Explanation:
The Following Trim Housing Components are Individually replaceable:
The trim belt and lift belt are replaceable without replacing the complete trim module.
- The Lift Belt is the large belt that runs along the Shaft of the motor from the Control Box to the Motor Lower Unit, running through the Trim housing.
- The Trim Belt is a Small Belt inside the Trim Housing, it is driven by the Trim Motor and drives the worm gear that actuates the lift belt.
The Trim Belt should have its tension reset or be replaced when there are indications the Trim Motor is attempting to run but the motor is not trimming, or has noise, especially a ratcheting noise, coming from the trim housing during trim function. Case XVI in the Ulterra Repair Manual includes instructions regarding trim belt replacement.
Lift Belt replacement is indicated when there is apparent damage or wear visible on the Lift Belt and no other trim housing issues that would indicate the trim housing should be replaced. Case XVII Includes the instructions on Lift Belt Replacement.
Exceptions:
- On RT Ulterras, if the trim housing is a revision prior to implementing Monel (Silver Colored) slip rings the consumer is best served by replacing the complete trim housing assembly.
Note: This change only applies to RT models, on Freshwater models copper rings are still used.
- Any Trim Module that upon removing the top cover appears to have had water intrusion the complete Trim Module should be Replaced.
