To keep your Yamaha outboard running smoothly, there are several essential tools you should have in your shed. Take, for instance, a multimeter. The small, handheld tool is used to check electrical connections. It will help identify where problems stem from.
Stabilizer, conditioner, and battery protector are also important items to have in your possession, particularly if you use your outboard in extreme climates. Stabilizer and conditioner protect against ethanol damage, as well as fuel degradation. The battery protector does exactly what its name implies. Though not strictly a tool, responsible boat owners should always have extra lubricant, like Yamalube 2M oil, on their shelves.
