Stessco Albacore SC640 with Yamaha F200 is a silver bullet

Unloaded, this rig is quick off the mark and shows marvellous fuel economy for a boat powered by 200hp – up to 2.2km/L.

Over the years that we have been testing Stessco boats, it seems as though the Albacore line has evolved the furthest and fastest. From its factory on the northern side of Brisbane, Stessco has expanded the range of these plate aluminium boats to five models from 4.8m to 6.4m, and they’re customisable to a centre-console or a side-console variation.

On the test day we had a fairly special craft to ride in. It was destined for a coral farm in Western Australia. The 6.4m side console was fitted with a Yamaha F200 4-stroke outboard, and was a massive working space that could carry huge loads.

It’s a broad and sturdy bait station with a shelf underneath and out of the mess.
The support from the duckboard also acts as a grab rail.
We’re unsure why the coral farm needs a live bait tank, but there it is in the back starboard corner.
These hatches on the transom give access to the electrics and isolators.
Now this is a serious side console! 6.4m of workhorse that’s bound for a coral farm in Western Australia.
The kill tank runs across the boat rather than along the keel.
There’s another small access hatch at the bottom of the console.
There’s no denying that there’s a mountain of work space in the 640 SC, complete with a little luxury in the form of padded gunwales.
There’s a transom door on the port side.
Stesscos come with a serious set of boarding stairs at the transom.
There are some substantial side pockets for your commonly used items.
Can you imagine this rig full of compressors and live coral?
That’s a meaty console with a removable panel you can flush mount your electronics into.
The raised front casting deck gives you a large amount of storage underneath.

This Stessco finally has channels that direct water away from the hatch opening. Amen! This is potentially a dry storage area.
It goes without saying that the stability is pretty good. This boat is designed to have all sorts of compressors, product and work gear on board.
The electric motor plate is now standard on Albacore hulls.

If fact, I’m sure that the performance figures quoted in this article should come with a disclaimer – “boat tested empty” – because I think that in its working life it will never be as lightly loaded as when we tested it.

Maybe that’s why some of the performance figures were so sweet: economy of 2.2km/L at 41km/h and 3,500rpm is fantastic for a Yamaha F200 outboard. And it might also explain why Donovan Weeks looked like he was having so much fun running the boat back and forth during the video and photo runs. It looked like a rocket sled!

At wide open throttle and 6,000rpm it went 79km/h but the range halved – you got only 1.1km per litre of fuel burned – so as always, it’s a balance between economy and fun.

All of these figures were achieved with a Yamaha Reliance 17” stainless steel SDS propeller.

As expected, there’s a substantial (220L) fuel tank underfloor which gives a theoretical range of nearly 500km at the most efficient cruising speeds.

Interestingly, when you watch the slow-motion runs of the boat in the Test Video (scan the QR code hereby) you can see the newly released SRH (Soft Riding Hull) in action. It has fully welded reverse chines from bow to transom.

“The older Albacores only had pressed chines that went up around half way,” said Donovan, “but these go all the way to the bow and make for a much drier ride.”

Behind the wheel, this was a much quieter hull than I expected it to be. There must be some good flotation and insulation under the self-draining deck, because I was expecting this tinny to sound tinny.

The one concession to any sort of luxury in this rig was the fancy Stessco seats and the padded gunwales.

The console is substantial, and I like Stessco’s new MFD mounting solution that involves a large piece of perspex covering the console opening. Anything that makes flush-mounting easier is a thumbs-up in my book.

And on a personal note, well done Stessco for having a go at making the underfloor storage areas actually dry. I’ve been banging on to aluminium boat manufacturers for years about this disadvantage of aluminium boat design, and they’ve tackled it with a welded lip and drainage channels built in to let the water flow around and away from the edge. Since it wasn’t belting down with rain on the test day, I didn’t get to see exactly how well the concept worked, but rest assured I’d rather my dry clothes and expensive fishing tackle in this hatch than 95% of the other hatches on the market.

Post COVID especially, boats are not as affordable as they used to be, however this boat motor and trailer package from Stessco with the 200hp Yamaha comes in at $90,036. For more information you can visit Stessco’s website on
