speedster compression

  1. C

    1997 speedster compression results. Good or Bad?

    The boat had been sitting for two years and just bought it. with bad gas and oil in it i got 120psi and 125psi on the right engine and then 125 and 125 on the left engine. I really want to get out to the lake and will i be fine with this readings? i read if they arent more then 10percent apart...
