1.5" Split Conduit Outboard Rigging Tube - SPLITTUBING-15

What This Split Conduit is Used For

SPLITTUBING-15 is used to organize and protect an existing outboard rigging bundle without requiring every component to be removed from the engine or boat.

Depending on the installation, the conduit may be used around:

• Engine wiring harnesses
• Battery cables
• Throttle and shift cables
• Fuel hose
• Hydraulic steering hoses
• Gauge and network wiring
• Trim wiring
• Accessory wiring

Why Choose Split Conduit?

Traditional closed rigging tube normally requires the installer to feed the wiring, hoses and cables through the tube.

Split conduit opens along its length, allowing it to be installed around an existing rigging bundle.

This makes it a practical option when:

• The outboard is already fully rigged
• You do not want to disconnect engine harnesses or hoses
• The existing rigging needs additional abrasion protection
• You are cleaning up an older transom installation
• You need to replace deteriorated protective tubing
• You want easier access for future service

Installation Tips

• Measure the complete rigging bundle before choosing 1.5" or 2" conduit.
• Do not tightly compress fuel hose, hydraulic hoses or control cables.
• Wrap the conduit around the bundle rather than forcing components through it.
• Leave sufficient slack for full outboard steering movement.
• Check trim and tilt operation before finalizing the routing.
• Avoid sharp bends in the completed rigging bundle.
• Keep the conduit clear of sharp transom edges.
• Inspect the individual wiring and hoses for chafe before covering them.
• Replace damaged rigging components rather than simply covering the damage.

When Should Split Rigging Conduit Be Replaced?

Inspect the conduit during routine engine and transom service.

Consider replacement if you find:

• Cracked or split sections beyond the intended opening
• Heavy abrasion
• UV deterioration
• Sections that no longer stay around the rigging bundle
• Exposed or unprotected wiring and hoses
• A rigging bundle that has outgrown the existing conduit
