Important – Please Check Compatibility

Please do not order by horsepower or appearance alone.

Yamaha produced several different ignition systems across 9.9 HP and 15 HP outboards, so not every engine within these horsepower ratings uses this CDI.

Before purchasing, please check:

Engine horsepower
Engine is 2 Stroke
Exact engine model
Production year
Engine serial number
Plug / connector configuration
Existing CDI unit
Original Yamaha part number

For the safest identification, check that your existing CDI corresponds with:

63V-85540-00 / 63V-85540-01 / 63V-85540-02

If the CDI looks the same as yours, this does not always mean it is the correct unit for your outboard.

If you are unsure, please send SSI Marine your engine model and serial number before purchasing and our technical team will be happy to check compatibility.
