Availability Notice
This part (801285058) has been discontinued by Mercury Marine and is no longer available as new stock. If you require a distributor cap for your MerCruiser engine, please confirm whether a current replacement cap or cap-and-rotor kit is available for your specific engine model, serial number, and ignition system type. See the related products below for current MerCruiser distributor cap and rotor kit options that may apply to your engine.
About This Part
The 801285058 / 12111285058 was a Mercury Marine OEM distributor cap used on selected MerCruiser engines equipped with Bosch-style distributor ignition systems. The cross-reference number 12111285058 corresponds to the Bosch component identifier used in earlier MerCruiser ignition applications. Distributor caps on these systems route high-voltage spark from the ignition coil to each cylinder in firing order via the rotor and spark plug wires.
Compatible Applications
Fitment must be confirmed by engine model, serial number, and ignition system type. This cap was used on selected older MerCruiser engines equipped with Bosch-style distributor ignition. Because this part is discontinued, confirm availability and check for current replacements using your engine serial number before sourcing.
When a Distributor Cap Needs Replacement
- Visible carbon tracking, cracking, or moisture damage on the cap body
- Burned, corroded, or worn terminal contacts inside the cap
- Engine misfiring or rough running under load
- Hard starting or no-start condition with the distributor ignition system
- Scheduled ignition service interval
- Water or condensation has entered the cap
Installation Notes (General)
- Disconnect the battery before working on the ignition system
- Mark or photograph spark plug wire positions before removal to ensure correct reinstallation in firing order
- Inspect the rotor, ignition wires, and coil while the cap is removed — replace worn components at the same time
- Inspect the distributor shaft and advance mechanism for wear
- Clean the distributor housing sealing area before fitting the new cap
- Follow the Mercury service manual for ignition timing verification after reassembly

If you’re searching this part number, you’re likely working on an older engine and the cap is either cracked, has carbon tracking, or is failing under load. Since this cap is no longer available new from Mercury, the best approach is to confirm your engine model and serial number and check whether one of the current cap-and-rotor kits listed above covers your application — many older MerCruiser ignition systems have current-production cap and rotor options available.
