Do you want your MerCruiser’s cowling to look new and shiny for as long as possible? Yet another issue is not cosmetic but is part of your overall effort to maintain your engine. Your MerCruiser’s cowling is like the skin on your body. Just as our skin does a great job of protecting our body’s systems, your cowling protects its own precious cargo—your engine.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eJust as our skin takes a lot of abuse—sun damage, cuts, bruises, environmental contamination—so does your cowling. In the southern states, UV rays are especially intense. For example, boats and engines alike spend a lot of time baking nearly year-round in the Florida sun. In the northern states, boats may not be exposed for as many months of the year and the UV rays might not be quite as strong, but a lot of damage occurs.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eAnother source of harm is trailering. If you trailer your boat, your cowling is likely to be struck by stones, rocks, and other road debris as you tool down the highway. Scratches and dings are the low end of the damage—cracks and punctures in your MerCruiser cowling are more serious.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eFinally, environmental elements like saltwater spray or acid rain could collide with your cowling at some point.
