MotorGuide Mounting Isolator Kit, 4-Pack, Stainless Steel Bolts

Overview

The MotorGuide MGA015PB6 is a mounting isolator kit that helps absorb shock and cut down vibration when you bolt marine accessories in place. It is commonly used for trolling motor mounts and other deck mounted hardware where vibration can work fasteners loose over time and where you want a cleaner install without needing full access under the deck or behind the console.

The kit uses rubber isolators with a molded-in nut and stainless steel bolts. As the bolts are tightened, the isolators expand into a mushroom shape under the mounting surface, helping the mount clamp down securely while the rubber takes the edge off impacts and vibration.

Key features

• Rubber isolators help reduce vibration transfer into mounted electronics and accessories.
• Molded-in nut in each isolator simplifies tightening from the topside.
• Isolator expands into a mushroom shape as it is tightened to help hold the mount in place.
• Useful for installs with limited underside access under decks or behind consoles.
• Stainless steel mounting bolts included for a clean bolt-through installation.

What’s included

• 4 rubber isolators
• 4 stainless steel bolts
• Mounting instructions

Installation and setup

Lay out the mount, bracket, or accessory base and confirm your hole pattern and clearance before drilling. Insert the rubber isolators through the mounting holes, start the stainless bolts, then tighten until the rubber mushrooms under the surface and the assembly feels firm. The goal is a stable clamp with the rubber still doing its job, not crushing the isolator.

After the first run, recheck fastener tightness. Vibration and deck materials can settle slightly, especially on the first outing after installation.

Compatibility and fit

This kit is intended for bolt-through mounting applications where you want some isolation between the mount and the boat structure. It is a good match for trolling motor mounts and many other marine accessories that use standard bolts and washers for deck mounting. Confirm your deck thickness, hole size, and the space available below the mounting surface so the isolators can expand properly.

Use cases on board

It is a practical choice for bass boats, bay boats, and center consoles where you are installing gear on the bow deck or near the console and access is tight. It can also be helpful on boats that see chop regularly and where sensitive electronics benefit from reduced shock transfer.

Materials and corrosion resistance

The isolators are rubber and the fasteners are stainless steel. The rubber helps isolate vibration at the mounting points while the stainless hardware suits typical wet, salt, and washdown conditions when installed with normal marine best practices.
