vibration

Hey, did you know these boats actually sail too? You wouldn’t know it watching me over my first 4 months of ownership, but we were finally able to take Segue (soon to be renamed) out for the day. I had a small scare when I went below to find the new exhaust riser smoking a bit when I was...

I recently purchased an Ericson 34-200 and the surveyor identified excessive vibration. A new 2-blade Maxprop feathering propeller was installed about two months ago by the previous owner and it feathers easily. The strut bearing shows no sign of wear. The propeller shaft is slightly stiff to...

Hi, I would appreciate any thoughts and advice on this new problem. We replaced the Hurth transmission on our 1984 E30+ with a Twin Disc transmission, rated at the same 2:1 reduction ratio (whatever that means:confused:) because it seemed the Hurth was slipping occasionally when underway...

I'm new to this game as a 1st time boat owner and loving my 1977 E32. It has an Atomic 4. The boat has spent it's life on the Great Lakes and is now in Milwaukee. I have a vibration under power that begins to be noticable at about 1,700 RPM. At 2,000 the vibration is seemingly 4-5X the...

This weekend while anchored at Catalina we had fairly brisk winds. During the night we felt the mast shudder. Very quick and brief but it happened many times over many nights. Any ideas? John

Hi All, I recently posted regarding a cyclical vibration I'm getting. "It cycles on and off on with a regular rhythm. It lasts maybe 3 seconds, goes away for 3 seconds and then comes back for another 3. I do notice it happens more when the boat rolls from side to side. I just pulled the...

Hi All, Just wondering if anyone has any ideas on the engine vibration we're getting. I've noticed it a bit more over the past few months. It cycles on and off on with a regular rhythm. It lasts maybe 3 seconds, goes away for 3 seconds and then comes back for another 3. I do notice it...

Last time I came out I put three of those bulky zincs on the shaft (I know, overkill), replaced the cutlass bearing and installed new a R&D Flexible Coupling and a PSS Shaft Seal. The vibration was really bad. The dripless bearing (PSS)was shaking so much that it was a shower down there...
