I have a 5.oL EFI Merc and am trying to change the oil. BUT, the
previous owner tightened the oil filter beyond tight. In fact, I broke
one filter clamp already, and purchased a second clamp and am to the
point that I am bending the handle trying to loosen this filter. I
have never had a problem like this and am worried about really doing
some damage. Any suggestions other than taking it to my local dealer?
