Before Starting


Your WATERMASTER Floating, Self Priming Pump is shipped dry. Oil must be added to the pump’s transmission and the engine crankcase.

Add 1.1 L or (40 oz.) of oil to the transmission. Use hydraulic oil or 30 mineral oil. In colder weather a lighter oil should be used in the transmission.

Refer to the Engine Operator’s Manual for engine oil and fuel recommendations. Do not spill gas on the pump. If you do, wipe it up.

For easier starting we suggest that you start the pump on shore and let it run till it warms up. After it has warmed up, shut the engine off, float the pump on the water then restart the engine.
