Anything with “Marine” in its title, is usually 5X more expensive, but worth it.

Nothing sucks more than having the engine crap out, 150Km offshore, because your fuel injection system got corroded.

Hell, anything even close to salt water is apt to get ate. What's funny is you'll see people say they want to retire and get a beach house. No. You. Don't. Blowing sand is hard on stuff, getting in gears and moving parts. But the salt, the salt is like some alien monster that just dissolves things that flat landers would never expect. Get the smallest amount of saltwater flooding in a closet with equipment and things start to corrode away like it's an alien acid world.
