When the dust settles on all the time spent including sourcing parts, if you did it without losing $75/hr, you're way ahead of the game.

I am already money ahead even if you add in the costs of bring the boat back. I only spend $5,200 getting the boat ready for the trip after the boat had little use for the previous 38 years.
I had to access the boats real condition. I am the third owner in 45 years. I bought the boat with 1,320 hours on the engines and 5 hours on a rebuilt genny. The boat had 1,320 hours since new. Last owner was a professional rig captain who kept the boat n fresh water and a covered slip. 23 years. The boat was filthy but mechanically maintained
I don't need to research things all that much and hunt down parts. Some examples. The previous owner said all of the fuel valves except one were froze up and would need replacing. He had replaced one after messing it up. I looked at them and quickly determined they were Teledyne gate valves. I emoved a handle, took a flat punch and a hammer and tapped the tumbler next to where the handle attaches. They are spring loaded and that frees them up instantly. I put the handle back on. Problem solved in 5 minutes per valve.
Another, previous owner sold the boat as not having stabilizers because to his knowledge, they had not worked in 38 years. I went on line for information, crickets, company out of business 25 years ago. No problem, go in the shop make new air lines, take valves and cylinders apart, walk to drawers and pick out seals that would work. scrap the old dryer and find a new coalescer in a bin and install that, clean out the air tanks service the compressors, free up the shafts, put it back together and fire it up. They worked fine all the way home. I took a guess at the operating pressures and the range of motion based on design. Will redesign them this winter with more up to date pneumatics and add electrics. For me, simple and straight forward. Out of pocket probably $200 because I what I have on the shelves.
One thing I really liked about the boat was the electronics were all way old and the electrical system has not been bastardized by every specialist making installations on the boat with goodies like running wires through limber holes.
Biggest problem is getting this body fixed or I will lose my labor.
Biggest oops was miscalculating the size of the cleaning job. Wax on/wax off does not work without a rotator cuff.
Bottom line here. Even with all my skills I could still lose this game.
