Common Concerns Answered
Will these shims provide enough angle adjustment for my specific needs?
While effective for minor adjustments, significant angle changes may require the use of multiple shims. It is advisable to consult your outboard motor's manual or a marine mechanic to determine the required shim thickness for optimal performance.
How durable are these shims in extreme marine conditions?
Constructed from durable materials suitable for marine environments, these shims are designed for longevity. However, as with any component exposed to harsh saltwater and high stresses, regular inspection is recommended, and performance in exceptionally extreme conditions may vary.
Is compatibility with my specific outboard motor model guaranteed?
These shims are designed to be compatible with a wide range of transom-mounted outboard engines. However, verifying the transom mounting bolt pattern and ensuring adequate clearance for the shim is crucial for proper fitment with your specific outboard model.
Frequently Asked Questions
What are Johnson Pump Transom Shims used for?
