What if a rope goes into the jet pump?

Short answer

The commonest drive damage on a jet ski comes from ingestion. In none of the wordings reviewed do the words impeller or jet pump even appear.

A mooring line, a drifting net, a plastic bag, sand in the shallows: a jet drive sucks in, and what it sucks in goes through the impeller. The damage runs from a bent blade to a destroyed pump unit with knock-on damage to the shaft. For jet ski owners this is the standard loss, not the exception.

In insurance terms it is an orphan. In none of the thirteen wordings reviewed do the words impeller, jet pump or drive unit appear at all. Machinery damage without external influence is excluded almost everywhere, and whether an ingested rope amounts to external influence is precisely the point that then gets argued. In practice that means this loss is effectively uninsured across the market.

What you can do here is worth more than any clause. Keep clearance from the bottom in shallow water, watch for fishing gear and buoy lines, and lift the impeller for a look after any ingestion before you carry on. And if damage does occur, photograph the foreign object before you remove it. That is the evidence of external influence the argument will later turn on.

Is that machinery damage or an accident?

That is exactly the question. Documenting the foreign object argues for external influence, and therefore for an accident.

Does machinery cover help?

It is the right place for drive damage, but everywhere it carries age limits and its own exclusions. Check there whether ingestion of foreign objects is carved out.
