2007 DF 250

Looking at a used DF250 and am wondering how reliable and fuel efficient these motors are. Would be replacing a 150 Etec on a 2100 lund Baron. Any advice appreciated. Thanks

Generally they are a good reliable engine.

But at 16 years old, each individual one would need a thorough inspection and testing before purchase.

At the very least:
- drop the leg and check the gearbox oil. Legs can get stuck and you dont want to buy one unless the leg comes off.

- get a download from the ecu. A Suzuki mechanic familiar with the SDS diagnostic system can do this, and review the info including the history of fault codes and service resets to see if any obvious issues are shown. It will also show the number of hours run in each 1000 rpm band between idle and full rpm. This will give you a good idea of how the engine has been run. You want to see some rpm hours between 5000-6000 as an indication that it has been propped correctly.

- get the usual compression and other checks done.

Thanks Moonlighter, the leg was recently resealed and water pump changed so shouldn't be an issue, only ever run in fresh water, guy had a low oil pressure alarm so shut it down and turned out to be a hairline crack in the oil pump which I don't know if this is common or not on these motors. He says he changed the oil every 50 hrs and had it tested for contamination. Only damage found was thrust bearing and valve guides. All repaired at engine shop with receipts and documentation to prove the work. Rpm profile looks pretty good, has some time above 6000 rpm with majority at 0-1000 then 3000-4000. Definitely will check compression. He has the SDS diagnostics to go with the motor as well as all gauges and control box and hydraulic steering. Asking $12500 CAD. 16 year old engine but hasn't been sitting just low hrs per year usage.
