Compression test

[Rranger]

had a total block rebuild done a year ago on a 1998 200hp. New parts, crank turned. The shop ran it for 2 minutes after putting it back together. That's all it ran til a guy who wanted to buy it wanted a compression test done on it this weekend. So at the customers request before starting it the shop did a compression test, the range was cylinders 1thru 6, 1-150, 2-138, 3-145, 4-140, 5-136, 6-136.
My questions
1) should the engine have been warmed up first?
2) considering it's not broke in, are those reasonable numbers?

kinda strange that much difference on "total rebuild" but if all not bored with new pistons, rings and some just received a hone its can be expected.. hot or cold won't make very much difference despite what some say...jan, these cranks can't be "turned" as like a car motor.... there is only one id size bearing for 'em.. much debated repair on 'em is completely different process........

I am not yet a believer in " repaired " crankshafts for outboard motors.----Crankshafts are precision stuff and not easily repaired to " factory new " specs.

I won't use 'em either......
