We had Siebert Yacht Management oversee bottom painting and light fiberglass work for our BC37. Both jobs were completed to a high standard! Jay Siebert also performed cooler service on our Cummins engine and Onan generator along with replacing the cooling system components on the main engine and changing fluids and filters. All work was done to a very high standard! Jay even stayed until 9:30 at night to finish the job. Above and beyond service! Jay is a very competent mechanic and he takes great pride in his work!
