I have IMCO solid motor mounts on my boat. At the back of the engine there are two large bolts with large washers, each screwing downward. I don't know what you call these bolts, but they appear to be the rear mounts for the engine. I noticed that one of these bolts is loose enough for me to freely spin the washer. Should I tighten it, or will it adversely affect my alignment with the outdrive? Any insight would be greatly appreciated.

Thanks

GotTheFever,
The rear mount is not adjustable. Just retighten the bolt.

Thanks Candyman,
I'll break out the ratchet and torque it down.

If its a Bravo, I would check the drive alignment too. Every once in a while, the rubber in the rear mount (part of the flywheel cover) gives out and this lowers the rear of the engine. The loose bolt wouldnt indicate this by itself but I would check it to be sure
