What Is Boat Rigging?

What is boat rigging? Rigging is the process of configuring a boat to best suit the customer’s needs and following manufacturer recommendations. This process is different for each type of boat. This blog will explain how outboard rigging works.

How to Rig a boat: Outboard Rigging

The process of “rigging” an outboard is more than just bolting it to the transom. This includes connecting the steering, throttle, shift, navigation, and communication systems to the engine control systems.

The following can be used to rig outboard engines:

Locate the Transom Center

You must locate the transom center using the arc method to rig an outboard motor. You will need to find the transom center using two points that are identical. Next, use a straightedge and draw an arc at the top of your transom.

Use the same reference point to the opposite side of your transom to create a second arc which crosses the transom’s centerline. You can repeat these steps with the same reference points, but you will need to move three to four inches along the straightedge in order for the second arc.

Engine Spacing

Both single- and dual-engine engines require engine spacing. This allows for clearance to ensure that the motors don’t interfere with each other when they pivot on their steering or tilt axes.

For a single engine, position them along the transom’s centerline. To allow full turning radius, offset dual engines by a minimum distance from the transom’s centerline.

Drilling the Mounting Holes

Start by choosing the right hole pattern for the engine you are mounting to drill the mounting holes. Before you begin drilling, make sure to inspect the transom for any damage that might occur during drilling.

Make sure that you only have access to the inside of each hole. Also, ensure the top hole is not more than the recommended distance below the transom. The drill bit should be held at 90 degrees to the transom.

Determining the Height of the Transom

Measure from the top of your transom to where the engine centerline is at the bottom of your boat. Choose the right length engine shaft and align the anti-ventilation plates so they are level and at the appropriate distance relative to the bottom.

A higher engine mounting height can lead to decreased steering torque, improved boat stability, better propeller ventilation, and increased maximum speed.

Uncrating Your Engine

Start by taking photos of the engine in its entirety to show any damage. Verify that there are no missing parts. This is the responsibility of the manufacturer.

Place the crate in a position as indicated by the manufacturer’s crate markings. Once the cardboard is removed, unpack any accessories and place them aside. For uncrating instructions, refer to the manufacturer’s service manual.

Mounting the Engine

For proper engine mounting, ensure that top holes are no less than the recommended distance from the transom surface.

Before mounting the motor, mount the steering cable to it. Match the positions of the upper and lower bolts. The upper mounting bolts must be installed in the top hole. If not, the lower bolts must be installed at the bottom slot. Next, insert the mounting bolt through the transom.
