No, not if the Jetslide system is properly used. The Jetslide has a V-shaped entrance point, specially designed to block the engine stand when the boat gets to final resting position. If you follow the instructions and use the product correctly, the engine will not damage the Jetslide. If you do not follow the recommendations or do not use the system properly, then the Jetslide can be damaged. The Jetslide has been foamed to prevent sinking in case of an accident.
