I have a '74 Evinrude 15, I just got to run this motor for the first time today. I have replaced the water pump housing and impeller. It starts easily, runs smoothly, no misses, but it just doesn't seem to have the "umph"....I have a '69 9.5 that runs stronger in my opinion. I do have a Solec manual, but decided to look here for suggestions before I dive in blind. Also, where should this engine expell water, shoot a stream out the side or "spray" out with the exhaust?<br />Thanks in advace.<br />DC in Missippi
