Personal Watercraft (PWC)
50-hour Service

Average labor time: 2hrs

Inspection and servicing of all components are vital to the operation of your personal watercraft every 50 hours of riding time. Services include:

  • Oil change
  • Replace oil filter
  • Inspect/replace spark plugs (as needed)
  • Grease power take-off (as needed)
  • Lube and inspect throttle body

Hydrolock Removal

Average labor time: 3hrs minimum

Hydrostatic, hydraulic, or hydro lock occurs when water enters an engine cylinder. For example, flipping or sinking a PWC and then trying to start the engine will bring water up the exhaust system, filling the crankcase with water. Because water does not compress, the engine becomes locked up.

Hydrolock is a serious situation that requires immediate action to prevent irreparable damage to the engine. Our experienced mechanics will remove the water, flush the crankcase and inspect the machine for further damage.


Average labor time: 1hr

In cold climates, it is crucial to winterize your personal watercraft. Our skilled mechanics will remove water from the cylinder block and exhaust system to prevent freezing. Also, fogging the cylinders with oil prevents corrosion and rust, and disabling the electrical system will prevent the engine from being started until ready to de-winterize.


Average labor time: 1hr

Dewinterization is the process of enabling the electrical system, charging the battery, running an engine compression test, and test-firing to ensure dependability all season long.


Average labor time: 1hr
