Do not run pump dry for more than 30 seconds. Lack of

water flow may damage impeller. To drain pump, loosen

end cover screws.

SERVICE INSTRUCTIONS

IMPELLER REPLACEMENT: Remove end cover and

gasket. Pull impeller out by grasping hub or blades with

pliers. Replace impeller, gasket and end cover. A light

coating of grease in impeller bore will aid priming on dry

start up. (Use correct Jabsco gasket, a thicker or thinner

gasket may cause impeller damage.) Standard gasket is

0.010" thick.

INSTALLATION INSTRUCTIONS

Engage shaft with drive tang, make sure flange seats

squarely on mounting surface and bolt to engine.

Connect inlet and outlet fittings using pipe compound to

seal threads.
