I have a Super Maramu from 1995 OO30017SM141. The mainsail furling gearbox apparently failed and needs replacement. The desision to remove the unit was made by my maintenance guy since I am on the west coast and the boat is on the east coast. I ordered a new one and when it arrived it was not from Bonfiglioli and was not interchangeable. I haven't been able to find one that could be delivered by 20 June which is when I need to have it. Does anyone have a serviceable gearbox they want to sell or know where I could get one deliverd to Florida by 20 June?
