A support system is provided for an outboard motor which uses four connectors attached to a support structure and to an engine system for isolating vibration from being transmitted to the marine vessel to which the outboard is attached. Each connector comprises an elastomeric portion for the purpose of isolating the vibration. Furthermore, the four connectors are disposed in a common plane which is generally perpendicular to a central axis of a driveshaft of the outboard motor. Although precise perpendicularity with the driveshaft axis is not required, it has been determined that if the plane extending through the connectors is within forty-five degrees of perpendicularity with the driveshaft axis, improved vibration isolation can be achieved. A support structure, or support saddle, completely surrounds the engine system in the plane of the connectors. All of the support of the outboard motor is provided by the connectors within the plane, with no additional support provided at a lower position on the outboard motor driveshaft housing.

Structural support system for an outboard motor

A support apparatus for a marine propulsion system in a marine vessel is provided with a compliant member that is attachable to the transom of a marine vessel. In certain applications, the compliant member is directly attached to an intermediate plate and to an external frame member that is, in turn, attached directly to the transom of the marine vessel. The intermediate plate is attached directly to components of the marine propulsion system to provide support for the marine propulsion system relative to the transom, but while maintaining non-contact association between the marine propulsion system and the transom.
