Compression on older 150hp evinrude

[bksah2]

Hi All Anyone know what the compression should be on a older 1986 150hp evinrude ..I know on most outboards the comp. should be over 100 psi and even on all cycls.. But I am getting conflicting info on theses motors ..Some posts on google state that the big old motors were only rated at 80-90psi and some other post state 110-120..they state some as loopers and some as crossflows I think,,, which I have no idea what either are..THANKS
