Up for sale is my 1998 Seadoo challenger. It has twin 720cc rotax motors. Both motors have 150psi compression in both cylinders. So compression is perfect, healthy motors with low hours. Boat was last out 10-01-2018 The boat ran great with no issues it would go up to 50mph with a breeze. Everything is functional on the boat, radio works, gauges work, Everett, Washington »
