Marine diesel engines are pretty simple. That said, working on them can be difficult because most are crammed into the boat without good access. Most are rusted, old, difficult to see, touch, and get at. Then there are the parts: expensive, rare, and not easy to obtain. There are the mechanics: again, expensive, rare, and not easy to obtain
Do you usually have someone fix it in the water or pull it?
About how much does it cost to pull and reinstall an engine on 27 foot boats?
Once they are working are they reliable? Say I got a boat, got the engine working and took good care of it like I treat my truck are they good reliable engines that won't strand me in the channel or are older boat diesel's notorious for trouble.
Typical maintenance can be done with the engine installed. This includes things like water pump changes, fuel injector changes, exhaust, etc. If you need to remove the head, or change the transmission, or something like, it will completely depend on the particular installation.
IMHO, and engine that has been maintained and is in decent running condition will last a very long time and be very reliable. Provide clean fuel, run it at proper RPM and temperature, and it will go and go and go.
But I did buy a Cascade 29 with a really terrible neglected inboard and regretted that one time.
This is the real thing. Who is going to work on the engine? Again, IMHO, if you have to pay to get the engine going, you are probably going to end up unhappy. If you have the skills, time, and patience to work on the engine yourself, you can come out way ahead. But, without knowing a whole lot more, you are looking at a real crapshoot.
