366 lb for a 2000 model year. The F75, F90 and F100 are pretty much the same thing. My guess is that cams are the difference? The F100 is no longer made. Certain Mercury motors used the F75/90 Yamaha engine. The F100 is known for lots of revs, not a lot of midrange. Not sure on the F75 or F90, but my guess would be that they are similar, or maybe a bit better midrange and a touch less top end? Fr. Frank knows.

The nice thing about the Yamaha is that the corrosion protection is good. It unbolts fine after 12 years and 700 hours.
