100 psi to 140 psi.
What is the Mercury 3.5 Hp four stroke valve clearance?
The 2 stroke will be faster because of differences in Waite but more polluting be it oil mixed with fuel
What is the torque specs for Head bolts for 2003 Johnson 4 stroke 140 hp outboard boat engine
The 1989 model, 25 hp Mercury 2 stroke outboard, has a dry weight of 112 lbs.
140 hp
The 1997 Mercury 150 HP 2-stroke outboard motor typically weighs around 460 pounds. In comparison, the 1995 Mercury 135 HP 2-stroke outboard motor weighs approximately 400 pounds. Thus, the 150 HP model is about 60 pounds heavier than the 135 HP version.
For a 1979 2-stroke Mercury 140 hp engine, the recommended gas mixture is typically a 50:1 ratio of gasoline to 2-stroke oil. This means for every 50 parts of gasoline, you should add 1 part of the appropriate 2-stroke oil. It's essential to use high-quality oil designed for marine 2-stroke engines to ensure optimal performance and engine longevity. Always check the owner's manual for specific recommendations related to your engine model.
The dry weight of a 1994 model, 15 hp Mercury 2 stroke engine, is 71 lbs, for all models.
A 25 HP Mercury 4-stroke engine generally produces less power and is lighter than a 40 HP Mercury 2-stroke engine. The 2-stroke design typically offers more power for its size due to its different combustion process, while 4-stroke engines are usually heavier and more fuel-efficient. Therefore, the 40 HP 2-stroke would have greater power output and potentially a different weight profile compared to the 25 HP 4-stroke.
