It likely comes as no surprise that you need to wash your boat periodically, though exactly how often is a hotly debated topic. Most saltwater boaters agree that at least a quick scrub and rinse after each use is mandatory, while the owner of a used boat infrequently or kept under a covered dock on a clear lake may say it’s only necessary when it looks or feels dirty.

No matter where on the spectrum your usage and philosophy fall, you need to know how to wash your boat and outboard properly. Washing your boat regularly not only keeps it looking shiny and new long after you bring it home, but it also helps prevent corrosion and stains from setting in, which will allow the boat and all its parts to last longer.

If you’re not sure what you need or how to begin, this Mercury Quick Tip will tell you what supplies you need and the steps to follow for a squeaky-clean boat and engine. It also includes one of the secrets professionals use to put the showroom shine on their hulls and cowls (hint: it involves a large, soft towel) and banish hard water spots.
