Sierra 68413P Eclipse Twin Engine Add On IB/IO Gauge Kit

The Sierra 68413P is a Twin Engine Add On IB/IO Gauge Kit from the Eclipse instrument line, designed for boats that need to equip a second inboard (IB) or inboard/outboard (IO) engine with matching instrumentation. Rather than duplicating gauges the boat already has for its primary engine, this kit supplies only the engine-specific readouts a second engine needs: a tachometer/hourmeter, a voltmeter, a water temperature gauge, and an oil pressure gauge. This keeps a twin-engine dash consistent in appearance while avoiding redundant fuel or speed gauges, which remain shared across both engines.

Each gauge in the kit carries its own Sierra part number, so an individual gauge can be sourced and replaced on its own if it ever fails, without needing to replace the full set. The gauges are built with a metal housing consistent with the rest of the Eclipse design line, giving a matched look across the instrument panel. All Sierra parts are backed by Sierra's customer satisfaction warranty, which covers defects in workmanship and materials for the useful life of the product.

Frequently Asked Questions

What gauges come in the Sierra 68413P Twin Engine Add On kit? The 68413P includes four gauges: a tachometer/hourmeter (68399P), a voltmeter (68408P), a water temperature gauge (68401P), and an oil pressure gauge (68392P).

Why doesn't this kit include a fuel or speed gauge? Because the 68413P is designed as a twin engine add-on kit, it only includes engine-specific gauges; the fuel gauge and speedometer are shared across both engines and already covered by the boat's primary gauge set, so they aren't duplicated.

Will the 68413P work with an inboard or inboard/outboard engine? Yes, the Sierra 68413P is built specifically for IB (inboard) and IO (inboard/outboard) engine setups.

Is the 68413P gauge kit meant for outboard engines? No, the 68413P is the IB/IO version of the twin engine add-on kit; outboard boats need a different Sierra twin engine add on kit.

What material are the gauges in this kit made from? The gauges in the Sierra 68413P kit are made of metal, matching the construction of the rest of the Eclipse instrument line.

What are the dimensions of the 68413P gauge kit as packaged? The Sierra 68413P kit measures 13 x 16 x 9.5 inches.

How much does the Sierra 68413P gauge kit weigh? It weighs 6 pounds.

Are Sierra gauges covered by a warranty? Yes, the gauges in the 68413P kit qualify for Sierra's customer satisfaction warranty, which covers defects in workmanship and materials for the useful life of the product.

What is included in the box with the 68413P kit? The box contains four gauges from the Eclipse design line: a tachometer/hourmeter, a voltmeter, a water temperature gauge, and an oil pressure gauge, all under Sierra part number 68413P.

Is the 68413P a genuine Sierra part? Yes, it is a genuine Sierra part identified by manufacturer part number 68413P.

Can I replace just one gauge instead of the whole 68413P kit? Yes, each gauge has its own Sierra part number - 68399P tachometer/hourmeter, 68408P voltmeter, 68401P water temperature, and 68392P oil pressure - so a single failed gauge can be replaced individually.

How does the 68413P differ from the Sierra 69712P Instrument Set? The 69712P is a full Instrument Set with tach/hour meter intended to equip a single IB/IO engine, while the 68413P is the twin engine add-on kit used to add matching gauges for a second engine on the same boat.
