Modern Jetskis get up to high speeds and because of this its not difficult to cause hull damage. This Yamaha Waverunner had some deep hull damage that required rebuilding with glass and epoxy in two areas near the keel line. Because of the high speeds from these craft, the water pressure can delaminate the hull skin further while underway. Being black careful prep and blending was required for a seamless repair. Placing the ski on work stands makes for easier access to carry out repairs.
