Does anyone know the Seadoo 717/720 Engine PTO Spec's? The 717/720 is (82mm x 68mm) 718.5cc. It use's a Threaded PTO. The 650/657 (78mm x 68mm) 650.1cc use's the same Crank. The 650/657 use's the same Head Bolt pattern as a 580, 582, 583/582UL, 617/618UL, 670. The 717/720 use's a bigger bolt pattern, but could be made to fit by oblonging the holes.
