Hyundai SeasAll repower reaping multiple benefits for owner

by Freddy Foote on 15 Dec 2014 Owners of larger twin-engine powered vessels are taking advantage of reliability and quality with Hyundai SeasAll’s common rail turbo diesel engines in their search for considerably improved economy and excellent performance.

Brett McMullen co-founder and Managing Director of Sydney Harbour Boat Storage recently repowered his Sunrunner 37 with twin Hyundai SeasAll S250’s.

The vessel was previously powered by twin 5.0L 270hp Volvo V8 petrol engines, all fed via a large 620L fuel tank.

'The petrol V8’s were proving to be not very efficient or reliable long term. So when deciding to repower, I had set my mind to converting the boat to run more modern and fuel efficient diesels,' says McMullen.

In replacing his petrol engines with two reliable and economical Hyundai SeasAll engines, McMullen was looking for absolute reliability and no loss of performance.

'What I’ve noticed is that we haven’t lost any performance whatsoever which is really fantastic, considering the new engines have slightly less horsepower than the petrol V8’s did. But for a diesel they are a high revving engine and they have quite a broad torque curve, which has made the boat so much better overall. They don’t really behave like an old smelly diesel, and I’m impressed that there is no lag with the turbo chargers.'

The boat can now achieve 34 knots at 48ltrs per hour per engine – the vessel weighs seven ton.

At a cruise of 19.8knots @ 3,000rpm, it burns 21.2ltrs per hour, per engine, giving the vessel a cruise range of 289 nautical miles.

'It’s all so much quieter now, and overall I’m pretty happy with how it’s transformed the boat’s performance, it’s very smooth and a lot cheaper to run.'

On removing the two petrol engines, McMullen also removed the petrol genset from the boat too and changed over to a new diesel model to ensure absolutely no petrol is used on the boat at all.

In making the choice of installing the twin Hyundai SeasAll S250’s into his craft, McMullen also elected to keep his existing stern legs, this was not only easier, but more cost effective too.

'We elected to keep the current Volvo stern legs, as there was nothing wrong with their condition, and the Hyundai SeasAll engine’s adapted to them very easily. Overall, the two engines were priced very well, especially considering all of the technology they include which made them a very attractive option to consider; especially since the engines themselves include a four year Hyundai SeasAll factory warranty'

Australian, Allpower Marine Business Development Manager Brett Sharp says a Hyundai SeasAll diesel engine provide a very cost effective option for those wishing to repower and ‘modernise’ their vessel.

'Essentially, they are an exceptional value packed engine for users who are looking for not only performance, reliability and economy and provide it in a very cost effective package,' says Sharp.

'We have a large dealer network throughout New Zealand, Australia and the Pacific enabling users to have ready access to parts and service no matter where they are. What’s more, we are able to offer competitive pricing and an attractive warranty term for both recreational and commercial users.'
