The other day I was on a short bay cruise, and when I turned around and put it in idle forward, a grinding, scraping, metal-on-metal noise came from what seemed to be the starboard side about mid-ship. The noise would stop after a few seconds and all seemed fine. This continued thru docking, every time I put the boat in forward the noise would start and last a few seconds then stop. I don’t want to move the boat until I can figure out what it is and have a mechanic look at it. Any ideas of where to start troubling shooting and what to look at with something like this? Could it be the transmission, bearings, something in propeller shaft seals...? Any help or ideas appreciated.
