Can't find what you need?

There will always be more available than what's listed on the site, so you can always fill out this form to check pricing & availability. Be sure to include as much info as possible, including the OEM part number from the old part.

Not sure what a part's called?

If you're not sure what the defective part is called, just provide the best description you can, along with the OEM part number that's on the part.

Some manufacturers have different names for the same part. What Mercury calls a switch box, OMC will call a power pack, pulse pack, or amplifier--depending on model/year. Others might call it a CD module, ignition module, ignition box, etc...

What OMC calls a timer base, Mercury calls a trigger. You may also hear them referred to as sensors or sensor rings.

Gearcase and lower unit are the common terms for what some people call a foot... and the list goes on.
