Sierra Power Pack 18-5885-1, Replaces 583865, V-6 2-Stroke Outboards, 5800 RPM Limit

The Sierra Power Pack 18-5885-1 is an outboard ignition power pack built for V-6 two-stroke outboard motors with a 5800 rpm limit. It is a direct functional replacement for OEM part number 583865, restoring correct spark timing and ignition control on applicable V-6 two-stroke powerheads. The housing is metal, giving it durability for engine-compartment heat and vibration, and the unit is rated for 22 amps and 264 watts of ignition output. Sierra manufactures its ignition and electrical components to meet or exceed the quality of the original equipment they replace, making this power pack a reliable choice when an original unit fails or ignition performance becomes erratic. This is a 2-stroke-models-only power pack; it is not intended for 4-stroke applications. At 0.74 pounds and measuring 5.5 x 5.5 x 3.5 inches, it installs in the same location as the original power pack it replaces, using the existing wiring harness connections. Boat owners and marine technicians use this part to resolve no-spark, intermittent-spark, or hard-starting conditions traced to a failed power pack on a V-6 two-stroke outboard rated to a 5800 rpm limit.
