Problems solved by technology

One disadvantageous characteristic of many pontoon boats is that the large deck structure, in combination with the pontoon and other framework of the pontoon boat, amplifies vibration and noise emanating from the outboard motor attached to a rearward part of the pontoon boat.

Embodiment Construction

[0033]Throughout the description of the preferred embodiment of the present invention, like components will be identified by like reference numerals.

[0034]Before describing various embodiments of the present invention, it is important to understand certain meanings of words and terminology that will be used in those descriptions and, just as importantly, it is important to understand certain types of support mounts that are not intended to be included within the scope of the preferred embodiment of the present invention. As an example, FIG. 1 shows an exemplary illustration of two plates, 10 and 12, attached together by fasteners, 14 and 16, with elastomeric material 18 therebetween. This type of connection shown in FIG. 1, with non-elastomeric components, such as the fasteners 14 and 16, directly connected between the two non-elastomeric plates, 10 and 12, is not the type of connection intended to be covered by the present invention. It does not provide sufficiently effective vibra...

Abstract

A marine propulsion support system incorporates a vibration isolation structure which comprises a plurality of elastomeric support components, or mounts. The vibration isolation structure is disposed between a marine vessel and a propulsion drive mounting transom to which a marine propulsion component, such as an outboard motor, can be attached. Support of the propulsion drive mounting transom by the marine vessel extends through the vibration isolation structure so that elastomeric portions of the elastomeric support components can damp any vibration emanating from a marine propulsion device, such as an outboard motor, and a deck of a pontoon boat or other marine vessel.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention is generally related to a vibration isolation system for marine vessels and, more particularly, to a vibration isolation system for use with pontoon boats having a marine propulsion device support pod attached below a deck of the pontoon boat.[0003]2. Description of the Related Art[0004]Many different designs are well known to those skilled in the art of pontoon boats. Typically, a marine propulsion device, such as an outboard motor, is attached to a support transom that is a portion of a pod, or scoop, that is attached below an undersurface of a deck of the pontoon boat. The outboard motor is generally mounted at a rearward location behind the deck and, in some cases, below the deck surface. The attachment is often to a transom portion of a pod that is suspended below the deck. This allows an outboard motor to be attached to the transom support plate in a manner that is generally similar to the wa...
