I have had this boat since april. Just started working on it again and I picked up a compression tester from a friend. #1= 25 #2= 45 #3= 25. I know the compression is really low but not sure why. Is it likely all 3 sets of rings are stuck? I took the head off and sprayed penetrating oil in on top of the pistons and let it soak awhile then put the head back on and i get the same readings. I have read that bad crank seals can cause poor compression, but what else is there that could make the compression this bad?
Thanks ahead for any help.
