i have a 1995 150 johnson and was wondering what the compression specs ive heard that it is one of the year modles with a lower compression. it has about 91 to 92 psi on cylenders 4 and 6 and the rest have about 96 psi. these readings was took to day after getting back from fishing so engine eas still a little warm to the tuch

I'm not sure what the specs would have been new for that model.

But the main concern is usually that you have even numbers or at least within 10% or so of one another.

So you would seem to be in good shape. :)
