Which is why I've seen so many boats where the engine has at best had the head pulled, repairs completed, the hour meter reset and given the label rebuilt.
IMHO All boats sell, only the lack of exposure and/or too high a price prevents the sale.

|camaraderie||I would much prefer a rebuilt engine with low hours to an original engine with 5000 hours. New is even better and will add some value to the resale of a boat in comparison to other models with old, high mileage engines. A rebuild probably adds very little...but without one, the boat becomes impossible to sell.|

I wonder if the engine was the problem?
Having been recently looking for a boat to buy I can point out that the decision will effect the value of the boat.
The first thing I would like to point out is rebuilding the engine adds the least to the value of the boat. I think most buyers might prefer having the engine "rebuilt" rather than running rough but I added no value to the boat for having a rebuilt.
Unless it was clear the rebuild was done properly. I didn't see very many of those. A proper rebuild requires the engine to be removed from the engine bay. Otherwise it is just a repair, IMHO.
If you are removing the engine then be sure to clean and paint the engine bay. Replace or recondition everything you can so the expensive engine on which you've spent thousands of dollars has an engine bay that looks like the rebuild was done properly.
Putting even a brand new engine in a dirty old engine bay screams cheap and low quaility.
If it was a rebuild done by the owner it communicates the ability of that owner to do the work. If it was a rebuilt by a local mechanic then a dirty old engine bay will suggest this was a repair done on the cheap and will likely have created more problems than it solved.
I've seen more than one "rebuild" with a dirty engine bay, engine leaking oil, and many rusted parts. These are nothing but trouble, I took into account major engine repair or replacement would be required sooner rather than later.
The cheapest option is repair.
The engine may have to be removed for repair and might cost thousands but it is much more honest to say the engine was repaired rather than rebuilt even if you spent thousands. There is no requirement to say the engine had been repaired unless the person asks why the engine bay looks so good. Then the work becomes maintenance/repair and shows that the engine gets the work and mtce it needs. Be sure to blame the previous owner, . Repair seems to be a much more honest way to describe the work but I suspect many buyers would think rebuild just sounds better. So I guess it depends, who you are and how you are presenting the boat.
If considering a rebuild I would suggest buying a rebuilt engine and using your old engine to save the core charge. This is really the only proper way to get a good rebuilt engine. The local shop cannot compete with the cost or level of detail of a dedicated rebuild shop. You will also get a great warranty. Of course some local shops can (some are rebuild centers) but I'm saying most can't (although most will say they can).
Max value, and cost comes from upgrading to a newer, lighter, quieter, more fuel efficient engine. At the same time I would refurbish everything in the drive train. Unless the boat is really sweet I doubt you would recoup the costs in the resale so that is something you would do for yourself not for resale.
I decided to pass on most boats with rebuilds as there were enough IPs out there with orginal engines or newer engines.

Try engine trader - http://www.enginetrader.com
They had a 3gm for 3500 with core tradein. I haven't used their service but looks pretty reputable. Maybe it'll work for you.

I think I replied on this thread when you posted your last request, but I can't find the reply so maybe it didn't go through or is floating around in cyberspace. I had my 3GM30F rebuilt this year at about the same number of hours as yours. Cost was about $3800 for the rebuild but I also replaced the engine mounts which are about $120 each; it is a lot easier to do with the engine out and damn near impossible with it in the boat. A replacement Yanmar (different engine) is about $10,000 and a re-manufactured 3GM30 thru Mack Boring about $5400+freight+installation. Contact me if you want more info.

I also have a 3GM30
My suggestion is to find a good mechanic in your area. I noticed you are in Va. I am on the Chersapeake near Baltimore and know of some good people in Annapolis. Is that to far for you. I may be able to find some as far south as Solomons Island.
Most work on the engines such as rebulid of injectors etc are sent to Mac Boring ihorth Jersey. They may have a lead on someone in your area. The Yanmars are workhorses and will last forever when cared for and refurbished also. Do not give up on it unless necessary.
