Between 500 lb to 638 lb depending on model
I found this spec sheet from Yamaha. http://www.yamaha-motor.com/outboard/products/subcatspecs/2/specs.aspx The specs are probably for the 2008 models, but you can probably assume the 2006 weight is between 225 and 250 lb.
500
1993 evinrude 60 hp weight is 250 lb.
The 1998 model, Yamaha 250 hp outboard, requires an NGK BR9HS-10 spark plug, gapped to .039 in.
how much does a 1992 70hp force motor weight
They told me 250 lb. when I shipped mine. I can tell you it is heavy! Craig
The dry weight of the Mercury outboard FourStroke 40 HP boat motor released in 2005 is approximately 250 pounds. Later versions of this motor are slightly lighter.
The dry weight of a 1999 model, 70 hp Johnson outboard is 250 lbs.
210 pounds
The Yamaha Raptor 250 has about a 17 horsepower motor. However, when you start modifying them they open up quite a bit.
The motor oil to use in a 1982 Yamaha 250 XT 4-stroke dirt bike is a 10-30 or 10-40 weight oil. Castrol GTX Motor Oil that is of this weight is the best oil to use in off road bikes, because it is a cleaner oil. It will not gum up the works of smaller engines like regular motor oil.
probably 250 kg
