Kestrel Take
The muscle-car of skis — a supercharged 300hp Rotax in an aggressive hull built to carve. Thrilling and hard-used by nature. The supercharger service, wear ring, and hard-riding damage are the whole inspection. A supercharged ski with no service history is a real gamble.
Known Issues for the 2020 Sea-Doo RXP-X 300
