Ran a shop bench full of "dead" jetskis this season and it's almost always the same 4 things:

1. Spark plugs — salt + heat cycles eat electrodes way faster than the manual says. If you're past 100 hours and haven't swapped, you're gambling.

2. Fuel filters — clogged filters mimic a dying engine. Half the "my jetski won't rev past idle" calls I get are a $12 filter, not a $1,200 problem.

3. Drive belts — dry rot from UV + trailer storage. Inspect for hairline cracks before every season, not just when it snaps mid-ride.

4. Impellers — sand/gravel intake nicks the blades, kills your top-end speed before you even notice a full failure.

Most riders carry zero spares and end up stranded on the trailer waiting on a part that should've shipped same-week.

That's the whole reason Warpski exists — we stock the wear parts that actually fail, not just OEM catalogs nobody can find in stock. If you ride jetski or jetboat and want fast-shipping spares/accessories instead of waiting on a dealer backorder, come take a look.

Drop your model below and I'll tell you exactly which of these 4 to keep on hand.
