I was in need of engine diagnostics on my 2005 I/o. Crystal Cove Service was recommended by a marine parts store. I will qualify that I'm a retired auto service mgr (45 years) which I didn't reveal initially. I brought my boat at the appointed time and Lloyd received me professionally and courteously. Lloyd went right down to the boat and did a complete diag. scan explaining the results found in the scan. He was right on. Fixed the problem with 1 sensor and boat runs great. The next day Lloyd made a follow-up call to ensure all was ok! Great way to do business! I will utilize this business in the future with no hesitation. Bill Olsson Lynn ,Ma.
