Hello i have a 1977 mercury 1150 tower of power motor. This last weekend i went to the mountains and ran the boat no power The marina told me to re jet the carbs. I cant find a chart that tells me what jets I need to run at 5000 and 8000 feet. I also dont know where the best place to find jets for this year of motor. And last but not least how and where the jets are that need replaced. I was wondering if anyone who has changed them has a picture or directions on how to change the jets. Thanks Tony
