Fuel’s definitely front of mind at the moment. With global pressure on supply, it’s something every boatie is feeling, but it’s also an area where a bit of attention goes a long way. What we’re seeing in the workshop: A lot of engines aren’t running as efficiently as they could -often due to fuel quality or minor setup issues. 7 Simple tips that can help keep fuel costs down: Tip #1 Regular servicing is key. A well-maintained engine clean filters, fresh oil, and properly serviced injectors will always run more efficiently and burn less fuel. Tip #2 Keep your hull clean. Marine growth and grime create drag, forcing the engine to work harder and use more fuel. A clean hull can noticeably improve performance. Tip #3 Check your propeller . Damage, wear, or the wrong prop can reduce efficiency. Even small dings can affect fuel burn and overall performance. Tip #4 Trim and load matter. Running with the correct trim and avoiding unnecessary weight helps the boat plane easier and reduces strain on the engine. Tip #5 Use fresh, clean fuel. Old or contaminated fuel can impact performance and economy. Keeping tanks clean and using quality fuel helps maintain efficiency, Tip #6 Fuel storage. Especially important if you know your boat will be sitting for a while try using Mercury Fuel Stabiliser It keeps fuel fresh, protects the system, and helps engines run clean. Tip #7 Warm up and drive smoothly. Your actions have a direct effect on the fuel gauge. The way you load your boat alters its center of gravity, which affects its planing efficiency. Avoid hard acceleration from cold and try to maintain a steady cruising speed rather than constant throttle changes. Simple takeaway: It’s rarely one big fix- it’s usually a combination of small improvements that make a noticeable difference a well-looked-after boat not only performs better - it’ll save you money every time you head out.

Battery Talk. One of the Most Overlooked Parts of Boating There’s nothing worse than turning the key and hearing nothing back especially when the sea’s flat! Batteries are one of those parts of boating that usually don’t get much thought until they let you down. For boat owners around Whitianga and the wider Coromandel, marine batteries live a pretty hard life. Constant vibration, salt air, electronics running for long periods, and boats sitting unused between trips all take their toll over time. A lot of battery problems actually start long before the battery completely fails. Why Marine Batteries Can Fail So Often Unlike a car battery that gets regular use, marine batteries often sit for weeks at a time. During that period batteries slowly discharge, and if left low for too long they can begin to sulphate internally. Once that happens, performance and lifespan drop away quickly. Heat, vibration, and corrosion around terminals also play a big part, especially in marine environments. Quite often, what seems like a “sudden” battery failure has actually been building for months. The Importance of Proper Battery Charging One of the best things you can do for battery life is keep it properly charged with a quality marine battery charger or battery maintainer. A good charger helps: Maintain correct battery voltage Reduce sulphation while sitting unused Extend overall battery life Improve reliability when you need the boat most It’s a simple investment that can save a lot of frustration later on. At Mercury Bay Marine we stock battery chargers and charging systems suitable for: Marine batteries Jet-skis RVs and motorhomes Solar battery systems Century Marine Pro Batteries Our main battery range is Century Marine Pro, purpose-built for harsh marine conditions. These batteries are designed to handle: Constant vibration Rough water conditions Marine corrosion environments High starting loads and onboard accessories They provide strong starting power along with dependable performance for electronics and accessories onboard. For many local boat owners, reliability matters just as much as outright power. Free Battery Testing -at Mercury Bay Marine A battery can often seem fine right up until the moment it isn’t. That’s why we offer free battery testing at Mercury Bay Marine, and we test your battery as a part of your boat service every time. A quick test can give a much clearer picture of your battery’s health and help identify problems before they leave you stranded. Sometimes a battery simply needs charging properly. Other times it’s nearing the end of its life and it’s better to know before your next trip. No appointment needed for battery testing -Just drop in.

Free Battery Recycling ♻️ Old batteries shouldn’t just be left sitting around or thrown out with general waste. We can recycle your old battery safely and responsibly when replacing or upgrading your setup. *Free battery recycling excludes lithium batteries. At the end of the day.. Most battery problems are preventable with a bit of maintenance and regular checking. A healthy battery means your boat is ready when the weather lines up and the opportunity’s there. And around here, those good days are too valuable to miss.

Whether it’s a short run down to the ramp or a longer trip away, towing is something most people don’t think too much about... until something goes wrong. #1 Start at the hitch First thing to get right is your coupling and tow ball. There are a few common sizes. 1 7/8”, 50mm, and 2”. They are not interchangeable. If the coupling doesn’t match the tow ball properly, there’s a real risk of it coming off under load. Make sure it drops on cleanly, locks in properly, and is secured before you head off. Photos show an example of where you might find size stamps. Mercury Bay Marine also sell interchangeable towballs which definitely makes life easier. #2 Towbar tongue – worth a look A lot of modern tow bars have removable tongues. They’re convenient, but they can also hide corrosion. In coastal areas especially, we see these rust from the inside out. It’s worth pulling the tongue out every now and then, giving it a clean, and checking for any signs of rust or weakening. It’s an easy thing to overlook. Hidden rust ⸻ #3 Tyres – more than a quick glance Trailer tyres don’t get used as often as vehicle tyres, which can actually make them more prone to issues. Before heading away, check for: Bulging or uneven shape Cracks or splitting in the sidewalls Correct pressure Insure there is no wire poking out Longer trips will quickly show up any weaknesses. Damaged /perished tyre. ⸻ #4 If your boat trailers been sitting, take a short run If your boat hasn’t been used for a while, it’s worth doing a short tow locally first. If you hear a rumbling or growling noise from the trailer, that’s often wheel bearings starting to fail. It’s not something to ignore. When bearings go, they tend to go completely. Its also impoertnt not to over grease the bearing buddies as it can push the seal out from the back and let water inside. ⸻ #5 Rollers – a quick check Trailer rollers can sometimes rotate or flip around, especially after loading. Also damaged split pins or rusty washers can cause the rollers to fall off When that happens, they don’t support the hull properly and can create pressure points and damage or scratch your hull. It only takes a quick look before launching to make sure everything is sitting as it should. Roller has come off damaging hull ⸻ #6 Tie-downs – not just good practice Your boat should always be properly secured to the trailer. Not just for safety, but because it’s a legal requirement. At a minimum: A secure winch rope and safety chain at the bow Tie-down straps at the stern holding the boat firmly to the trailer Loose or missing tie-downs can lead to movement on the road, damage to the boat, and in some cases fines or liability if something goes wrong. It’s one of the simplest things to get right. Some tie down products we stock at Mercury Bay Marine ⸻ #7 Trailer security It’s also worth thinking about security when the boat’s not in use. A hitch lock, sensible parking, and even a wheel clamp for longer-term storage can make a big difference. Unfortunately, trailers are an easy target if left unsecured. ⸻ Final thought Like most things in boating, it comes back to the basics. A well-maintained trailer makes towing safer, easier, and a lot less stressful. It also means when the weather lines up and the opportunity’s there, you’re not held back by something that could have been sorted earlier. If you’re unsure about any part of your setup, or just want it checked over, bring it in to us at Mercury Bay Marine - We’re always happy to have a look.
