SUMMARY
Using a boat's propeller to excavate sand is feasible, particularly when employing a tube to direct thrust downward. While some dredges utilize separate propellers, it is possible to use the boat's propulsion system for limited sand removal, specifically 1-2 feet of silt directly beneath the vessel. However, significant power is required for larger volumes of sand, and care must be taken to avoid clogging the engine's cooling water intake with sand and water mixtures. Additionally, considerations regarding propeller erosion due to sand exposure are crucial.
