Series 5500, Gasoline Only
A Series 5500 CruiseMaster Fuel Monitoring System will increase
any boat's effective range by accurately recording total fuel
consumed by pinpointing optimum speed. Now you can spend more
time fishing or cruising knowing you have enough fuel to make it to
port. CruiseMaster brings you more than peace of mind and
increased cruising range, it also pays for itself in better fuel
economy. Fits virtually all inboard, I/O, and gas outboard engines.
5500
Features
  • Self contained Totalizer with permanent LCD display records fuel
    consumed up to 99,999 gallons. Resettable or non-resettable totalizer
    operating mode.  SPST type switch required for resetting totalizer.
  • Model 20B Flow Sensor with solid state signal generator for
    maintenance free use. Installs between tank and fuel pump.
  • Model 231 Flow Sensor features extremely low flow resistance.
    Recommended for outboard engines 150 HP and over where system
    flow resistance should be minimized. Installs between priming bulb and
    fuel tank.
  • Microprocessor-based electronics with user adjustable totalizer
    calibration for superior accuracy.  Panel mounted instrument fits 3-1/16"
    diameter opening.
  • Models available with 0-5, 0-10, 0-20, 0-32, 0-50, and 0-100 GPH
    scales.  HP rating will determine the best GPH scale to use.
  • Twin engine models show the individual flow rates to each engine with
    an external switch (not supplied), and the Totalizer records the
    combined fuel consumption of both engines.

Applications:
  • Fits Mercruiser and Volvo EFI engines.
  • Fits all Mercury Optimax and Evinrude Ficht engines.  Fits all EFI
    outboard engines.
  • Fits all carbureted gas inboard, outboard, and stern drive engines.
  • For gas EFI engines with fuel return lines that are directly connected to
    fuel tank such as Crusader and Marine Power EFI engines, contact
    FloScan system.

7700
Multifunction Meter combines a digital LCD Engine Hour
Meter, Tachometer, Fuel Flowmeter, and Fuel Totalizer in a
single 3-3/8" diameter instrument which fits the panel space
of a standard tach.  A popular option is to replace the existing
tach(s) with this system thus eliminating the need to cut new
holes in the panel.
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, and gallons
    consumed.
  • 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.
  • Single engine models require 1 external SPST (on/off) panel switch for resetting fuel
    totalizer reading.
  • Twin gas models also incorporate an Engine Synchronizer Indicator and Port/Stbd GPH
    selection.  2 additional SPST panel switches are required for accessing 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.

Series 9000/9500/9600 Multifunction
Meter with NMEA 0183 Serial Receiver
for Nautical MPG over ground
For Gasoline Engines
GPS Interface System combines a digital LCD Engine Hour Meter,
Tachometer, Fuel Flowmeter, Fuel Totalizer and  nautical Miles Per Gallon
over the ground in a single 3-3/8" diameter instrument which fits the panel
space of a standard tachometer.  The speed signal required to calculate
the nMPG reading is obtained from GPS and Loran systems having a
NMEA 0183 serial port output. The direct display of nautical Miles Per
Gallon over the ground gives the skipper a powerful new tool to set
optimum fuel efficiency under all conditions and to determine precisely how
far he can go with his remaining fuel.

TwinScan™ Engine Instruments
Outstanding Readability in Half the Space
TwinScan™ Instruments embody a new concept in twin engine analog instrumentation which
sets the ultimate standard for easy readability in the least possible space. Each individual
instrument contains port and starboard meters which reference to each other. TwinScan
instruments reduce the panel space required by 50% leaving more room for other electronics.
TwinScan Fuel Flowmeters and Tachometers are sold separately.

Deluxe Features:
  • Tachometer /  MPG / Synch Indicator uses an NMEA 0183 speed signal from a GPS or
    Loran, and a fuel flow signal from a TwinScan™ GPH instrument to digitally display  Fuel
    Efficiency (NM/Gal)  or the RPM difference between port and starboard engines.
  • Microprocessor electronics for high performance features like electronic dampening,
    linear dial scales, superior accuracy unaffected by ground voltage shifts.
  • Patented, magnetically shielded, precision, miniature air-core meter movement with state-
    of-the-art engineering features.
  • Corrosion free stainless steel bezel (black, white or polished) and molded acetal cases
    which fit standard 3-3/8" diameter holes.
  • Reverse polarity and load dump protection exceeding SAE J1810 standards.
