Does anyone know what this is and what it does (see pic)? I presume it is a ground for electronics, but not sure. Can it be painted with ablative? Was painted when boat was hauled.

In need of a Fuller Brush portlight for a 1981 43 Hatteras DCMY. cut out dimensions...7" x 15 1/2"

My boat is in fresh water. Have read where anodes for fresh water should be either magnesium or aluminum. Zinc for saltwater. I'm a little confused as to whether this rule applies to all anodes, boat and engiune, or only to boat. I am changing my engine pencil anodes and not sure whether I...

Can anyone confirm that the Hynautic helm on a 1981 DCMY 43 is an H20? This was info I got from Sam's Marine parts dept. Can't find in my manual. Wanting to order a seal kit. Need to confirm the helm number. As well, anyone have experience with a SeaStar kit vs Hynautic?

Removed the valve cover on my port engine the other day and noticed oil was spewing from the pushrods on cylindders 1 + 3. Although I did not check the starboard engine, this does not look to be normal to me. Not a diesel mechanic so can't say. Anyone familiar with this occurance? Took a...

Anyone ever run into this ( see pic). I have a water leak at the transom near a bolt supporting the swim platform. Water is orange in color. I am concerned about what it has done to the transom core. This is definitely not a DIY fix. Looks like I have something else to add to the list of...

Am repairing deck core under bow pulpit and forward of bulkhead on bow. Roughly a 30 sq. ft. section or one 4' x 8' sheet. Core is 5/8" thick. Since the area requires structural integrity and the ability to bear the loads of the anchor windlass, bow pulpit and cleats, based upon all that I...

Does anyone know this motor yacht...(Top Hatt)? 1974 Hatteras 53 MY. It is listed with Knott10.com. http://knot10.com/boat-details/?BoatID=5920883 At $110K, looks reasonable. Shows well in pics (staged for sale). Located in Kent Island, MD.

Windlass is Galley Maid capstan only. Am thinking of upgrading switching to a new windlass that includes a chain wildcat. Has anyone done this with a 43 DCMY with bow pulpit? Is this a difficult change? Any threads on changing out the windlass someone can refer me to? Is anyone familiar...

Anyone have or know where I can find a Galley Maid Model BB 12 7 (Capstan only, 12V) windlass gear box (don't need motor and electricals, but will take them as a throw in)? Gears and internals should be in good working order. Some corrosion or rust on outside of case that can be cleaned up is...

Does anyone know where I can find a graving plan for a 1981 Hatteras 43 DCMY? My owner's manual is missing a plan. If someone has a copy in .pdf they can email, that would be fine as well.

My '81 43 DC is showing a bit of fade...expecially on transom where exposed to sun while under cover. However, do not think it is bad enough to need painting. (attached pic, but doesn't look as bad in pic as in light of day). Thinking of compounding, polishing and waxing with Shurhold...

Spent the last few nights reading through most of the threads on this forum about repairing/replacing the deck core and watching some youTube videos on same. Really found the thread "Galley Maid Windlass Removal" (repairs done by Dan Mapes) helpful and informative. Bought my 43 DCMY four years...

Decided I would drain and change oil today. Opened valve on oil drain plug, turned on "self-priming" pump and ..... (wait for it, wait for it)...of course, NOTHING!!! Reversible motor so just in case it was spinning in the wrong direction, I tried the other direction. No luck. I suppose the...

Would like to check on whether or not I need to replace my engine zincs. Where are they located on the engine, transmission, etc. ? What am I looking for?

I have dd6-71Ti. There is a foam filter on the turbo air inlet. I cleaned it today. What do you use to reoil it? Was thinking something like K&N filter oil or is regular 40 wt motor oil okay?
