Seawater Inlet Hose

• A reinforced hose capable of supporting 10 in. Hg vacuum must be used to prevent the
seawater inlet hose from collapsing from pump suction.
• The hose should be oil and seawater resistant.
• Use the shortest hose length possible with the least number of bends to minimize
restriction.
• All connections must be secured with a hose clamp.
• Fasten hose as appropriate to maintain proper routing and to prevent chafing or contact
with other moving parts.
