1973 Mrecury 115hp

[Dale Price]

I just replaced a burned piston,and replaced all the piston rings. I also rebuilt al the carbs.<br />The problem I'm having is when we back in a test tank and get down on it it boggs and gas comes out of all the carbs from the float overflow hole.Low idle works great. motor runs great. all high speed jets are clear. If there is a expert Mercury Person out there, please email me anytime.<br />dpriceis@earthlink.net <br /><br /> Thanks, Dale Price

You need to change the needle and seats as well as the floats in the carbs.<br /><br />The problem should disappear after that.<br /><br />TMD
