    I needed a new outboard engine last September as the old 2T Mariner was suffering from old age. Ideally the new one was required within 4 hours to catch the tide. Wills quoted a very competitive price compared to internet advertisers for a new 5hp Mercury 4T outboard and also gave a very fair trade-in price for the old engine. Wills also undertook to have the new engine prepared and ready for use in the time frame. Overall Will Marine provided a very good service and proved to me that buying locally can certainly be the best option.
