I currently have an old 16ft Larson Shark trihull boat. It originally had a 1969 Johnson 85hp motor on it. That motor is no good so I bought what I believed to be a 1981 Johnson 90hp motor to replace it. Well after I bought it I was looking up the serial number to find the proper replacement impeller and low and behold the motor is a 1980 Johnson 115hp with the wrong decals. According to the Nada guide it weighs 305lbs. Unfortunately the nada guide only goes back to 1974. What is the weight difference between the 1969 85hp and the 1980 115hp? My transom is in pretty good condition( I have tested it and drilled test holes to check for rot in the wood). I do not want to break the transom trying to use this motor. Thanks for any help or suggestions!
