How often is everyone doing a shaft alignment ? (yearly)
Also, what are the signs that's it's time to do one ?
It's been 2 or 3 years since we did one on my boat.
Other than some slight vibration through the deck one thing that really was different / improved the last time we lined up the engine to the shaft coupler was how quiet the boat was after.
Seems my boat is pretty loud now and I'm thinking it's time to line it up.
Thoughts , suggestions , input ?
