Why Your Jet Ski Is Not Reaching Top Speed [11 Reasons]
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.
