Features of VF53AS

1.Light weight and compact
Engine and pump castings are made of anti corrosive aluminum-alloy to reduce weight and prolong
working life.

2.Maximum reliability
VF53AS is powered by TOHATSU's original developed 4stroke 3cylinder engine which has achieved
lower emission and maximum fuel economy for environment protection. The technology which has
proved itself in TOHATSU's state-of-the-art outboard engines ensures maximum reliability for any fire
fighting scenes in all seasonal condition.

3.Quick priming
Quick priming is provided by simple operating Rotary Vane Vacuum Pump. The pump primes 3meters
in only 3seconds.

4.Low emission
CO emission is lowered by 43%*. HC and NOx lowered by 90%*.

5.Low noise and less vibration
Low noise (Reduced by 9dB*) and less vibration does not interfere with speech communication during

*Numerical data are comparison with our two stroke models operating at 0.4MPa.

6.Excellent fuel economy
Electrically controlled fuel injection helps optimum fuel supply depending on engine speed,
maximizing lower fuel consumption.

7.Engine overheat protection sensor
Engine overheat protection device is provided to safeguard against cooling water loss, and to protect
engine in the operation with discharge valve closed. This device automatically shuts off engine when
engine temperature reaches 80℃.

8.Electrically controlled fuel injection
Electrically controlled fuel injection secures reliable engine starting under any weather condition even
in the event of low battery power.

9.Auto priming system
Rotary vane vacuum pump is automatically activated after engine starts, and cut off once priming is completed.

10.Double swivel outlets rotating with in a 90 degree.

1. Battery charger
2. Tool kit

Optional accessories
1.Floodlight projector
2.External fuel tank (stainless, 20liters)

Some different type of adapters for suction inlet and discharge outlet are available.
