Test Tank Guidelines - TOHATSU NB-1000 Service Manual

TEST TANK GUIDELINES

When properly setup, test tanks provide a safe and controlled environment
in which to perform outboard engine adjustment and testing procedures.
Test tanks must be setup to the minimum dimensions shown. If multiple
engines wiII be installed in the tank, secure partition plate (1) so that the
minimum dimensions are maintained for each outboard engine installed.
In addition, adhere to the following guidelines to prevent engine damage:
• Continuous usage raises the water temperature in the tankwhich
can lead to engine seizure. Make sure water temperature in the
tank does not exceed 77°F [25°C].
• Repeated use introduces carbon into the water which can adhere
to the engine cooling system and degrade its ability to cool the
engine. Always replace dirty tank water at regular intervals with
clean, fresh water.
• Exhaust gases produced during engine operation can collect
around the engine, causing suction into the carburetors and
affecting engine performance. To prevent this condition, install
forced ventilation equipment (2) to remove gases away from the
engine and work area.
• Water may splash out of the tank during testing. Maintain water
leveI (3) in the tank as illustrated.
• Keep transom board (4) at an approximately 75° angle to the
tank bottom to ensure near vertical engine position.
