Abstract
A marine outboard engine has a cowling having at least one rear panel at a rear end of the cowling. The cowling encloses a power head. A plurality of mount points are disposed inside the cowling and adapted for rigidly mounting a tie-bar bracket. Each mount point is rigidly connected to the power head and has a bracket-mounting hole formed therein. The at least one rear panel has defined thereon a visual indication of an area to be removed to create an opening adapted for receiving therethrough a tie-bar bracket mounted on and extending from the mount points. A tie-bar bracket having a mounting portion and a tie-bar coupling portion is also disclosed. A method of assembling the tie-bar bracket in the cowling is also disclosed.

A marine outboard engine configured for mounting a tie-bar bracket, the marine outboard engine comprising:
- a cowling having at least one rear panel at a rear end of the cowling;
- a power head disposed inside the cowling;
- and
- a plurality of rigid mount points disposed inside the cowling, each mount point being rigidly connected to the power head and having a bracket-mounting hole formed therein, the bracket-mounting hole being one of a threaded hole and an unthreaded through-hole,
- the at least one rear panel having defined thereon a visual indication of an area to be removed to create an opening,
- whereby when the area is removed to create the opening and the tie-bar bracket is mounted to the plurality of mount points, a portion of the tie-bar bracket extends through the opening.
A marine outboard engine comprising:
- a cowling having at least one rear panel at a rear end of the cowling, the at least one rear panel defining an opening therethrough;
- a power head disposed inside the cowling;
- a driveshaft housing disposed at least in part inside the cowling below the power head;
- a driveshaft disposed in the driveshaft housing;
- an exhaust housing disposed at least in part inside the cowling below the power head;
- an engine block adapter disposed below the power head and rigidly fixed thereto, the driveshaft housing and the exhaust housing being disposed below the engine block adapter and rigidly connected thereto;
- a plurality of mount points disposed inside the cowling, each mount point being rigidly connected to the power head and having a bracket-mounting hole defined therein,
- the bracket-mounting holes being disposed in at least one of the power head, the engine adapter block, the exhaust housing and the driveshaft housing;
- and
- a tie-bar bracket having a mounting portion at a first end and a tie-bar coupling portion at a second end opposite the first end,
- the mounting portion of the tie-bar bracket having tie-bar holes formed therein, the tie-bar holes coinciding with the bracket-mounting holes of the mount points,
- the tie-bar bracket being mounted to the mount points by a threaded fastener received in the tie-bar and coinciding bracket-mounting holes,
- the tie-bar bracket extending through the opening in the at least one rear panel, and
- the tie-bar coupling portion extending outside the cowling rearward of the cowling,
- for each coinciding bracket-mounting hole and tie-bar hole, at least one of the bracket-mounting hole and the tie-bar hole being a through-hole.
A method of assembling a tie-bar bracket in a marine outboard engine, the marine outboard engine comprising:
- a cowling having at least one rear panel at a rear end of the cowling;
- a power head disposed inside the cowling;
- and
- a plurality of mount points disposed inside the cowling, each mount point being rigidly connected to the power head and having formed therein a bracket-mounting hole,
- the at least one rear panel having defined therein a visual indication of an area to be removed to create an opening adapted for receiving therethrough a tie-bar bracket mounted on and extending from the mount points;
- the method comprising:
- removing the at least one rear panel from the cowling;
- inserting the tie-bar bracket inside the cowling, the tie-bar bracket comprising a mounting portion and a tie-bar coupling portion opposite the mounting portion, the mounting portion having formed therein tie-bar holes corresponding with the bracket-mounting holes of the mount points;
- aligning the tie-bar holes of the tie-bar bracket with the bracket-mounting holes of the mount points;
- fastening the tie-bar bracket by inserting threaded fasteners into the tie-bar holes and the corresponding bracket-mounting holes of the mount points;
- creating an opening in the at least one rear panel at the location having the visual indication, the opening being sized and shaped to receive therethrough the coupling portion of a tie-bar bracket;
- inserting the tie-bar coupling portion through the opening;
- and
- mounting the at least one rear panel on the cowling.
