Mounting assembly and lock ring for marine stern drive engine
First Claim
1. A mounting assembly for an outboard marine engine, the mounting assembly comprising:
- a mounting base, a lock ring, and an engine mounting bracket for securing an engine to a watercraft;
the mounting base further comprising a threaded mounting bolt and a plurality of nuts including a lower nut, a middle adjustment nut, and an upper nut;
the lock ring further comprising a top surface, a bottom surface, an aperture extending through a thickness of the lock ring from the top surface to the bottom surface, an outer periphery and at least one arm downwardly extending from the outer periphery and having an inner surface for interaction with at least one of the plurality of nuts;
the engine mounting bracket further comprising a platform having a top surface and a bottom surface with an aperture configured to receive the threaded mounting bolt and the at least one arm of the locking ring extending therethrough;
wherein the threaded mounting bolt receives the lower nut, the middle adjustment nut, the engine mounting bracket, the lock ring and the upper nut such that a bottom surface of the engine mounting bracket engages the middle adjustment nut, the bottom surface of the lock ring engages the top surface of the engine mounting bracket platform with the downwardly extending arm of the lock ring extending through the engine mounting platform aperture and engaging the middle adjustment nut, the threaded mounting bolt extends though the apertures of the engine mounting bracket platform and locking ring, and the upper nut engages the top surface of the lock ring preventing rotation of the middle adjustment nut;
wherein the middle adjustment nut has an outer surface with a plurality of wrench flats and transition points therebetween, and the inner surface of the downwardly extending arm on the lock ring is concave to engage the outer surface of the middle adjustment nut at either a wrench flat or a transition point of the middle adjustment nut; and
wherein the lower nut is rotatable to create a downward force on the mounting base.

Abstract
A mounting assembly for a stern drive engine including a mounting base, an engine mounting foot or bracket for securing an engine to a watercraft, and a lock ring for securing the engine mounting bracket in a constant position relative to the mounting base. The mounting base includes a threaded mounting bolt to receive a first adjustment nut, the engine mounting bracket, the lock ring and a second nut. The bottom surface of the locking ring engages a top surface of the engine mounting bracket with a downwardly extending arm or arms of the lock ring extending through an aperture in the engine mounting bracket to engage the first adjustment nut. The threaded bolt of the mounting base extends through apertures of the engine mounting bracket platform and mounting ring, and a second nut engages the top surface of the lock ring, preventing rotation of the first adjustment nut, and ultimately limiting movement of the marine stern drive engine.
