Hi all i have a 2004 bayliner 175 with a 3.0 mercruiser and while winterizing the boat i noticed the motor mount appeared to have come loose. The part of the mount that is fastened to the floor. I began to retighten the bolts but noticed that only one became tight the other was begining to strip. This bolt is also the one on the left side of the motor or steering wheel side of the boat. My question is what exactly is this bolt, is it a lag screw into the fiberglass or is it a bolt that i can some how access to tighten? if its a lag screw what do you recommend i do to fix this problem? This bolt is also the side where to motor pulls up on.... Thanks for your time , Andrew
