Bellows on a boat are flexible gaskets that protect the boats engine and internal systems from getting wet. They have a watertight seal to prevent rusting, and their accordion shape provides flexibility. Bellows are necessary because boats use an open-water cooling system, which means they dump heat from the engine outside, keeping the engine cool. However, while this system is fantastic at its job, it leaves some engine components vulnerable to water. Bellows are located around the shift cable, U-joints, and exhaust on stern drives, and they contain a pesticide that prevents wildlife from biting the rubber elements. Here are some signs that your bellows need replacing:

• Boat leaking: If your boat is leaking, a loose gasket or crack might be the answer.
• Difficulty steering: If youre having trouble steering your boat, it could be due to a damaged bellows.
• Unusual noises: If you hear unusual noises coming from your boat, it could be due to a damaged bellows.
• Visible damage: If you can see visible damage to your bellows, such as cracks or tears, its time to replace them.

Its important to keep an eye on your bellows, as they are a vital part of your boat. They keep it healthy and running smoothly, and they make sure you are safe out in the seas.
