9. PRIME AND DISCHARGE

Prime and discharge

・

While the engine is running with the cowl

removed, do not touch the rotating parts of the

pulley or belt.
This may cause personal injuries.

・

If, when operating the vacuum pump for 30

seconds, the pump does not suck water or if water

drop out of the pump during the water discharge

operation, check the following:

・

Is the tip of the suction hose completely below the

water surface?

・

Is air sucked through the joint of the suction hose?

・

Is the suction hose damaged?

・

Does the vacuum performance of the priming pump reduced

significantly?

・

Does

the pump case leak vacuum?

・

Does a vacuum leak occur when the pump is connected with the

suction hose of which the opening is capped?

Refer to “Chapter 16 TROUBLESHOOTING”.

After the engine starts, pull the priming lever.

Check that the pumped water is discharged

continuously from the priming outlet of the

vacuum pump.
Be sure the pressure gauge shows positive side.
