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.
Features
- GPH models available with 0-16, 0-24, 0-32, 0-50, and 0-100 GPH
scales. Color styles include black dial/bezel, white dial/bezel, and white
dial/chrome bezel. Requires 1 Momentary ON / Constant OFF
toggle button switch for resetting fuel totalizer reading.
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.
- Dial faces: Black on White, or White/Red on Black. U.S &
Metric Scales.

Please confirm whether your outboard engine listed above has one or two fuel pumps (low
and high pressure pump). Earlier versions of these engines typically have a
single fuel pump where a FloScan system can be used.
Newer model
engines with two fuel pumps (low and high pressure) may cause the FloScan
instrument's GPH or LPH readings to fluctuate between 0 GPH/LPH and
approximately 25-50 GPH or 95-190 LPH depending on the lift pump and engine
size. This is due to the engine's lift, or low pressure pump, cycling on and
off while filling the vapor separation module. Though the GPH/LPH readings may
not be usable under this condition, the FloScan instrument will accurately
record total fuel consumption as displayed in the totalizer
window.
