Hello everyone,<br /><br />I wrote in a few weeks ago regarding this boat. At the time I had a problem with low power. I think I solved that problem by making sure that all 4 coils were properly grounded to the block. Now the problem is that ever since then the engine has been idling very fast (3000+ rpm) when in the driveway with the earmuffs on. I have now taken the carbs off 3 times to inspect and I am sure that there are no carb-related air leaks. I have also cleaned all the jets on the carb. They are all original jets and have not been changed out since the boat was running properly.<br /><br />I have tried adjusting the idle speed stop on the throttle arm linkage, but this has no affect on the carb throttle plates since there is already a gap between the throttle cam and the carb roller. The carb throttle plates are definately closed and centered in the barrel. I guess my question is where do I check next? Will the RPMs go down when the boat is actually in the water and the exhaust has the extra backpressure?<br /><br />Any help is very much appreciated. My wife thinks this boat is a money pit and will never run right.
