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.
