Bilge Siphon Feature
The Jet Drive incorporates an automatic bilge siphoning feature. The bilge siphon is working
whenever the engine is running above idle speeds. Maximum performance of the bilge
siphon is realized above 3,000 RPM. A hose is attached to the jet pump nozzle. The hose
is routed to the engine compartment and placed in the bilge. Water exiting the nozzle creates
a suction or vacuum in the hose creating the bilge siphon, drawing water out of the boat.
Installing Bilge Siphon
The siphon break must be located above the water line at the highest point. The siphon
break has a 0.020 in. hole which must be kept open.
1. Uncoil the siphon hose. Place the pick up screen in the bilge.
2. Place the siphon break (located in the siphon hose) above the water line at the highest
point. Fasten hose with cable tie so that the siphon break will stay at the highest point.
