Small Bolt-in Mounting Cone
When the propulsor is installed using the small mounting
cone there is no need to compromise hull strength
around the propulsors, as the needed openings in the
hull can be kept to a minimum. Mounting cone installation
allows the propulsor to be installed in one piece
from below or in two pieces, upper gearbox from above
and lower gearbox from below.
