His dad bought the boat from the front yard of a house at Mannering Park NSW in 67
Was in a poor state had a Dodge Q direct drive
Converted it to a ski boat runabout and glassed the hull
Added an extra plank both sides for more freeboard
Changed name to JOY-O
sold in late 70's
Mid 80's seen with Y block installed
I know its relatively unlikely anyone has info on this boat but it amazes me how much 'stuff' these forum members have collectively in the grey matter
