Expertly built in the USA
Typically, our builders will assemble the lower units in batches of a single model. Building multiple identical gearcases at the same time ensures accuracy and consistency across the board. It also allows us to keep plenty of inventory for each model.
In stock, ready to ship
Utilizing 3 large warehouses allows us to keep plenty of lower units on hand and ready to ship. Because of our large inventory, most lower units will ship out the very same day you place the order. We also keep a very extensive inventory of gearcase cores. This allows us to quickly build more gearcases when particular models run low on inventory.
All of our lower units are packaged with expandable foam. Our complete line of lower units ship using standard UPS or FedEx ground service. Expedited and international shipping options are also available.
12 month warranty
All lower units, whether Crowley Marine brand or OEM include a full 12 month warranty. The majority of our customers never have any issues with their lower unit or installation, however in the rare case something does arise you can rest assured that you will be covered.
