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 have had 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? What do I look for to make sure the coupler and gimbal bearing are ok? As I see it under heavy acceleration (skiing) the engine torque would cause the enigine to lift off the mount ( because the port side nut was backed) off which would throw the alignment off.
Should confirming engine mount torque be part of the alignment process? I can see the mech pulling the drive, checking the alignment and if it checks OK, not doing anything to the engine mount nuts.
