There is a big difference between “looks ready” and “ready for a day on the water”.

Winter storage can expose weak batteries, tired connections and small trailer or pump issues. Finding those at home is considerably nicer than finding them at the ramp.

That is where being a Boating & Outdoors stockist matters: the range and buying strength of a national network, backed by a local team.

Pop into Mercury Bay Marine before you head back onto the water around Whitianga.

Marine knowledge is built one launch, one fault and one fishing trip at a time.

That practical experience helps match gear to the boat, the job and the person using it - and gives you someone local to come back to when you need help.

We are proud to be part of Boating & Outdoors, bringing the wider network’s range and buying power together with local marine knowledge in Whitianga.

A perfect boat on an unprepared trailer is still not going boating.

Check the tyres and sidewalls, make sure the spare is aboard and inflated, and confirm the jack and wheel brace you carry actually suit the trailer. It is a much easier exercise in the driveway than on the shoulder of the road.

Check out our 7 point check to ensure your trailer is set for the season - https://boatingandoutdoors.co.nz/boat-trailer-maintenance-nz/

If something needs attention, call in and see our team, part of the Boating & Outdoors dealer network.

We spend plenty of time thinking about what can go wrong on the water. Sometimes the trip comes unstuck before the boat reaches it. A boat trailer deals with heavy loads, long periods sitting still, highway speeds and regular saltwater immersion. Spring boat trailer maintenance is your chance to fin...

Winter is very good at revealing which batteries were already getting tired.

Check charge, terminals and cables, and if the battery condition is uncertain, have it properly tested - particularly if it has already seen several seasons.

Before you compare screen sizes, think about who is going to make the gear work on your boat.

Talk through how you use the boat, what is already fitted and what you actually want the upgrade to do. That makes it easier to choose sensibly and get the installation and configuration right.

At Mercury Bay Marine, you are dealing with a local Boating & Outdoors stockist, so the national range is backed by local advice and after-sales support.

Kids ready. Snacks packed. Boat ready too?

If something needs replacing or a second look, come and see us – as part of the Boating & Outdoors network we have all the parts.

Check lifejackets still fit, test the battery and electronics, look over fuel lines, anchor gear and the bilge pump, check the trailer, then use the marine forecast before you head out.

ENGINE RE-POWER BEFORE & AFTER ⚡️
Another repower by Mercury Bay Marine

This very tidy Tristram came in with an older Evinrude 115hp two-stroke that had reached the stage where its owner was ready for an upgrade.

While she was with us, we gave the boat a bit of a freshen-up too, including new clears, seat- swivels, and canopy, before fitting a new Mercury 115hp CT FourStroke.

The result?
A new boat feels that looks great, performs better and has a very happy owner.
He reckons he’s now using around half the fuel he was using before -not a bad improvement!

A good example of how a repower can give a well-loved boat a whole new lease on life, without having to replace the boat you already know and love.

ENGINE REPOWER — BEFORE & AFTER ⚡️
(Another repower by Mercury Bay Marine)

BEFORE: 2017 200hp Yamaha FourStroke
AFTER: 🔥 250hp Mercury V8 FourStroke

The owner of this Stabicraft wanted more grunt and better hole shot -so we stepped it up to Mercury's 4.6L V8 250hp.

The extra horsepower is only part of the story.
The V8 delivers strong low-end torque and acceleration, giving this boat more punch getting up onto the plane, particularly when loaded up with people, fuel and gear.

And as part of the repower, the helm has had a pretty nice upgrade too -Mercury controls and digital engine display, plus these Mercury DTS engines also come with Active Trim - (an automatic trimming system), no more manual trimming!

More power.
More grunt.
Fresh setup.
