How is seaweed or other debris cleared from the jet intake?
There are several methods with the first being to Backflush the jets. Backflushing is running the jet backwards for a short period by engaging transmission reverse. This pumps water out of the intake to blow off debris caught on the intake grill. Rare blockages that are not removed by backflushing can be cleared from inside the boat via the access cover. Other options are available for mission-specific applications. 11. Can the jets handle sand and gravel? Yes, the occasional gulp of sand or gravel is not detrimental to the jet drive. In fact, waterjets are much less susceptible to damage than an underwater propeller in similar conditions. Continuous operation in sandy or silted water will accelerate wear of the impeller. Remember to keep the power low when crossing sandy shoals so that there is reduced tendency to draw sand or gravel into the jet. 12. What if the boat runs aground? Some jet boats have a small keel or skeg but otherwise most jet boats have no underwater appendages. The
