It's the only spot on the boat you don't like looking at, but it's right in front of your face every time you're at the helm. Teleflex's Sahara gauges are an off-season upgrade for helms in need of some style in marine aftermarket work. A basic outboard box set includes tachometer, speedometer, fuel gauge and voltmeter, while a basic inboard/sterndrive set gets you a tachometer, speedometer, fuel gauge, water temperature gauge, oil pressure gauge and voltmeter. Prices start at $199.95.
