Gas Model Features

• Fits most gas engines rated from 25 hp to 2000 hp. Twin gas models available.
  
  
• Microprocessor based electronics with 2-stage adjustable calibration of GPH & gallons used for superior accuracy.
  
  
• Simultaneous independent display of Engine Hour Time, RPM, GPH, gallons consumed, and nautical MPG.  Twin gas model displays the MPG rate for BOTH engines underway.
   
• RPM readout accurate to 10 RPM. Easily connects to existing tach signal wires.
   
• GPH and Totalizer readings displayed in tenths of a gallon.  Totalizer capacity up to 99,999 gallons.
  
  
• Dual color (amber/green) backlighting of LCD provides for easy night viewing.
  
  
• Requires 1 Momentary ON / Constant OFF toggle button switch for resetting fuel totalizer reading.  See Accessories page for recommended push button switch (4001-433-00) for this feature.
  
  
• Single and twin engine models require 1 SPST toggle switch for accessing MPG reading.  See Accessories page for recommended toggle switch (4001-434-00) for this feature.
  
  
• Twin gas models also incorporate an Engine Synchronizer Indicator and Port/Stbd GPH selection.  2 additional SPST toggle switches are required for accessing these features.  See Accessories page for recommended toggle switch (4001-434-00) for these features.
  
  
• Meter fits 3-3/8" panel opening (standard tach size).  Can replace existing tachs in panel.
  
  
• Models available in black or white (bezel/dial face).
  
  
• Uses Model 20A, 2OB, 231, and 233 Series flow sensors designed for gas engines.
  
  
  

  Applications
  Fits all carbureted inboard and stern drive engines up to 350 hp.

  Fits all EFI inboard and stern drive engines (including Mercruiser and Volvo) with closed loop fuel return systems.

  Fits all Mercury Optimax, Evinrude Ficht, Yamaha HPDI, and Honda 4-stroke engines.

  Fits all 2-stroke EFI outboard engines.
  
  
  Important note for the following outboard engine owners:
  - Evinrude E-Tec 2-cycle
  - Mercury Verado 4-cycle 
  - Suzuki 4-cycle 
  - Yamaha 4-cycle

  The engines listed above have two fuel pumps. Because the engine's lift, or low pressure pump cycles on and off while filling the vapor separation module, the FloScan instrument GPH/LPH readings will constantly fluctuate between 0 GPH/LPH and approximately 25-50 GPH or 95-190 LPH depending on lift pump and engine size. Though the GPH/LPH readings are unusable, the FloScan instrument will accurately record total fuel consumption as displayed in the totalizer window.
