This was after I went to a couple of more well known dealers in the area. They told me that they don't work on older engines and wanted me to invest in a new one. At the Boat Shak, "Bill", the owner, replaced some parts and seal screws that were installed incorrectly by another repair shop, did a compression test, replaced my throttle cable, etc. and now the motor runs great. His years of experience show themselves in his competent service. The Boat Shak is the place to go for boat repairs in the Sandhills.
