The Mercury 0820 Sierra 18-1160 bearing kit (part numbers Rep 31-35988A2 and Rep 31-35988A12) is a common replacement option for boat owners looking to service their Mercury outboard engines. Here are some potential pros and cons of purchasing this bearing kit:

1. OEM (Original Equipment Manufacturer) part: This kit is manufactured by Mercury, ensuring a perfect fit and compatibility with your engine.

2. Includes necessary bearings: The kit contains all the necessary bearings required for a typical lower unit bearing replacement, including thrust, propeller shaft, and pinion bearings.

3. Reduces vibration and noise: Worn-out bearings can cause significant vibration and noise in your engine. Replacing them with new ones can help improve the overall performance and reduce unwanted noise.

1. Cost: Replacement bearing kits can be quite expensive, and this one is no exception. However, the quality and peace of mind that comes with an OEM part may outweigh the cost for some users.

2. Labor intensive: Installing the bearing kit requires removing the lower unit from the engine, which can be a time-consuming and labor-intensive process. If you're not comfortable doing it yourself, you may need to pay for professional installation.

3. Potential for additional repairs: When servicing the lower unit, there's a possibility that other components may require replacement as well, which could add to the overall cost of the repair.
