[QUOTE="SAABologist, post: 490810, member: 31667"] Problem solved. The 40hp Mariner (model 40EL) ran better than ever today. Set a new speed record and zero hiccups. I guess I should have known, but it was dirty carburetors. I can't rule out the plugs because they were old and dirty and grimy. I changed them at the same time. But considering that it runs so much smoother and higher top end, I think it wasn't getting good flow from one or both carburetors. It was easier to take apart and clean these carburetors than any I have done on my 15hp mercury and 8 hp Evinrude. It's a quick and easy job on this 40hp. Thanks for taking time to point me in the right direction. Happy boating, [/QUOTE]
