the middle of the belt to check the tension.

The give in the V-belt should measure about

8∼10mm at the depression.

The mixing elbows which are constantly in contact with exhaust gas and seawater deteriorate with

use and must be replaced. If operation is continued without replacing faulty elbows, water will leak

into the boat, and gas leakage may result in fires.

If the V-belt tension is too tight, the belt

and the bearings of the alternator will be

damaged.

Be careful not to spill any oil on the V-

belt as this will lead to stretching and

slippage.
