Hi All.
I have a 1988 mariner 200hp that has always ran fine/perfect until this last week. In this last week the performance has slowly deteriated. Harder to start, idle eratic and use to be 8 to 900 and now is 10-1100, sounds like it is missing a little and has an occasional cough, all the plugs look really wet, it is now very hard to get up on plane, really rough running when going slow in no wake zone. It even cut out on friday doing about 25mph and had to be restarted. It rev's up slow when not in gear:%.
Easy stuff I tried on the water.
I tried running off a portable tank to make sure it was not fuel and no change.
I tried new plugs and no change
I tried carb cleaner and no change
I opened up carb bowl screw to make sure each carb had fuel
I held my hand over each carb (choke) to make sure each one was sucking up gas.
I am pulling boat out next weekend. Any suggestions where to start first.
Thanks
