Actually, Briguy is wrong. According to Zuke here:
http://www.suzukimarine.com/sr06/df1..._and_specs.php
25" Shaft DF140 is 420 lbs.
25" Shaft DF150/DF175 are 474 lbs
25" Shaft DF200 is 580 lbs
Whereas according to Bomb, here:
http://www.evinrude.com/en-US/Engine...ications/S200/
25" Shaft E-tec 150/175/200 are 427 lbs !!!!!
That means you can get a 200 E-tec and it only weighs 7 lbs more than the Zuke 140.
Having not owned either I cannot make any comment on reliability or maintenance.
