So, you're looking to keep an eye on your twin outboard or stern drive?

This Sierra International 4-gauge add-on kit is exactly what you need.

Sierra's been making marine parts for 50 years, so you know they get it right – their stuff meets or beats OEM quality and handles the tough saltwater life.

This Arctic Twin set comes with four gauges: a tachometer/hour meter (to track RPMs and engine hours), an oil pressure gauge, a water temperature gauge, and a voltmeter.

That's pretty much everything you'd want to monitor to keep your engine healthy and avoid surprises out on the water.

They're built tough to resist vibration, moisture, and UV rays.

The best part?

Sierra backs it all with their lifetime customer satisfaction warranty.

If anything's defective, they'll fix or replace it, no charge.

It’s a straightforward upgrade that gives you way more info than your basic dash might show, and it’s designed to look and work like it came with the boat.
