There are a number of things to look for when shopping
for a boat, and especially when it comes time to evaluate a diesel.
If you're comfortable around engines and a knucklebuster by choice, you'll have no difficulties with the 4-107. If you're at the other end of the spectrum, and you've indicated that you've never owned a diesel before, I suggest a thorough survey
of the auxiliary, along with a thorough survey
of the boat by someone certified to provide that service. Most towns through out the world stock some Perkins parts. Heck, they were even used for a few Series I and II Land Rovers.
I just completed a rebuild
of my Westerbeke 30 (VERY similar to the 107 and 108 Perkins block). Yes, many parts are interchangeable. This is basically a British engine, and the parts are priced a bit on the high side for my blood, but anything labeled "Marine" is going to carry a health
You did not indicate if the engine had many hours on the Hobbs meter. A low hour engine in a boat of this age could suggest that it wasn't run enough and lubricated regularly. A high Hobbs meter reading you might think would be a bad indicator, but I conjecture that it is actually a good thing. A high reading would suggest that the boat was run regularly, and that there's little chance that corrosion
set-in, in places like the water lift muffler
manifold. What condition is the water
pump">Raw Water Pump Impeller? How are the hoses and belts? Is the engine clean looking and appear to be well maintained? Is the gasket material soft and pliable? Are there maintenance records for the Perkins? Are there any noticeable fuel
and or leaks/ordors or stains in the engine room?
This are the sorts of questions I'd be looking to ask myself when evaluating a boat for purchase
Best of Luck and happy hunting!

PS: Pictures of the Westerbeke 30 rebuild
are on my flickr page. Go to flickr dot com, then search for my name followed by forward slash photos, the another forward slash and my name spelled out in one word. A search for "Westerbeke 30 rebuild" may get you there too.

On this site, some owners have spoken about the Perkins 4-108
as being "bulletproof" and having a wide availability of parts, but what about the 4-107? (Some of the info I googled up on the net in general seems to indicate that the 4-107 and 4-108 are close to being the same model.)
Any warnings or endorsements for the Perkins 4-107?
