He's getting antsy to move forward so he doesn't miss the entire sailing season, which is why I thought maybe he could get in there himself and get enough pulled off the engine to figure out if it's a rebuild candidate. He's very methodical and, while he doesn't have diesel experience, I think he could follow the manual and label and organize everything clearly enough that a pro could take over for him if he decided to go the rebuild route.
PS I visited your blog and looked at some of the exploding neighbor pics. Lordy!
I'd pull it and strip the head and pan off - that will tell you if it's done something terminal like throwing a rod. If not then go further - main & rod caps & so forth until you find the problem. Then you can determine if it's suitable for rebuilding. Paying a pro to strip and examine it isn't very expensive - it doesn't take long after its out of the boat.
If it's not rebuildable, I'd get a replacement 107 (I have a Perkins 107 in my boat.) Those old lumps run forever if they are maintained and as you point out - they can be rebuilt for a fraction of the cost of a new replacement, not to mention the installation/conversion costs for new. A big plus is: think of all the spare parts he'll have.
A properly rebuilt and maintained 107 will probably outlive your friends children.
