I am getting a grinding metatalic feel /sound when I exceed 1200 rpms on starbord side. I noticed this on the weekend. When I opened the boat up port engine was reving at 3800rpm and starbord engine was reving at 2500 rpm. In neutral both engine rev and sound fine. Seems to be a little drag on...
When I exceed 1200 rpm my starboard Cat 3208 I hear or feel a grinding sound. When both motors are opened up the starboard enging is reving at 2500 rpm and the port engine is about 4000 rpm. Any info would be appreciated.
