Sounds like a partially plugged mixing elbow, or maybe something blocking 
thr raw water someplace. Could also be a bad impeller.

Yanmar 2gm -  like open exhaust?
This just started happening this weekend.  When first started and idling the 
exhaust is noisy - like an open exhaust, maybe no water.  Run it for a bit at 
higher rpm, and suddenly it quiets down and sounds normal.  Next cold start, 
same thing.  Did a quick check of the raw water strainer underway,  and there 
was some stuff in there, but water was being sucked through.     Is the mixing 
elbow clogging?    Haven't had that off yet...  Thanks
