4 Stroke Weight vs. 2 Stroke on Bracket

I'm looking as yamaha's website and the 150 4 stroke is just 40 lbs. more that the same size 2 stroke model.

Am I missing something with respect to weight that they are not displaying on the specs sheet?

I was almost convinced that I had to go with 2 stroke just from reading posts, but if I can, i'd really like to go 4.

Mid 80's Mercury 2.4L 200hp is only 360lbs!! and they are pretty good on fuel.

you also have to realize how they weigh engines now, there has been a lot of discusion in several magazines comaring actual weight and advertised weight. Bass and Walleye magazine had an article a few years back that weighed each engine in a as installed running engine with all gear needed for it to operate. It created a lot of heat from the manufactures. For example on a Merc verado, its weighed without a prop(no big deal), gear lube(can't be that much), engine oil and filter(hears a few more pounds), zincs(adding a few more), power steering assembly(big verados only, but you have to have to run the engine, and it weighs a fair amount), so by the time your finsihed, you've added a few hundred pounds(maybe not that much), but you see the point I'm making, on the old 2 strokes, all you added was prop and 2 stroke oil to the weight, so comparing newer engines to older ones can be missleading. From what I remember, the magazine weighed a 250 Yamaha, 250 Suzuki, 250 Verado, and a 250 Honda, all four strokes(some reason they didn't have e-tecs, HPDI's or Opti's in the article, may have been a later issue), all as installed weight to be operational including controlls and any standard item needed to operate the engine. I don't remeber the actual weights, but they all ended up being close to 200 lbs heavier installed, I think the merc was even heavier stripped down than advertised. So when you are comparing weights, just remeber to compare apples to apples
