Hi everyone... The "Knot Working" really hasn't been working much at all this summer. In fact I haven't had a single trouble free day on the water since I took delivery of her in mid June. I have recurring issues that continue to stump the master technicians at Russo Marine in Boston. One of the newer issues is a LOUD squeal/chattering/bearing noise coming from the starboard side engine and while the engine rev's around the dock while using Axius. The squeal went away after they replaced the belt, but there is still a chattering/bearing noise right as the engine makes a cold start then I don't hear it anymore. Also the bilge has rust stain under the pulleys that has been getting bigger and is now in a linear form (almost like the water is slingshotting off the pulley). Here is a picture below, does this sound like a failing circulating pump?
