Greetings fellow boaters. I am a newbie. I recently purchased a 12 ft. fiberglass boat. I have medical issues with my heart. so reliability is a must. A fellow boater recommended either a Mercury, or Yamaha. You folks seem to know what you are talking about, and I could really use your help. I intend to lake and river fish. Any help would be greatly appreciated. Thanks in advance. I am chomping at the bit to drown some worms.
