What should compression be on '71 60HP?

[craigvalk]

Any of you know what the compression should be on a '71 60ESL71C three cyl?<br />My Seloc manual does not seem to list the spec. I am guessing somewhere around 100 PSI, but if anyone can confirm that, thanks. Heading up the lake tonight and would like to run a test when I get there.<br /><br />Thanks<br />Craig

Around 100 would be good, but more importantly, even on all cylinders(+ or - 10%)

I measured it today. 145, 145, 135. I think it's in good shape, agreed?

Is #2 the low one??

#3 is the low one ( the bottom cylinder).
