Mercury Optimax 115 problem
I have a 2007 mercury optimax 115. For the most part it runs great! I have a very intermittent problem tho. Sometimes when I start the motor it runs rough and doesn’t seem to be firing on all cylinders. It just Boggs down and it slow to get on plane and then if I bring the throttle back down it dies and is hard to get started again. I can let the motor sit for a few minutes and then start it back up and it runs great the rest of the day. Any help or advice would be greatly appreciated. The whole fuel system has been completely redone, new coils and spark plugs.
