Bolt(680) C150trx 1999

If you have already checked and refurbished (if necessary) the carburettor assembly, you should also check the fuel feed and the various lines, unions and filters that feed the carb; replacing degraded, cracked or corroding parts with new components where required.
Clean, correctly filtered fuel, is perhaps the most vital element for reliability - how many marine engines have failed (usually at the worst possible moment) through contaminated fuel? We would suggest a great many!
