I have a 1987 Johnson 50 HP (model J50TLCUD) and I think is time to spend a little time and money on it. I have owned it since it was new and it continues to run strong. I have never had any material work done on it in the last 19 years. I have decarbed it last year and did not see a lot of difference, which I think is good. I have the OEM service manual for it so I should be able to do most of the work myself. I do think that I should put in a new impeller. Other than that what would be recommended.<br /><br />Any suggests would be welcomed<br /><br />Thanks and have a good day.
