Ideal compression on '95 Yamaha 90?

[ebsworj]

Hi I'm going to be looking at a motor to replace my blown Suzuki this week. I don't want to get burned again. (yes I did a compression test on the suzuki) <br /><br />What would a normal compression reading be on a 1995 90hp Yamaha? Anything else I can look for before buying? I'm not familer with Yamaha's. I'm hoping this will be the engine to last me!<br /><br />thanks guys

Depending on the guage and the technique one healthy cylinder could read anywhere from about 90 to 150psi, eb.<br /><br />What is important is how close they all are to each other. A span of 10psi or less would be ideal.
