Hello all, I am new here and I am looking at buying either a 1984 bayliner cierra with a volvo penta v4(thats how he stated it) or a 1985 bayliner capri with the volvo penta 2.1L... I was wondering what should the compression be on these motors, as i am going to check them out before i decide on what one.... Also is there anything to look for when checking them out that is a common problem? Thanks and I am sure I'll be posting mroe.

What is the model number of the engine?
If it's an AQ125A or B, you should see 145 to 175

OK thanks, I do not know the model number yet, so a min of 145? and how much difference in between cylinders is ok? I heard 10% so 15ish psi difference?
