Came here to get a generator part for the boat. I had talked to Raul on the phone and explained what I needed so when I got there I asked for him, he handed me the part and I went up front to pay. Very friendly staff. Holiday hours were posted on the door, so call ahead if you plan to stop in during the holidays. They close at 5pm on regular business days. HOWTOFINDTHEM Located inside the Harbor Towne Marina. The marina wraps around a center block of offices. Sun Power Diesel is located in the northwest corner of this block of offices. It may take some driving around in a circle or stopping to ask someone, but you will eventually find them!
