2007 etec 115 sounds louder then I remember

Hey Guy's sorry to keep pestering you for answers and insight.

My motor doesn't sound right to me, seems  louder then I remember it being last yr. I replaced thermostats, filters, vapor seperator filter, impeller, and plugs but just doesn't purr, would a bad injector make that happen and I'm not really sure how to test them. I thought about unplugging them 1 at a time and seeing if there was a difference in sound. Also want to pull the plugs and see if they are burnning right or not. Boats still in the water hoping to try something there before pulling it. 

Again as always I appreciate your time and knowledge

Unless it is a loud clang, rattle, or clunk,  sounds are subjective.

 

If you hear the motor sound slightly different around 4000 rpm and higher, it may be when the exhaust tuning valve moves from  its low speed to high speed position. That is normal for all Evinrude E-TEC V4 engines.

 

Make sure your motor turns close to 5600-5800 rpm at full throttle with an average load of people, fuel, and gear.
