NOTICE
Indmar does not recommend applying fogging oil while
the engine is running. The fogging oil could damage the
catalytic converter. The cylinders must be protected by
removing the spark plugs and applying the fogging oil
directly into the cylinders.
3. After all the cylinders have been treated, crank the
engine to spread the lubricant on the cylinder walls.
Replace the spark plugs in the engine.
4. Perform annual maintenance; refer to Section 7,
Scheduled Maintenance Chart.
Seawater Cooling System Preparation
Your Indmar engine is equipped with a cooling system
that uses a 50/50 propylene glycol antifreeze and water
mixture in the engine block and raw water in the heat
exchanger and exhaust system. If the boat is kept in
an area where the temperature falls below the freezing
point of water (32°F or 0°C), the cooling system must be
winterized to prevent freeze damage to the engine.
The protection level of the antifreeze must be tested
using an antifreeze tester that is designed to test
propylene glycol antifreeze. These testers are available
at automobile parts stores and can also be found on
many websites that sell automotive related tools and
equipment. Follow the instructions that come with the
tester and make sure the antifreeze in the engine will
protect to lower than the lowest temperature that your
part of the world experiences.
