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.
