Nice choice on the Yamaha 50's!
EFI instead of carburetors (easier starting, better mileage, cleaner running, all the new electronic monitoring and control)
996 cc per engine instead of 808 (more torque, less relative stress on engine)
four cylinders per engine instead of three (smoother, less vibration)
same 996 cc block develops 60 hp in "tuned up" model (means this one is working less hard, will last longer)
2 engines at 237 lbs each = 474 lbs, a bit heavier than 2 Hondas at 201 each = 402, but still within limits easily, as
Honda 90 = 373 lbs, and Honda BF8L = 79 lbs, and Total = 452 lbs.
and
Yamaha 90 = 369 lbs, and Yamaha F8L = 83 lbs, and Total = 452 lbs.
and
2 Suzuki DF 40s or DF50s = 238 lbs each, and Total = 476 lbs.
and
Suzuki DF90 = 416 lbs, and Suzuki DF 9.9 = 107 lbs, and Total = 523 lbs!
Plus you have 100 horses instead of 80!!! Now your chances of planning on one engine without the other one are much greater! Have you tried this, Gary?
Much more to consider, of course, but the preliminary comparative numbers look very good! Keep us posted on your experiences with your new Yami-Rams!!! Joe.
