Does this power pack have an RPM limiter?
The catalog application for this power pack is listed as having no RPM limit. This does not change any separate RPM limits or operating requirements specified by the engine manufacturer.

Is this an OEM part?
No. This listing is for an aftermarket replacement power pack. The OEM and aftermarket reference numbers are supplied only to help verify the intended application.
Can I install it myself?
Installation should be performed only by someone familiar with outboard ignition systems and the correct service information. Disconnect power before working on the wiring and verify all connections before testing the engine.
