1. Cost: Replacing a wrist pin needle bearing can be an expensive proposition. The part cost, as well as the labor costs for installation, can add up.

2. Installation complexity: Installing a wrist pin needle bearing can be a challenging task, especially for those without experience. Seadoo owners who are not comfortable with small engine repairs may need to pay for professional installation.

3. Risk of damage during installation: Improper installation of a wrist pin needle bearing can cause damage to the crankshaft or connecting rod. This can lead to extensive engine repairs or even replacement.

The decision to purchase a WSM 010-121 wrist pin needle bearing for a Seadoo 650, 720, 787, or 800 depends on the individual's circumstances.

However, for boats with consistent maintenance and no signs of engine wear, the high cost and complexity of the installation may not be worth it. In general, it's always a good idea to consult with a professional technician or the Seadoo dealership to determine the best course of action for your specific situation.

If you've determined that a wrist pin needle bearing replacement is necessary, it's recommended to work with a professional technician or your Seadoo dealership to ensure proper installation and engine health.
