Engine, Generator and Gearbox Rebuilding / Reconditioning

Purbeck Marine has many years of experience rebuilding engines and gearboxes from 6hp to 1200hp, from pleasure, military, commercial and race craft.

We tailor rebuilds to suit all budgets, specifications, requirements and applications
We have a separate unit for rebuilding engines, generators and gearboxes, this is to keep the workspace clean, tidy and to give us the ability to walk away from the work whilst waiting for parts or machine work to be carried out without having other jobs interfering with the workbench/work space. We have 3 large work racks with over 100 plastic boxes surrounding our heavy duty adjustable engine rollover stand to give us the ability to strip down at least 3 large marine engines or gearboxes at any time and keep all parts organised and separate. Purbeck Marine also have a large chemical wash tank for cleaning parts.
We have purchased many tools to enable us to carry out as many jobs in house as possible to keep your cost down.
