Wheel drive bulkhead mount bracket

[Chuck - Raymarine - Moderator]

Randy,

When installed properly, it is not expected that the bracket will permit much, if any movement of the drive's motor housing. Accordingly, Raymarine has not specified drilling an oversize [censored] to accommodate movement of the drive's motor housing. That said, you may want to consider making the [censored] slightly larger than the motor's housing to prevent contact between the motor's housing and the bulkhead, thereby minimizing the chance of noise associated with motor vibrating against the bulkhead when operating the drive. The void may be filled with a flexible sealant which would prevent such noise.
