In July 2014 a pleasure boat I am a part owner in was involved in a grounding accident. This resulted in significant damage to the hull and running gear. The props, shafts and gearboxes were all badly damaged and had to be replaced. During the accident significant stress was placed on both engines. Both engines have only done a reasonably low 600 hours of running time. A marine insurance claim was placed which resulted in the repair and replacement of the damaged components. The repairs were completed and the boat was returned to an operational condition. Now, after only 70hours of running time since the accident, the port engine has experienced a critical failure which is likely due to the stress from the accident. The insurance company are not of the same belief. Are there any grounds for tying the current incident to the original claim?
