Tips & recommendations for replacing your gearcase lower unit.
It happens – just plain bad luck – hitting an underwater tree stump, rock or other invisible debris & your lower unit is shot. After you get towed safely back to shore and have a chance to regroup, what are your next action steps? We have written this article to outline the step you should take if you damage your lower unit. Use this as a reference tool as you navigate through the process of repairing or replacing your gearcase lower unit.
First off, if you think you have damage to your lower unit but are hoping that it will be okay if you ignore the problem, be aware that internal damage to your unit may not be noticeable right away. Slightly damagedgears may seem to work fine at first but over time the off-kilter gears will wear away and cause eventual failure. We recommend you have your motor diagnosed thoroughly to determine if you have internal damage. Check out this forum for further evidence: What smacking a boulder does to your lower unit gears.
We recommend calling the insurance company that has your boat policy before you do anything. Some policies will cover accidental damage to your drive.

The choices you have when replacing a lower unit include a brand-new OEM unit, a remanufactured OEM unit or a new aftermarket unit. I will discuss the pros and cons of each below.
Brand New Manufacturer Unit
This unit is made by your motor manufacturer and will contain original OEM parts. Quality manufacturing is a guarantee and the unit will come with a nice warranty. Warranties will vary by manufacturer so please check with a knowledgeable dealer regarding the warranty.
- More expensive
- Warranty depends on manufacturer
- All parts are OEM
- Outstanding quality drive
- Usually ships in 24 hours
New Aftermarket Lower Unit
The new aftermarket lower unit is usually manufactured in China. The quality control is generally lacking on these units. The up side is that they are significantly cheaper and some aftermarket manufacturers give a great, 3 year, fault free warranty. While this warranty is nice, it is a pain in the neck to deal with replacing the unit under warranty. There is the obvious down time associated with diagnosing the problem, calling the manufacturer for warranty replacement, placing a replacement order, waiting for the unit to be delivered then waiting on the boat shop to install the unit. Do your homework before purchasing an aftermarket unit!
- Better prices compared to OEM Lower Units
- Made overseas where quality control and trained mechanics are lacking
- 3 year, fault free warranty from certain manufacturers
- Built new to manufacturer specifications
- Includes all internal parts & is fully compatible and interchangeable with OEM drives

Remanufactured Lower Unit
A rebuilt or remanufactured unit should be built by quality, trained mechanics with OEM parts. These units offer the best of both worlds, giving you OEM parts, a unit assembled by trained mechanics in the US and a nice price savings over new OEM units. This option is the preferred choice of most boaters.
- Priced at deep discounts to save you money
- Rebuilt by trained mechanics in the USA
- Units usually include a full 1 year warranty but this will vary
- Built new to manufacturer specifications
- Includes all internal parts & is fully compatible and interchangeable with OEM drives
