Start with what changed
Describe when the vibration began and whether it followed an impact, removal, installation, or other service. Note whether it occurred at idle, at a particular engine speed, or throughout operation. These details are observations to share with the team, not a reason to perform further high-speed testing.
A propeller is part of a system
Bent blades, pitch variation, and imbalance can contribute to vibration. Shafts, couplers, and other running gear components may also be relevant. Repair decisions should follow an assessment rather than assuming that balancing alone will solve every symptom.
Gather details safely
Provide the vessel type, length, location, and available propeller specifications. Include existing photos or photos that can be taken safely without entering the water or moving equipment. Tell the team whether the propeller is installed and whether the vessel is afloat or hauled out.
Discuss the next step
Call to coordinate inspection and, where appropriate, removal or workshop assessment. HALE MRI measurement can help evaluate blade geometry; balancing addresses imbalance. The team will discuss which work is relevant to the findings.
