Saltwater boating is thrilling, adventurous and immersive. The feeling of braving the ocean in your own boat is both humbling and empowering. Saltwater boating is so intoxicating that humans have been fascinated the great blue frontier for thousands of years, with countless works of art depicting daring deep-sea adventures. If you’re a Crownline owner who loves saltwater boating, here is a handy list of maintenance practices that will help keep your boat running like new and ready for the next big-water adventure.


  1. Rinse Your Engine

Letting your boat sit without a rinse allows salt to eat away at your engine. The best way to combat corrosion is to rinse—internally and externally—as often as you can. Rinse the engine thoroughly with fresh water every time you bring in your boat. And to prohibit any decay on the inside, flush the engine immediately after every excursion. Cleaning is easier when it’s still wet. After the water has evaporated, the salt is much harder to remove.


  1. Use a Vinyl Protectant

To keep your vinyl in good condition, apply a protectant every 7 to 14 days. Allowing the salt, sun, heat and humidity to eat at your vinyl will quickly tarnish the beauty of your seat cushions and interior. We suggest using 303 because it also protects fiberglass, plastic, rubber and leather. Cleaning your boat as much as possible will reduce any chance of deterioration and damage.


  1. Wax and Polish Your Hull

To prevent barnacle build-up, salt decay and other types of wear and tear, wax and polish your hull two or three times a season to keep things looking sleek. These days, most hulls are painted with hard-wearing gelcoats, but it’s still well worth your time to clean and polish a few times a year to improve your boat’s appearance and maintain its resale value.

  1. More Tips

If you boat in saltwater, it’s imperative that you keep the engine in good condition. We recommend replacing your spark plugs, cleaning your fuel filter, and changing the lower unit oil once or twice a season. You should also consider replacing the impeller and fuel water separator annually, especially if you run your engine more than 150 hours a year.
