I recently replaced my 1983 evinrude 50 with a 1992 johnson 48 due to lower unit problems. My evinrude 50 pushed my 20ft pontoon @21 mph. My 48 pushes it at 12 mph. I was wondering if the 1983 evinrude 50 is that much more powerful than the newer johnson 48? Johnson 48 is running with the prop that was pulled from the 50. The 48 has clean carbs and starts and runs awesome other than being slow.
