Ocean 54 Winch Gearbox

Adam Body

I need to replace the original port-side jib sheet winch gear box: it is a Bonfiglioli VF 63, MVF63/P unit. Can anyone suggest a replacement which will fit the existing electric motor which seems very sound.  I am located in Australia at Greenwell Point on the NSW south coast.  Flora was originally Amelie IV which some of you may remember..
