I have a 1987 85hp Force.. Problem is I took the flywheel off to replace the trigger, dont remember there being a washer (bought it used) but the flyweel looks like it had a washer on it. Can you guys tell me if there is a washer under the nut?? I looked at the merc parts list, picture doesn't show one but there is a washer in the parts list but it's# is not shown on the picture..
