Just a small quibble with your weight figures... My understanding is that the 25" shaft ETEC 150HO is a 433 lbs engine (dry weight). However, that figure does not include the external oil tank, rigging, or oil, which adds another 25-30 lbs to the "all-in" figure. Let's call it 460 lbs.
The 2.8L Yamaha SHO 150 25" shaft is a 489 lbs engine dry weight. We could add another 10 lbs or so for 5 quarts of crankcase oil to that figure, so right around 500 lbs. That yields a weight difference between the two engines of roughly 40 lbs -- a fair bit less than the "spec" weight numbers initially suggest.
JRP,
I think you forgot to add the weight of the "rigging" for the Yamaha?
If you add it for the E-Tec, then you should add it to the Yamaha, right?
Current motors listed online.
Yamaha F150XA = 491 pounds

E-Tec 150X = 418 pounds

Joe, I see you edited your post and added additional info concerning engine weights.
The dry weight of the ETEC 150HO 25" shaft engine is 433 lbs. The 418 lbs figure is for the 20" shaft engine. I realize that the Evinrude website repeats the same weight for the 25" shaft as it shows for the 20" shaft version, but that is a typographical error. The ETEC 150HO 20" and 25" shafts have the same weights as the ETEC 135HO 20" and 25" shafts, i.e. 418 and 433 lbs respectively. I am shopping these engines and confirmed the error with Evinrude.
I thought it appropriate to compare the ETEC 150 "HO" engine to the comparable Yamaha "high output" engine, the 4-stroke SHO 150. This is a slightly higher displacement engine than the standard F150, and weighs a bit less at 489 lbs.
