The Sierra 18-99391 Timer Base is a precision ignition component designed for Johnson/Evinrude outboard motors. This timer base replaces OEM part number 583533 (CDI 133-3533) and is engineered to deliver reliable ignition timing for optimal engine performance.
Key Features:
Fits: 1988-2001 Johnson/Evinrude loop-charged outboard engines in 185, 200, 225, and 250 HP configurations equipped with CDI ignition systems.
This timer base is a critical component of your outboard's ignition system, housing the trigger mechanism that signals the CDI unit to fire the spark plugs at precisely the right moment. Sierra Marine parts meet or exceed OEM specifications for reliable performance on the water.
Super smooth transaction, and fast delivery. Just waiting for my mechanic to open packages and verify all correct parts, but I don't expect any issues. Would definitely purchase and recommend others do business with Motorsport.com again

Enjoying the product but the dividers in the box were difficult to put in, and didn't fit well.
