Quicksilver Cap & Rotor Part Numbers

[kmo058]

I have a ’99 Tige’ 2100i with a Mercruiser 350 MAG MPI Ski / 350 CID / Chevy 5.7L 350 EFI motor
& was wondering if anyone knows the part numbers for the Quicksilver Cap & Rotor. I did a search & was unable to find the numbers for Quicksilver. Want to stay with marine parts. Thanks for your help.

Did a tune up this spring and thought I would share some NAPA part numbers in case someone else needs them. The cap/rotor/coil/wires are marked as Marine and typically have the Mercruiser number in the description or details.

Coil 18-5438
Wires 18-8804-01
Rotor 18-5431
Cap 18-5395
Plugs (from my shop manual): Champion: RS12YC, NGK: BPR6EFS, Or AC-MR43LTS

Belt 25060878

Quicksilver/merc part numbers are:
Distributor cap: 805759T 1
Rotor: 13524T 1

The OldeBoy numbers are Sierra part numbers and just as good.

Cap & Rotor

Thanks for all the responses. Does anyone know what the white piece is that is being held down by the 2 screws & does it need to be replaced with the cap & rotor? Thanks again for your help.

Disclaimer: Proceed at your own risk.

I didn't replace that item.
It is listed as "sensor" in the shop manual. I would assume it interfaces with the sensor wheel fingers on the rotor.
It says that the sensor wheel fingers are not supposed to touch the sensor when the sensor wheel is rotated.
The two outer screws are mounting screws and the inner two screws are listed as adjusting screws.
To test the sensor: Disconnect the two sensor wires from the wiring harness: Using an Ohmmeter check for an ohm reading between the sensor wires. If it is less than 100 ohms replace the sensor.

Also, that is what the original sensors look like and they WILL FAIL. Replace it with the new unit that also has an additional ground wire and never have a spark problem resulting from it.
