4stroke

[THEFERMANATOR]

To add onto what spare posted for comparison.
The old 2 stroke merc 60 degree 135-200hp engines weighed in from 370-390lbs. I believe the 3.0l 200-250hp mercs were around 450-470lbs.
For johnson/evinrude, the old 85-140 cross flow engines weighed around 300-310lbs, the 120-140 loopers were around 380lbs iirc, and the 200/225hp were 450-470lbs.
Not sure on yamahas, but I believe they were very close tothe others for the most part, and suzuki was right thete with them at 470lbs for there v-6's, and low 300's for thefe inline 4 cylinder's.

These weights are for the carbed and basic efi engines, not the dfi's.
