Sea Jay 4.88 Avenger Sports with 75hp Yamaha

We call it the ‘Sea Jay Curse’ at Fishing Monthly. The Bay flattens out and the wind stops whenever we go to test a Sea Jay. If you’re an angler, then you may think this is a good thing, but it doesn’t let you get a feel for the hull in the rough.

There’s no denying that Bundaberg’s Sea Jay make a great-looking boat. Every time we upload a video-test to social media, there are plenty of people commenting that a Sea Jay is their dream rig. Luckily, the boats are built to last and perform their duties nicely.

The 4.88 Avenger Sports that Garry Fitzgerald turned up with at the boat ramp at Cleveland was no exception. Garry is the National Sales Manager on the brand and had borrowed the rig from long time Sea Jay dealer, Stones Corner Marine in Brisbane.

As it was fitted with one of the new F75 Yamahas, Willie Lee from Yamaha was there, too. Yamaha is proud of this motor (which is based on the F90) and Yamaha is always keen to see how their product performs on local hulls. And as a spectator commented as we were preparing the rig for launch, it looks “mint!”

Yes, the Avenger 4.88 will turn heads at the ramp, with its Yamaha paint matching, wide beam and shallow draft, it’ll be easy for the family to get on board, too.
Wide gunwales all round offer plenty of places to mount rod holders.
The small casting deck up front has a couple of storage compartments. Anglers fitting a bow-mounted electric will often mount the batteries here to reduce bow lift.

The Avenger hulls have a reputation for being beamy – you can see just how beamy they are in this pic from above.
The helm is comfortable and you can rest your arm on the gunwale while using the throttle.
With several seat-mounting options, you can set up the seats to suit the sort of fishing that you’re likely to do. Half-pockets at the rear of the aft of the casting deck offer some gear storage.
We love that there’s a small, waterproof compartment for your valuables. Also, there’s plenty of space to bracket mount a large fish finder. The grab rails complete this practical console.
You want plenty of flat, open deck space? You’ve come to the right place!
With a full height transom and motor well, there’s room to fish in the port and starboard transom corners.
Here’s the best of both worlds – an anchor box and an electric motor plate. Great for the bait fisher and lure caster.
Yamaha’s F75 is substantially heavier than their F70 (by around 44kg), but offers nearly double the displacement (1.8L versus 1.0L) and plenty of torque. The 2.30m beam holds the motor easily and it sits under the transom’s maximum weight threshold by 7kg.
The south east corner of Peel Island is a pretty part of Moreton Bay and offers a variety for the angler and the boat tester.

Although there’s only 5hp difference between the 70 and 75hp Yamahas, there’s nearly 50kg weight difference. The 70 is a 1.0L outboard and the 75 is the same platform as the F90 and has a 1.8L capacity.

With a less beamy boat, this may be a problem, but the 2.3m of width at the back of the Sea Jay holds the weight with ease. And the 90hp version would also legally fit on this hull.

Apart from the weight, the main difference between the two motors is torque in the mid-range. Some dealers will tell you that “there’s no replacement for displacement”, and the capacity of this engine can definitely be felt as the hammers go down.

Having virtually no weight in the boat apart from some safety gear and the occupants (i.e., no trolling motor, batteries or fishing tackle) also helped this rig jump up and out of the hole. In fact, I think that some extra weight in the hull would make it more stable at rest, as it was so light that it would rock from chine to chine at rest.

Nothing that a full tank of fuel and a MotorGuide wouldn’t sort out.

Of course, the 75 Yamaha was super efficient, getting over 3km/L of fuel at a cruising speed of 43km/h at 4000 rpm.

From a fishing point of view, the world is your oyster with the Adrenaline hull – there’s mountains of space inside it to accommodate three anglers comfortably, or a boat load of camping gear. It’d definitely be a great ‘weekend’ boat to get to remote campsites and tote all of the gear that you need to make the trip comfortable.

Available through the Sea Jay dealer network, the company has a reputation of being easy to deal with when ordering options and customisation for your rig. They’re big enough to build you the boat you want quickly and small enough to still listen to their customers.

Sea Jay can supply trailers for all of their boats, however this hull was cradled on a Redco from Stones Corner.

As tested, the package we took for a run weighed in at $34,500, although BMT packages start from the low $30Ks.
