Engine mount

[marky48170]

1983 Chris Craft scorpion 169 120 hp mercruiser w/alpha 1. I was in the process of winterizing and noticed the front engine mount wasn't sitting on the (looks like a washer) and the top fiber washers under the locknut could spin. Is this normal? Still learning about boats so fire away !!

The front mount should not be loose. Before you tighten it down, remove the drive and check the alignment, if it's good then tighten down and recheck.

The drive is removed. So if I tighen it down I will have to realign?

Not necessarily, Need an engine alignment bar to put where the drive was.

I have the same issue. I started to winterize my boat and noticed the engine mount nut on the port side was loose and backed off about 1/4". Starboard engine mount was loose also but still in contact with lock washer. I get the alignment check done every year since I owned the boat (it is a 2011) and I put about 50 hours/year on it. Is it common for these eng mnt nuts to loosen or is it a case of poor service (Mech not tightening)?
Bigger concern is if this resulted in additional wear or damage to engine coupler and/or Gimbal bearing ? Can this be determined by pulling the drive and inspect these parts?

I have a 2011 Four Winns H180 LE Mercruiser 4.3L Alpha 1 Gen2
