Check the watter shutter. When they go it sounds like an intermittant
rattleing noise. The noise usually goes away after the engine warms up.

BUMP....
Just wondering if maybe it got missed 
Thanks,
Hey all... I wish I could give back what I get from this group...
Anyways,
I'm having another problem...a small one I hope... when I'm in gear
(havn't
tried in reverse) and above 1000RPMs I hear a kind of a rattleing
clanging
noise coming from the back end... my thoughts are U-Joints and Gimbal
(as
I
didn't replace them when I did the bellows') It seems to getting mildly
worse as I use the boat more... it's a 77 Mercruiser 140... If it turns
out
to be the U-Joints, do I need to replace just the U-Joints or do I need
to
replace the whole shaft?
Thanks a lot again!
