Four Winns 1996 Sundowner 205, 5.1fi engine (Volvo Penta)

When engine passes 2200 RPM, throttling up OR down, the engine makes a shudder *sound* - not necessarily a vibration, although there is a very slight one.

It sounds ugly to the ear, like things are rattling in there, but once at 2300 or above it purrs like a kitten. Same for anything 2100 or below.

I uploaded an MP3 audio if you want to hear it. I will admit it's not the greatest audio, but it does capture the *groan* as I throttle through. Listen for it at:

:03-:05 seconds
:09-:11 seconds
:13 seconds
:18-:21 seconds

Hear it: http://home.comcast.net/~catdiary/fourwinns.mp3

Thanks!

I can't hear anything odd in that video, sorry.
Check the usual bits like power steering pulley bearings, alternator bearings, uni joints, engine mounts, oil levels etc. as a start...

I moved this topic to ENGINE index -- this was inadvertantly placed in Funship. Didn't mean to do that - sorry. deafwish - thanks for the note. I will do those things.
