2 Product Questions

Is this the correct replacement ignition switch for a 75 mercury SN# IB066352?

Jason

Answer:

This is the most common switch for Mercury outboards. However, you may want to confirm the part number using the diagrams for your specific remote control. Your engine serial number does not specify what remote control was used by the boat manufacturer.

Is this the push in (primer/choke) key ?

Chris

Answer:

Yes, this ignition switch does have the push-to-choke.

Problem fixed: BATTERY VOLTAGE WOULD DROP FROM 12.5VDC TO 10VDC WHEN TURNING TO START

Getting difficult to find the correct part for a 23 year old outboard at a fair price. Crowley had the correct switch, wire color changed some over time and it was a breeze to swap out. Matched all the colors but 2 and guessed correctly the 1st attempt. Have purchased parts from Crowley in the past, they always have the part and shipping is quick.

Great customer support with tech questions

Problem fixed: Key switch did not work and blew fuse due to water in old key switch

Simple job of cutting out older key switch one wire at a time and reconnecting new wires of new key switch! took about 45 minutes total.

Clear, quick and easy service. Best of all there was an error in my delivery, but once I flagged it, parts arrived next day. This is when you know a company is good. Many thanks.

Problem fixed: Ignition switch stiff and hard to turn and not making good contact on start-up .

Removing and replacing a ignition switch is no easy task especially with the possibility of not getting an exact replacement. After receiving my new switch i unpackaged it and found it to be a exact match this made the replacement much easier because i just followed the OEM wiring schematic .
