Expensive but welcome to owning a boat
It is a good size to easily store on the boat. They have multiple sizes depending on your boat size. Expensive but if the word marine is on its expensive

Good product.
Perfect replacement. God boarded by the coast guard on a routine check and they said it was a good product. Make sure you buy the correct size for you boat. Over certain sizes require a bigger extinguisher.
