The OML Motor Loc Volcano Lock twin pack is our premium outboard engine bolt lock. This is our new twin pack design using the same keys for both locks. OML locks are now regarded by many in the industry as the best bolt locks on the market to prevent outboard theft, as it has been designed and built to resist criminal tube jemmying and sawing. We always recommend fitting two locks on any large outboard for added security.
Any outboard that is bolted through the transom to include
EVINRUDE: 40-250hp and upwards
HONDA: 40-225hp and upwards
MARINER, MERCURY: 25-275hp and upwards
SUZUKI, JOHNSON: 25-300hp and upwards
TOHATSU, NISSAN: 40-115hp and upwards
YAMAHA, SELVA: 25-225hp and upwards
Our tried and tested OML bolt locks are intended for use with through-bolts that are coach, countersunk or stepped so that, should a thief attack the head of the bolt and remove it, they will be unable to hammer the bolt shank through the existing hole.
