Hi I have a ChrisCraft 1988 Aerosport with two 350 chevys and when I put my starboard motor in reverse its making a grinding noise, any ideas? (my mechanic thinks the bolt may have come lose in the housing). I read in another post that bad spark plugs could cause this?

Thanks in advance.
I met a really amazing guy who has a 90 foot boat and he came out and listened to my boat as I put it in gear and he said it sounds fine, I think it was because I had the hatches opened, but now it just sounds like the linkage engaging. He did say on the starboard motor the timing was a bit off as the motor would shut off when it was idling. He suggested I put one of those magnetic dip sticks in the transmission that will collect anything in there.
