Thanks Jaques. Now when I ignore it I'll know what I'm ignoring.


There are only two seasons in Vermont: boating season, and boat-building season.

Use caution when ignoring. A balancer is used to offset rotational masses (think wheel weights). If you have an unbalanced rotational mass you are stressing the bearings and support structure (think wheels). If you have a prop or shaft that is unbalanced you could end up with some shakes and shimmies that are unpleasant or that lead to premature wear.

Or it could be fine...

yeah, it'll probably be fine. It's always had a vibration at certain RPM's and always been smooth at others, so I just use the smooth ones and stay away from the rough ones. Barring a real issue, it's going to remain ignored.

You could pull the prop and have it balanced. I’ve been told that most of the time it is the prop that needs tweaked.

Reminds of a few years back when my kids kept yelling at each other “I’M NOT TALKING TO YOU” for about 300mi non stop. Mile 301 they walked out of the Waffle House to an empty parking space. I was just as shocked as they were. When she finally came back no one was saying anything to anyone (in actual silence this time).

Oddly we’ve never had that particular problem a second time.

This is a solution looking for a problem. I currently have plenty of problems without solutions, so there's no need to start working in reverse. If that changes, your advice will take priority. :lol: :lol: :lol:
