PHLOW Hub
  • 1 1/4″ x 1″ reducer bushing for connecting to smaller network plumbing (dock hose)
  • PHIBER PHLOW Hub Overlay
  • Flush Placard
  • 3/4″ MPT Plug (Twin Engine kits)

Phlushing Convenience

Solo Freshwater Maintenance System

For smaller boats that can’t support a push-button PHIBER System but still need a routine freshwater flush for their engine, bait well, or other application at the end of the day. The Solo Kit allows for freshwater maintenance of a single application, with hose connection at a location that’s convenient to reach, eliminating hard-to-reach flush ports and the often-risky gymnastics of flushing an outboard if the vessel is stored on a lift or stays in the water. Oversized fittings deliver full flow to the engine during the flush.

Features

  • Marine grade construction (no “planned obsolescence”)
  • Minimal installation footprint and complexity
  • Allows flushing for single or twin engine configurations (additional fittings sold separately)
  • Compatible with other PHIBER Overboard Manifolds
  • Puts the freshwater flush hose connection in a convenient location

Kit Includes

  • Flush Placard
  • Perko Dock Hose Inlet
  • NPT-to-Barb fittings (stainless)

Phlushing with PHLOW

Multi Freshwater Maintenance System

Choose your size and finish at checkout.

Sizes: Twin, Triple, and Quad Circuit (Quad up to 350 HP)

Elegant and simple in both form and function, this Freshwater Maintenance System lets the full freshwater flow from a single dockside hose flush multiple engines at the same time. That means less water waste, less time and labor, and no more hooking a garden hose to each engine’s flush port. Its key feature is the patent-pending PHIBER PHLOW Hub, machined with oversized apertures and a unique partitioning chamber so flushing water divides smoothly and evenly, keeping GPM and pressure equal to every engine for a superior flush. It’s so effective it can often replace a less efficient valve-sequencing flush control, at a reduced cost!

Features

  • Requires only “Physics” to operate: no electronics, electrical, or mechanical functions (no “planned obsolescence”)
  • Elegant design with minimal installation footprint and complexity
  • Engineered for maximum water flow and minimum pressure loss
  • Eliminates the need for a complex valve sequencer
  • Single hose connection flushes up to four engines using direct “Hub-to-Head” plumbing through the engine’s rigging bundle

Kit Includes

  • PHLOW Hub (clear anodized)
  • 1 1/4″ x 1″ reducer bushing
  • PHIBER PHLOW Hub Overlay
  • Flush Placard
  • 3/4″ MPT Plug (Twin Engine kits)
  • Perko Dock Hose Inlet
  • NPT-to-Barb fittings (stainless)
