I have a 30 hp Mercury 4 cycle with 200 hours on it. I'm only getting 3200 rpm under load. It will idle fine at higher rpms. the water coming out of the pee hole is the same temp as the lake. I changed the impeller. The old one looked fine. Still cold coming out. Any ideas and guidance would be...
I have a 94 25 hp 2 stroke that quit running. I rebuilt the carb. Starts up and idles for 20 to 30 seconds then revs up and dies. Anyone have this problem or ideas?
