Mercury Classic 50 (45 hp) 1998
I have a 1988 Mercury Classic 50 (45 hp) 4 cylinder outboard and I have just
bought the Mercury Shop Manual for this unit. The manual is quite good but as I am new to outboard mtc. I have a hew questions for the experts: 1. In my sailing days I had a 6hp Johnson which had a thermostat but I cannot find where this is located on the Mercury. Does anyone know if this unit has one and where it is located. 2. I would like to check the compression but am concerned about damaging the electronics. Is it required to disable the spark, if so how. Manual does not say. 3. How does one adjust the linkage between the upper/lower carb to be sure they open in sync. Once again manual does not say. 4. How would I connect a tach and temp sensor. Is it possible? The local marine store has a box full of used tachs and I would like to put one in if practical. 5. The engine runs rough but a quick pull off of the top carb indicated improper float setting causing overflow on to bottom carb. I quickly did a tweak and overflow has stopped but it idles rough so I assume I need to pull off fuel system, clean, adjust and re-try. Any suggestions, tips would be appreciated. Any other advice would be appreciated. I know some do not seem to be Merc fans but I admit I like the look and it seems just to need some tinkering. A little like an MG, Triumph or other British sports car. TIA |
