You will find that they screw people out of hundreds of dollars and not delivering any type of credible work, nor will they stand behind any of their mechanics. To many out of state visitors have been reamed at this shop. So do your homework on local marine shops before you tour the area lakes, just in case. This place is basically a chop shop for marine motors. Only deal with them if it's emergency situation and you have your checkbook. An estimate alone will cost $300 after they needlessly pump your boat with oil and the old "dirty plugs" trick.
