Re: 2002 df140
The DF140 is a great engine, Boston, but might fall a bit short of the performance you are used to.
For its 140HP, the DF140 is pretty small displacement and it needs to rev to 6,000 (+) to make all of it. Because it weighs only 410lb it is a great engine for smaller boats that are rated for that power. For heavier boats rated at 150+ it seems anemic at less than WOT.
My guess is that you would be much happier with a "big block" Suzi DF in 150 or 175. LOTS of torque there.
On the other hand, if you are offered a good deal on a DF140 and don't lust for thrust it is a smooth, quiet, user friendly, economical and dependable engine.
