I am going to take my In-Laws boat out to the lake but before I do I really want to make sure I don't get stuck out in the middle of the lake. The OB is from all that I can tell is a 1977 Chrysler 105HP Model 1209HG S/N 5973. Checking all the posts was helpfull. I have some really basic and rookie questions regarding this motor. It finally started on the muff with a lot of help from starting fluid in the carbs. Out for a test run on the water and motor ran good but would stutter at full throtle. We figured that we may be getting air leaks on the fuel line. I am planning on changing the plugs, since they are older than who knows. Will replace the gas line and bulb from tank since there is a minor leak. I need to know what the proper fuel and oil mixture is since father in-law just looked at the mixture rate on the Marine Oil container. I could not find any difinative posts that really answered this particular model. I also need to know what type of lower case oil to use. I asked the father in law if he ever winterized the motor and he said there really was no need since all the water drained out of the motor. I now know that he may have done more damage than he realized. I would like to enjoy time out on the water but also do not want to get stuck on the water. Any assistance would be greatly appreciated for DaRookie.
