Pump Operation

1. Important: Fill crankcase with oil (There is no oil in the crankcase when you receive the pump).

Approx. 22 ounces / 0.65 liters (Figure 1)

• Summer: use SAE 30 Oil.

o

• Winter (under 40

F or 4oC): use SAE 5W-20 Oil.

2. Fill gas tank. Briggs & Stratton recommends using a lead-free gasoline (minimum of 85 octane). Allow

1/4" or 5 mm of tank space for fuel expansion (Figure 1).

3. To Start Engine

A. Open fuel valve. Turn fuel shut off valve to "ON" position. It is located underneath the gas tank.
B. Move choke to "CLOSE" position. The choke lever is white in color and located below the carbu­retor (Figure 1) Move the lever to the left.

C. Move throttle to "FAST" position. The throttle is located (Figure 1) above the choke lever and has a red
cover on it. Move the lever to the full left position.

D. Grasp rope handle (Figure 1) and pull slowly until resistance is felt. Then pull cord rapidly to overcome
compression, prevent kickback and start engine. Repeat if necessary with choke open.

E. When engine starts, move choke to mid position and then, to full right "OPEN" position when

warm.

NOTE: Minor adjustments to the carburetor and governor may be necessary to get pump running to
specs. Please refer to Briggs & Stratton engine Owner's Manual which was enclosed with this document.

4. Place pump in water and start for fastest prime.

A. Pump may fail to prime properly if started in fast idle position on shore first. For one person opera­tion, start on shore at a low idle and then place it in the water.

5. To Stop Engine
A. Move throttle control to full right "Stop" position. Do not use Choke control to stop engine.

Operating Notes:

• Do not submerse the muffler in water. May cause damage to the engine.

• Use a 2.5" dia. discharge hose. BP3 pumps are low pressure/high volume. Any

thing less than 2.5" dia. will restrict flow and reduce GPM output.

• When using on grass remove the intake screen to prevent clogging.

SALT WATER MAINTENANCE

Otterbine floating pumps may be used in salt water applications providing the pump is immediately flushed
with fresh water after use for 7-10 minutes at full throttle. The exterior hardware must be rinsed and wiped
dry. Note, salt water is very corrosive, pump parts will wear faster under these conditions.

STORAGE INSTRUCTIONS

If the Otterbine pump is to be stored for 30+days, do the following:

1. To prevent dirt or gum deposits in the fuel system, drain engine of fuel. Run the engine until it stops
from lack of fuel.

2. Float assembly should be removed for easier maintenence. To remove the float assembly, disengage the
hold-down straps (see parts breakdown pg. 8-11). Lift engine/pump assembly up and away from the
floats.

3. While engine is still warm, drain oil from crankcase. Refill with oil.

4. Remove spark plug. Pour approximately .5 ounce/15ml of engine oil into cylinder and crank slowly to
distribute oil. Replace spark plug.

5. Clean dirt and chaff from cylinder, blower housing, rotating screen, and muffler area.

6. Store the pump in a clean and dry area.
