Mercury – Resistor Pack #98 Quad DTS Shadow Mode | Shadow Load Module | 898091T04

Overview
This resistor pack is used on quad-engine DTS Shadow Mode systems that run two helms. It keeps the network load where it needs to be so Shadow Mode stays smooth and the engines respond in sync. This #98 version is the one placed at Helm 2 and Port 2 on dual-helm quad setups. It’s a small electrical part, but it plays a big role in keeping the whole Shadow system steady on 2006-and-newer DTS boats.

Key Features
• Shadow Mode Resistor Pack #98 – Provides the correct load for dual-helm quad DTS systems.
• Helm 2 + Port 2 Placement – Built for the specific resistor positions in quad layouts.
• Quad-Engine Ready – Designed for four-engine Shadow Mode configurations.
• Dual-Helm Use – Supports upper/lower station setups.
• OEM Spec – Made for Gen I DTS boats, 2006 and newer.

Engine & Boat Compatibility
• Digital Throttle and Shift Gen I
• Quad engine
• Dual-helm rigs
• Shadow Mode control (2006+)

Performance & Practical Benefits
With the right resistor load, Shadow Mode stays smooth instead of drifting or hesitating between engines. Quad-engine timing—especially at slow speeds or while docking—feels more even because the system isn’t fighting a mismatched electrical path. And since the resistor sits where the network expects it, troubleshooting and long-term reliability both improve. It keeps a complex system from acting unpredictable.

Why Buy OEM
OEM resistor packs are built to Mercury DTS specs, so you’re not guessing at values or dealing with flaky timing issues. They handle vibration, heat, and moisture better than generic parts. In a quad-engine Shadow Mode setup, using the correct OEM load module makes all the difference.

FAQ
Q1: How do I know I need this resistor pack?
A: If you have a quad-engine DTS Shadow Mode setup (2006+), this #98 pack is the one used at Helm 2 and Port 2.

Q2: Any calibration after installing it?
A: No—plug it in and the DTS system handles the checks itself.

Q3: How does it hold up in saltwater?
A: Very well. Just rinse occasionally and keep an eye on the connectors.

Q4: Any installation tips?
A: Make sure the resistor is fully seated so the load stays stable and the system reads it correctly.

Q5: What are early signs something’s off?
A: Uneven Shadow Mode timing, small delays between engines, or occasional dropouts in control response.
