About to try to have my original windlass refurbished.  The breaker on the motor trips under the slightest load.  Luckily my electrician loves this kind of stuff!  Not sure if it is the motor or the gears, but I'm betting it is the motor.  Even my undersized ground tackle is a bear to retrieve by hand!

Same problem on JH3TE.  I have an autoprop too.  Got worse and a injector pump was diagnosed and rebuilt at 3000 hours (2011).  Problem was solved and still working well at 6000 hours.

As far what insurers may require, as we are on our first year of outside the US cruising we did an extensive amount of research last year on insurers. I didn't find any that  required a standing rigging replacement. But most if not all required a recent (two years) survey and then an additional survey every following 5 years. Just my recent experience, good luck

If the main dc isolator from the batteries is switched off, the invertor should be completely off.
The only items I know of which can still have dc power bypassing the battery isolator are
bowthruster, anchor windlass, chart table lighting and bilge pumps. There may be some leakage in these. Some bilge pump level switches are electronic with no moving parts and thes cause a continuous load. Best way to track down source is to disconnect wiring one circuit at a time. The accuracy of your measurement equipment may be a bit off at this power level and the load is lower than you think.

If you are exploring different props, you might look at the Autoprop. It is a prop that automatically adjusts the pitch and when the engine is shut off, the blades feather. We installed one a year ago on our 44 and have been very happy. At 2350 rpms we burn 1 gal per hour and cruise in flat water at 7.5 knots, or we can reduce rpms to 1900 and cruse at 6.8 knots, with a reduction in fuel. It is very good when motorsailing in light winds 4 to 8 knots off the beam, we will then cruise at slightly over 8 knots. Essentially it adjusts the pitch of the blades to utilize the available horsepower, whereas fixed pitch props are only optimal at one rpm. It is slower to accelerate in forward or reverse because you need some flow over the prop to get it to automatically pitch the blades, so it isn't as good in reverse as a MaxProp.

Concerning engine temperatures, we just flushed the raw water cooling system using Barnacle Buster (instructions on their website) and it made a major difference. Before the engine temperature would rise significantly after 3 to 4 minutes at 2800 rpms, but after cleaning there is just a small increase in temperature.
