Please package engine properly! Damage can occur from poorly packaged engine. We are not responsible for damages occurred from shipping or poor packaging.
We recommend a strong 18-20 gallon Rubbermaid tote with many layers of cardboard and/or bubble wrap under and around the engine, and zip tie the cover to the tote. This makes a strong and easy to carry container for your engine. Stuff/wrap enough cardboard/bubble wrap around the engine so it cannot move inside the container.
