I have a 1981 mer cruiser 228 305 motor. The trim is loud, and linkages are tight. I put oil on the linkages hoping they will work themselves out, but was wondering if there was anything to do about the trim. Also I was think about a winter project rebuilding the stern drive. I have the original stern drive on the boat not sure if its every been rebuilt before was wondering if I should think about going new. If I was to go new could I hook up with my 1981 merc motor?
