Our previous boat had a Lehman 2712E that looked almost identical to the picture on the boat for sale
except that the coolant
tank was a bit different. They do seem pretty bullet proof if you change the oil
and filters regularly and keep the heat exchangers and impeller pump clean and in good order. They are very easy to work on although some parts
are supposed to be harder and harder to get. I could always find what I needed when I had the boat though. Some mechanics recommend having the oil
checked by a lab. You should always use a top notch coolant
. The elbows can corrode out over time so you should carefully inspect that. Ours had a Borg-Warner hydraulic transmission
and that was also virtually bullet proof.
