(I am guessing it would be the same for each motor.)
I am looking at a rebuilt one with 115 psi across all cyls. and another
at 107-110 across all cyls.
Thanks....
I have read a number of threads re: interpreting compression readings and I get that
normally > 100 psi and within 10% on all cyls is the rule of thumb.
My question is, (all things being equal), if we are talking about the same two stroke outboard motor (make and hp), compression tester...
First time poster - here goes.
