Kent Island Marine provides state of the art marine and automotive FUEL INJECTOR SERVICE and CLEANING. I have parts in stock for most Yamaha, Suzuki, Mercury, Honda, Mercruiser, Crusader, Volvo, automotive and most top feed injectors. I even service Yamaha HPDI and Mercury OPTIMAX air and fuel injectors.

I have been your neighbor here on Kent Island for over 40 years and have always enjoyed my clients and being part of our growing boating community. I look forward to serving my clients with an honest, strong work ethic and old fashioned approach to your boat maintenance and repairs.
