Doing It Right the First Time

At times, depending on the complexity of a repair job – simply reading a repair manual or a blog by some guy half way around the world using questionable tools just does not cut it.

As boat owners, we know how time consuming and expensive repairs can be. Performing the job correctly the first time around will save you not only additional money, but valuable time. Hours or days can be lost repeating a job that may have simply missed a step due to misunderstanding the instructions in a manual. Those lost hours or days is lost time you could be enjoying out on the water fishing or with friends and family.

Finding Your Repair Video

Whether you own a boat with an inboard/outboard such as an OMC (Outboard Motor Corporation), a MerCruiser (manufactured by Mercury), or a boat equipped with an outboard such as an Evinrude / Johnson, Mercury or Yamaha – you’ll find the right repair video below.

Each section below is divided by manufacturer (you’ll notice easy to spot headers below), and in each section, a brief description and summary is provided for each of our most popular videos which will allow you to quickly choose the correct one for the job you are performing.
