Early Eighties Mercury 18hp.

Started out running good then after an hour or so trying to get up on plane it seemed like it was running on one cylinder. and almost stall. I got it running again it did the same thing. I was about to keep it running at an idle to get back to the launch. And does anyone nake the coil with a hole in it for mounting or is there a way to mount the coil with no hole in it. Last thought, could it be water in the gas??

Do you put a new water pump impeller in every 3 years ?
