They were always available to answer questions and kept me well informed. Their prices are comparable to other places in greater Newburyport.

Great marine mechanic! I had a quirky problem with my 25hp Evinrude Etec.

For a small job Jeff went above and beyond to find the problem and fix it then submitted it to Evinrude for the warranty claim. All this and I didn't even buy the motor from him originally. This is a business with very high integrity. A breath of fresh air after seeing what the competition does.

HELLO Yelpers! There…read moreis nothing like being out on the water, enjoying the sun and beaches of the north coast. My father now owns this company after a ten year slow overtaking of the business. The land was littered with old left over boats that had been abandoned by boat owners who just didn't want to keep up with there boat and left them to rot. After years of pain staking labor, the yard is now clean. The service of the crew that works at Tech Performance is excellent. I spent 2 years working as general labor / marketing / advertising, and light maintenance. In that time I was able to experience how hard this company works to get customers out on the water. The first big push for boating is Monday, May 25, 2015, this means more then half of all boaters are trying to get there boat ready for the season by that date. If you want to get out there and join in on the holiday, get your boat in line early! Stop in at the boat yard in March and get in line first. I personally spent hundreds of hours nights and weekends preparing boats for the holiday, We give 110% so people can be out on the water. The second big push is for the forth of July. Same story here, get on the maintenance list early. Tech Performance is full service which means they can do anything from an engine swap to repairing fiberglass. There are usually used boats in the yard for sale that people are upgrading from so ask if your in the market. Have a great day and happy boating.
