I have twin 454's 1991. Last seasons I was leaving my marina for the last day of fun for the season, when the motor stalled at low rpms exiting the slip. I did get the engine refired after some cranking, motor then ran fine. I was able to get on plane and rpms at wot were in the range. After returning to the slip I went to back in and the one motor dies again while being shifted in and out of reverse.
Unwinterized boat on Friday, motors start without much cranking, again while backing out of the storage marina to go to permanent slip the motor stalls again. Upon getting the motor refired black smoke came from the exhaust. Ran the boat about five miles all was well. Before entering my marina I played around with the motor going forward and reverse and no issue at all. I pulled into the marina and started to back into my slip and it stalled again. After tieing up I began to play around with the the motor.
It seems like the throttle when pulled all the way back and out of gear the idle drops to 400 rpm or lower. Is there a stop at the carb that could be broken or an adjustment to raise the idle on the carb? Why the balck smoke when refiring motor? (smoke does turn white after a few seconds after start up)
Thanks
