Calas Performance Sea-Doo Counter Balancer

The Calas Performance Sea-Doo Counter Balancer is a lightweight OEM Rotax 4-TEC component prepared for performance engine builds, rebuilds, and repairs. Because it is an original Sea-Doo part, not an aftermarket replacement, it maintains proper fitment and compatibility with the rotating assembly.

Reducing rotational mass helps the engine run smoothly and respond more efficiently without disrupting the assembly’s balance or weight distribution. It is a practical upgrade for performance builds where reliability, smooth operation, and precise internal balance matter.

Key Features

• Reduced Weight: Cuts down heavy rotating mass inside the engine block.
• Faster Revs: Allows the motor to spin up and respond quicker.
• High-RPM Strength: Built from tough, reinforced materials to handle modified or supercharged horsepower demands.

Performance Benefits:

• Improves hole shot and cornering acceleration.
• Handles increased stress better than stock parts in race or high-boost setups.

** Important ** This service requires the customer to provide a good, usable OEM counter balancer core. Damaged cores or cores unsuitable for preparation may not be accepted.

Confirm compatibility with your Sea-Doo model and engine configuration before ordering. If you are unsure whether your core or application qualifies, contact Calas Performance before purchasing.
