Hi All. I'm in need of your kind assistance again please.
I have a kind of new to me 1991 200hp mariner. Serial number 0D068540 While getting to know the motor I have come across a few things that tell me that it might have been fiddled with before i got it, so i am nervous that certain things may not be as they should.
i have recently moved house where i was operating the boat at around 5700 to 6000 ft above sea level. I will now be operating between sea level and 2000 ft and believe that a change of jets may be needed to prevent me from frying the motor.
i recently rebuilt the carbs at my previous elevation. They appear to be wmc 1,2 or 3 carbs. The main jets were 0.68. Across all three carbs. I cannot recall what the idle, air and intermediate jets were.
can anyone please tell me what the correct jet sizes are for this motor at the altitude i will be operating at?
thank you kindly
