Good morning. Can anyone please ID the sensor in the pic? It is located on the engine room ceiling hatch frame, just above the heat exchanger tank, on my 1978 46C. I’ve had these hatches open numerous time and only noticed it this last time. The wires lead into a large harness and I haven’t...

Has anyone used Diesel Pro Power in Miami, Fl. for engine parts? Their website is very user friendly and they seem to specialize in Detroit Diesel and Allison, not to mention they are local to me. I have noticed though that some parts are name brand and others appear to be made in-house...

Just had a bottom survey done and my port prop shaft is almost touching the bottom of the hull fitting. It needs to go up about a quarter of an inch. This happened over the last three years since my last survey. What normally causes the shaft to go out of alignment? Sagging engine mounts...

After running the Penray online cleaner for 30 days, I flushed the engines (8V71TI) and replaced the coolant with distilled water and Detroit Diesel Powercool Plus 6000. At the dock, the engines warmed up like normal. Once under load at speed, both engines heated up to 185 simultaneously. They...

Good Evening, The squirrel-wheel blower from the evaporator that services the main stateroom on my 1978 46C has gotten loose and is making a lot of noise while running. I am wondering, which is the best way to access it? It appears to be underneath the forward "dash" area in the salon to port...

Over the weekend, the head in the master stateroom (46C series I) went down. The head, a Raritan Crown Head, wouldn't flush although the bowl would fill up. After removing and inspecting, everything was clean and clear. From what I read on this site, it is time to exchange the unit. At $600 for...

I've owned my Hatt now for about six months. The generator (Westerbeke diesel 12.5 BTDA - early '90s model) recently shut down due to a temp sensor. I proceeded to change the raw water impeller, and gave the heat exchanger a good phosphoric and oxalic acid wash which gave me much more flow, but...

I knew this day would come, but I hoped it wouldn't be after just three months of owning her. While heading back to the marina today, after running the boat (1978 46C) for about twenty miles, my starboard 8V71TI shut down. I had it synchronized at about 1700 rpm when I heard the starboard...

The salon floor planks in my 1978 46C seem to be in pretty good shape. Although, when viewed from the ER, the wooden structural support beams seem to be dry rotted pretty badly. Especially where they meet the hull sides on the outboard side of the engines. What would be the recommended type of...

Good evening, I am a long-time admirer of this site and its members. I have been shopping for a Hatteras Yacht for the last three years, and your forum has proven invaluable along the way in terms of research and what to look out for in a Hatt. My wife and I just recently purchased a 1978 46C...
