Remanufacturing Lower Units with OEM Parts

When your boat lower unit starts experiences issues or is damaged from impact, replacing it with a brand new one can often end up being very costly. But did you know that there’s a more cost-effective solution? Remanufactured lower units, also sometimes referred to as rebuilt lower units, offer a great alternative! They’re essentially lower units that have been put through a rigorous remanufacturing process to ensure they match the performance of brand new units, at a fraction of the cost.

During the remanufacturing process we follow a series of important steps to insure we build the best quality lower unit on the market. Those steps include disassembling, cleaning, replacing worn-out parts and components and then reassembling the unit.
It’s important to note that the quality of remanufactured lower units will differ based the remanufacturing procedure used among other producers. So, it’s vital to purchase from a trustworthy and reliable source and to read through reviews from other boaters who’ve had experience with the remanufactured units.

Apart from the significant cost savings, opt for remanufactured lower units because they are eco-friendly. By recycling used parts, remanufactured lower units help reduce waste, making them a sustainable choice for your boating needs. So, be rest assured that remanufactured lower units provide a fantastic opportunity to save money while delivering the performance you require for your boat!
