Cylinder compression on 25hp

[Bryan]

Trying to decide what do do with an older 25 hp 2stroke.

Does anyone know what the compression in psi should be for that motor. (1989 25 SF)

Also anyone anyone aware of any specific issues with that motor I need to be aware of?

Any Idea how reliable the Precision Blend injection unit is?

What oil:fuel ratio is used on that engine.

Thanks,

Bryan

The compression should be no more than 10% difference between cylinders. Not aware of any problems with the 25SF motors or the oil injection it's a very reliable motor and the oil pump is a varable ratio from 200:1 to 100:1.
