FAQ
Why won’t my boat start after sitting for a few months?
Old fuel, a flat battery, clogged filters or corroded electrical connections are all common causes. A thorough pre-season check up can prevent these issues and help avoid damage from dry starts.
Is it safe to do basic boat repairs myself?
Some basic maintenance can be DIY, like battery checks or flushing the engine. But for anything involving the fuel system, electrics or propulsion, it’s best to leave it to someone with marine qualifications and experience.
How do I know if my trailer brakes need replacing?
If your trailer pulls unevenly, makes noise when braking or feels sluggish when stopping, it’s time for a brake inspection. Regular servicing is key, especially for trailers used in saltwater.
