That is a sail drive. Volvo, Yanmar and several others make them. It has a
number of advantages and a few disadvantages. A SD is quieter than a shaft
drive. Less drag. Cost less as a package installed, does not have as much
turning torque in reverse. The bad part is you have to haul every six
months to change the shaft zinc.
You would come out a lot cheaper just replacing the unit with another
saildrive. Closing up the hole and iInstalling a standard shaft at this
point will take longer and cost more.
