A jet ski not reaching its top speed can be due to various reasons, including debris intake, jet pump damage, supercharger failure, incorrect key or driving mode, presence of break-in mode, poor trim adjustment, inaccurate speedometer, deteriorated fuel or spark plugs, and a blown engine. These reasons apply mostly to 4-stroke jet skis, while 2-stroke ones might equally be affected minus supercharger problems, likely due to carburetor issues.

Cavitation, a common issue with jet skis and other watercraft, occurs when bubbles form in water under the vessel’s impeller, reducing its vapor pressure. Damages like a damaged impeller, wear ring, driveshaft, or intake-grate can cause cavitation. Usually, this is a result of suctioning up debris like rocks or sticks. Identifying and removing the debris, and repairing any damage, can resolve cavitation. Unfortunately, such repairs, often falling into the $100 to $1,000 range, are typically not covered under warranty as they’re usually caused by operator error, not manufacturing defects.
