Maintaining a water-jet propulsion unit is crucial for the efficiency and longevity of marine vessels.

Here’s a general maintenance guide:

Regular Inspections:

• Visual checks: Look for any signs of damage, wear, or corrosion on the unit, nozzle, and surrounding components.

• Intake grate: Regularly inspect and clean the intake grate to prevent debris from entering and damaging the system.

• Seals and bearings: Check seals and bearings for leaks, wear, or damage.

• Nozzle and steering mechanism: Ensure proper functionality, inspect for any signs of wear, and lubricate moving parts as needed.

Cleaning:

• Flushing: After each use, flush the unit with clean water to remove any salt, sand, or debris that could cause damage.

• De-scaling: Periodically clean the unit to remove scale buildup using manufacturer-recommended descaling agents.

Lubrication:

• Greasing: Lubricate moving parts and bearings regularly using appropriate marine-grade lubricants.

• Seal maintenance: Ensure seals are in good condition and replace them if necessary to prevent water leakage.
