Early 4 strks, especially early 2000s had the idles leaned out to pass emissions. The idle Jets were extremely prone to plugging and being difficult to clean. They also were leaned out to pass Emissions and that will also cause a bog.
Stay away from the 75 Hp unless you have a light hull. The 70 hp is a much better all around motor. I also prefer the 86 and later as they are actually prop rated motors.
You need to pull the cover off as the Bendix is under it. The gear spinning freely is normal. The Bendix is attached to that gear also check the Bushing the gear shaft rdes in.
