Sometimes the Solution is a Simple Engine Alignment

- Roger working engine mounts during an alignment
We recently got a call from a 90′ Johnson that just finished the seasonal migration from Newport to Fort Lauderdale. The Captain reported a starboard side vibration that was clearly visible in the engine room as a shaft “wobble” while underway.
A quick check with the dial indicator confirmed the Captain’s report – 0.006″ runout definitely was a problem (the port side was smooth and showed a 0.002″ run-out). Further investigation indicated the shaft was likely not bent.
A basic in-the-water alignment got the shaft running 0.002″ which is our tolerance for run-out behind the coupler. The Captain arranged a sea-trial the next day and reported all was smooth and very satisfied. A problem solved with only a half a day of work and another happy customer.
At High Seas , we believe in fixing the problem regardless of the size of the job. We will always consider simple, economical options for our customers that might save the unecessary expense of a haul-out and full shaft job. In this case, a simple engine alignment was the answer.
