Outstanding product

The complete new Sterndrive installed easy. I worked at Air Canada as a mechanic, I have built and raced cars for years. The quality of the Sterndrive is outstanding. The machining is excellent. Very,very impressed. I have recommended your company to my friends that have boats. Thank you very much. Don Jones Winnipeg, Manitoba Canada
