Motorloc The Volcano Bolt Lock

Product Overview

The Motorloc Volcano Bolt Lock is an insurance-approved, heavy-duty outboard engine security device designed to prevent theft of through-bolted outboard motors. Built from tough marine-grade stainless steel, it is widely regarded as one of the most secure bolt locks available for larger outboards.

Key Features & Benefits

• Maximum Theft Deterrence
  Engineered to resist aggressive theft techniques such as jemmying, cutting, and sawing.

• Insurance-Approved
  Recognized by marine insurers as a high-security device and often required for policy compliance.

• Marine-Grade 316 Stainless Steel
  Offers superior resistance to corrosion, ideal for saltwater environments.

• High-Security Lock Mechanism
  Durable, weather-resistant lock cylinder with two keys included.

• Designed for Larger Outboards
  Suitable for a wide range of engines from major brands including Honda, Suzuki, Yamaha, Mercury, Mariner, Evinrude, Tohatsu, Selva, and more (typically 25–300 hp depending on model).

• Through-Bolt Protection
  Specifically engineered for engines bolted through the transom. Even if a thief removes the bolt head, the lock design prevents the shank from being hammered out.

• Easy to Fit
  Simply slides over the existing outboard mounting bolt and locks in place.

Why Choose the Volcano?

Outboard engines, especially high-horsepower models, are prime targets for theft. The Volcano provides serious peace of mind thanks to its solid stainless-steel construction and proven resistance to attack. Because it’s insurance-approved, it serves both as a strong physical deterrent and a compliance tool for insurance policies.
