Mercury - Hardware Bag Assembly LCM Mounting Kit with Isolation 56-820386A85. OverviewThis kit has the little pieces you need to mount a Legacy Command Module without letting it take a beating. The rubber isolators help keep vibration from running straight into the module, which is a big deal on boats that see real chop. It also keeps the LCM from shifting around or buzzing in its bracket. It's simple hardware, but it makes the whole setup feel sturdier and more put-together.. Key Features • LCM
