Hey guys. I figured making a new thread would be best. I have a 1996 90HP evinrude. Just replaced the two coils and new spark plugs. When I first gun the throttle it goes up to around 4500RPM and sounds great, holds that for about 5-8 seconds then bogs down to 4000RPM and further bogs down to 3000RPM. If I pull the throttle back it surges like it wants to go. If I then bf o full throttle it goes back to 4500 briefly then bogs down again.

I am Stumped. To me this feels like a fuel delivery issue. When it rips at 4500RPM it sounds fantastic. I just put a fresh tank of 50:1 with premium in it incase the gas was the problem.

Any thoughts?
