Yellowfin 7400 with twin Suzuki 115hp
  |  First Published: June 2017

It’s fair to say the John Stav from JV Marine loves his Yellowfin boats. In fact, there’s a full range of the hulls in stock in the JV Marine yards. Built in the Telwater factory in Southeast Queensland, the northern boat is eminently suitable for taking on nasty southern seas.

“This is the last boat you’ll buy,” John said as we discussed the rig that he brought down to the ramp at Patterson Lakes for testing.

And being in the business nearly 40 years means that John knows his stuff. As it happens, he also knows every second person at the ramp, and has sold a boat to them at some stage.

At first sight of the Yellowfin, there’s no denying that it’s an impressive rig. Painted gloss black and powered by twin 115hp 4-stroke Suzuki outboards, it sits atop an I-beam Quintrex trailer, manufactured in the same facility as the boat.

Fitted with Telwater’s Catch and Release system, it’s entirely possible to launch and retrieve this boat single-handed – especially in a facility like Launching Way.

Over the years, I haven’t tested that many twin-outboard craft. Each time I do, though, I marvel at how a lightly loaded engine is ridiculously economical. And the figures from the test craft are pretty impressive. The twin Suzukis push along the 7.4m boat – which has a hull dry weight of nearly 1300kg – along at 30km/h with an economy of just under 2km per litre burned. That’s both engines combined. 3000RPM was the best observed cruising speed.

The Yellowfin’s ride is a little different from most boats I’ve tested, too. I expect a hull to get up and ride on its rear chines while cruising. The waterline length of this boat makes it near-impossible and the Quintrex uses nearly all of its 7.3m bow to transom length as a planning surface. Minor weight distribution issues are resolved with tweaks of the trim tabs, and as long as you’re not expecting a 100km/h ride, then you’ll get there economically and in comfort.

Given the 250L underfloor fuel tank, the Yellowfin boasts nearly 500km of range at the economical cruising speed. I assume that this is plenty for most weekend applications, even if they involve trolling for tuna for the entire weekend.

The helm seems to have been built for comfort. The seats attest to that, and we loved the fact that you can flush-mount a 12” display and still have room for all of your other gauges – like trim tabs, anchor winch and lighting controls, as well as the necessary switch panels and digital engine gauges.

JV Marine have fitted this test boat with rod holders and accessories that complement the Port Phillip Bay style of fishing. There’s plenty of rod storage (for when they’re in or out of the water) and lots of practical room to get rigged, baited and to deal with the catch.

As tested, this Yellowfin will set you back just under $130,000 to hitch it up and drive it home. However, packages with fewer bells and whistles come in at less than $100K.
