I have a 2006 Hunter 45cc which has a SL spirit atlantic windlass. I need to replace the bearings as they have rusted out. I am having trouble removing the motor gearbox from the holding plate on the deck. The gypsy is off, the split ring that held the bearings are off. There are no ball bearings left. I of course removed the 4 nuts under the deck holding the assembly together. I can get the unit to drop about 2 inches but will not clear any further to remove completely. Is there something I am missing. I have the parts diagram and can not see anything that should prohibit it from being removed
