Damper plate type is chosen according to vessel use, and actual selection is based on transmission splines, flywheel diameter and engine torque
Linear Damper Plate - designed for general applications, provides a linear dampening of the torque applied to the system
Hammer Head - designed for general use where motoring at low RPMs is common, provides a two stage dampening of the torque with 10 degree deflection of the element
High Deflection - designed for use in vessels where low RPM engine use is the norm as in work boats or where gear noise is being experienced; gives three distinct stages of dampening with 33 degree deflection of the element
