2.91:1 Belt reduction drive available. It was used with Rotax 447 and 62" Powerfin Prop combination on a Kasperwing. Works great, but we have upgraded our redrive systems. Clean and in great shape. Includes PTO and Prop pulleys, shaft assembly, pillow blocks and brand new belt. Just posted to Barnstormer's as well. $495.00 plus shipping costs. Feel free to contact me if questions.
