SHOP BY MAKE & MODEL
Please go to the OEM parts lookup to find your model number.
Once there type your serial number into the serial number box, then click the magnifying glass.
That will bring up info on the serial number and show the model number for your Motor over on the right.
Keep in mind that the model number will include engines that have different parts.
For instance, it may include bigfoot and regular foot models, so every item listed may not fit your motor.
The 1.47 ratio replaces the 1.5 ratio
