Final answer:
When re-boarding a Personal Watercraft, roll it over in the direction indicated by the manufacturer's decal to avoid engine damage. This is to ensure water does not enter the engine compartment, which can be costly and dangerous.
Step-by-step explanation:
To re-board a Personal Watercraft (PWC), such as a jet ski, after falling off, you should roll it over in the direction indicated by the manufacturer's decal. Most PWCs will have a decal on the rear of the craft indicating the correct direction to roll it in order to avoid damaging the engine. It's very important to follow these instructions because rolling the PWC the wrong way may cause water to enter the engine compartment, resulting in engine damage. The reason manufacturers specify a direction is because of the way the engine and machinery are configured within the PWC.
The process of re-boarding usually involves swimming to the stern of the PWC, locating the decal for roll direction, then using the grab handle to pull yourself onto the craft. Ensuring that you re-board in a safe and controlled manner can help protect both you and the PWC from harm, allowing you to continue enjoying your time on the water.
