We would consider rebuilding your own unit a medium mechanic skill level project. If you are comfortable with changing brakes on a car or truck you should be fine. Buying our high-quality parts is the first step. Included with your purchase is the bonus of being able to call or text Joe at 231-631-2263 anytime for support.
How bad is metal in the lower unit fluid or oil?
The answer is in the size of the metal. If it is fine like hair it’s probably somewhat normal and is could be coming from shifting the lower unit. When you find pieces of metal larger than a broke pencil tip, then it’s time to tear it down and figure out what is wrong. This should be done before a catastrophic failure occurs.
