4 stroke outboards

[Mr. Sandman]

hondas appear to be the heaviest of the 4 strokes.
I have been comparing new engines for possible re-power:
engine weight

yamaha 150 4 stroke 466#

Yamaha 150-200 2 stroke 475#

Suzuki 140 4 stroke 421#

Evinrude 150-175 2 stroke 405#

Honda 115/130 4 stroke 505#
Honda 200/225 4 stroke 600#

There was an interesting boating-review show on TV about a week ago. It was sponsered by mercury and they did a good comparison between their 4 stroke and 2 FI stroke 225. They had 2 identical boats (about 26' CC) with the same fuel and passenger load. The boats each had twin 225's. One was FI 2 strokes the other 225 4 strokes.
They compared measured noise level, fuel consumption and speed for the full range of RPM. They also measured acclereation.

I have to say I was disapointed in the results.

The noise level was only better at very low speeds
The fuel econ was not much better and at some speeds the 2 strokes were better.
The 4 strokes were 7 knots slower at WOT
The accleration was poorer for the 4 strokes.
The emmision levels were very good (both exceeded 06 requirements)

The conclusion from the reviewer was "it boils down to personal preference...both are good choices" Huh? I guess he did not want to offend the sponsor...

They did not mention cost...I think the 2 strokes are a much better bang for the buck at this point.

I just got a quote for twin 150 yamaha 4 strokes (which are about 60# heavier per engine then my curent 2 stroke 150's)...I am suffering from sticker shock. with all the crap ...gauges, install ect. I am looking at 32.7K + tax
For a frikkin pair of crap OBs . You could by a Cat diesel for less then that! This industry is out of control. They are simply not worth that.
