Volvo penta 4.3 engine vibrations

[crnjak]

Hello, Can someone please tell me if this is ok ? Engine works at 1000 rpm, you can see little vibrations, when it goes to 3000rpm engine is still. https://www.youtube.com/watch?v=f82s-RknzA4 thanks

It is hard to tell from the video the exact issue. If it were mine I'd be pulling the drive and inspecting the u joints and gimbal bearing.

Hard to tell but it looks like it's missing?
BTW...I would be pulling those risers and looking them over good. When they start showing leaks, it's usually time to replace.

Mine has a very similar vibration at low rpm's.... Was actually starting to look into as well as I don't remember the vibration being so noticeable before I had the carb rebuilt....

I will check carb and risers in september after season.
Risers and exshaust are 2 years old.

New gimbal bearing was installed last year and u-joint are fixed.

I have one more problem, when I do sharp turns I can hear knocking, is this normal ? Maybe bad U-joints ?

I'd say the knocking when turning is U Joints
