Description

The Sierra Marine MP52000 is a 3-position magneto ignition switch designed as a direct OEM replacement. It is ideal for DFI, EFI, and MPI engines and features a heavy-duty potted construction for maximum corrosion protection.

This switch offers Off, Run, and Start positions with a push-to-choke function. Its molded umbrella-type key and inner seal between the cylinder lock and contact plate enhance durability. The non-conductive housing prevents potential shorts, ensuring safe operation. The switch is compatible with Mercury Marine and Mercury Sport Jet applications, replacing part number 87-88107A5.
