Vibration at idol... what's "normal"?

[G. Arruda]

Hi All,
Have a New 07 Glastron MX175, 3.0 Volvo SX , 25 hrs on it ... How much vibration is normal for my motor??? Have a pretty high freq. vibration at idol, at operating temp. Nothing in gear, turning triming, just seems like it's more vibration than "normal". It's done this from day one.
Now, the only thing I have to compare to is an 88 17' FourWinns (heavier, wood floor/stringers, etc) My dealer says it's pretty normal, but it's still got me think'in
Any comments would be really helpful
Thanks!

NORMAL is a relative term. I think you answered your own question. Compared to another boat.
If the engine is running right, you have what you have. Weight and structural mass makes a big difference.

Thanks for the response... make sense, but I'm told that these Volvo 3.0 "just have some" vibration @ ido... I don't know anyone else out there w/ a pretty new 3.0 SX that has normal vibration??
