•  Know  the  waters  and  area  you  will  be  boating;  tides,  currents,  sand  bars,  rocks,  and  other 

hazards.

• Check steering for free operation.

• Check for debris around the rudder and reverse gate which may jam or hinder operation.

•  Before  launching,  examine  the  jet  drive  water  intake  for  obstructions  which  may  prevent 

pumping of water.

• Ensure the driveshaft bearing on the jet drive is lubricated.

Operating In Salt Water Or Polluted Water

If the boat is kept moored in the water, always tilt the outboard so the water intake is completely 

out of water when not in use.

Wash down the outboard exterior and flush out the exhaust outlet of the jet drive with fresh water 

after each use.

When  used  in  salt  water  more  than  in  fresh  water,  remove  mounting  hardware,  grease,  and 

reassemble once a year. Failure to do this may result in hardware that is difficult if not impossible 

to remove at a later date.

Operating In Shallow Water

The life of the impeller and water intake can be greatly increased by avoiding the intake of sand 

and gravel. The intake suction will act like a dredge when the water intake comes close to the 

bottom. It is better to stop the engine and drift up to shore when landing, and to shove off with 

an oar when leaving. The engine can idle through areas of water less than 61 cm (2 ft.) deep, but 

there should be more than 61 cm (2 ft.) of water under the boat when increasing speed to reach 

full plane.

Once the boat is on plane, the boat speed will prevent the ingestion of gravel and other debris 

from the bottom. The suction is still present, but the water intake passes too quickly over the 

bottom to allow debris to be drawn into the water intake.

When boating through shallow water areas, choose a course of travel that avoids sharp rocks and 

other underwater obstacles that could damage the boat. Running the boat through these areas on 

full plane may be helpful as the boat will be riding higher in the water. If the boat gets stuck on 

the bottom, immediately stop the engine and move the boat to deeper water.
