Test Tank Guidlines - TOHATSU 40 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 will 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 tank which
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 from the engine
and work area.
• Water may splash out of the tank during testing. Maintain water
level (3) in the tank as illustrated.
• Keep transom board (4) at an approximate angle of 75˚ to the
tank bottom to ensure near vertical engine position.
