In the time that I worked as an assistant in a boat mechanic’s workshop, I learned a great deal about the intricacies of boats and boat maintenance. Not only did I learn about the inner workings of boats themselves, but I also learned a lot about what types of items were used when mechanics did boat maintenance. I particularly remember learning about the brands they trusted.
The brands of outboard motor oil that they tended to trust the most were Yamaha, Mercury, and Evinrude. The things that I learned while working in that shop have carried over to my own life now that I have a boat of my own, so I always know what sorts of things I need to purchase when doing maintenance on my boat.
