The performance of the GTD 200 has to be tempered by the high sound level produced by the Evinrude G2 200 outboard, which was always present as unpleasant background noise. Note the 8-decibel difference at cruising speed. That’s huge. And the Evinrude also passed high-frequency vibration through the sole, which we did not feel in the sterndrive-powered boat. My personal experience tells me this is an Evinrude problem, not an outboard problem. A Mercury or Yamaha four-stroke outboard will likely be even quieter than the sterndrive. The Evinrude G2 platform does have its virtues. We love the onboard oil reservoir and the slick integrated power steering, the clean rigging, and the motor’s ability to “self-winterize.” The Evinrude 200 is also the most expensive engine option, with a base price of $50,700. The Mercury Verado 200 ($46,267) and Yamaha F200 ($44,467) undercut that price significantly, though they may not match the on-plane performance of the spunky two-stroke Evinrude. The outboard choice offered by your Glastron dealer will depend on its brand affiliation. The MerCruiser 4.5L 250 is smooth and quiet, and produces delightful midrange power. At $45,033, it also has a lower base price than any of the 200 hp outboards.
