Mercury - Resistor Pack #98 Quad DTS Shadow Mode Shadow Load Module 898091T04. OverviewThis 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 Feature
