Just got her up and running again. The Yamaha 115 blew while I was on the way back to the boat ramp on the Potomac a year and a half ago. The bottom rod bearing gave out and caused much damage. I had the local dealer put a 90 hp E-tech on it. Just went out and tested it today. Ran it 16 miles. It holds 39 mph at 5500 rpm. The old motor ran 47 mph at about 5400 rpm. I sure like that boat.
