Moving from Twins to a Single
Am chasing any advice or anyone that may be experienced in changing a boat from twin outabords over to a single?
I own a 26ft Fury Centre console and starting to think about repowering. Currently have twin 140hp 4stks and weighing up the options below
Twin 150hp (likely Yamaha as they support electric throttle and power steering)
Twin 200hp 4 cyl Yamaha
Twin 200hp 6 cyl Merc
or
Single 300 v8 Merc
The most obvious question is "Have i contacted the manufacturer" Yep I've spoken to Scott many times, and his opinion is both twins and a single will work well.
My problem is, im a creature of habit and i will go back to things that im used to. ie; if i eat a nice meal at a restaraunt, next time i go back to that restaraunt i will likely eat the same meal.
I know the Fury with Twins, i know how it runs, how it balances and how it turns. With a Single 300, i simply do not know what this will be like.
There is another obviuos factor, there is a significant purchase price difference between the Single 300 and any combination of twins, in the vacinity of $10-$15k so that is also weighing in on the decision.
Curious to know if anyone has made the transition on the same boat? and what the expectation compared to actual was like?
The last alternative is putting the Fury up for sale and buying something else....that idea I've been playing with for the last 2 years!
Any info on anyones experience would be greatly appreciated.
Cheers

Lots of pros and cons
I haven't gone down that track but this may be helpful.
The only pro for twins is redundancy, that said a crap tank of fuel and both motors are gone.
Modern motors are pretty good these days, there's more boats out there with one motor on the back versus two and more often than not they're making it home safely.
Less weight on any boat is good, unless you're taking out a pair of 454 magnums and replacing em with something that's a third of the weight. Some boats just like to have a ton of motor and legs hanging off it's bum.
Less weight on your trailer. Allows to carry more fuel without busting your trailers mass weight. Then again saying that it might actually allow you to have more than five litres in your fuel tank without being illegal!.
Twin Yammies = 440 kg v 270kg for the Merc. The saving of 170 kg will be noticeable. Less weight = better fuel burn. Allows for bigger runs on the same amount of juice. If you're worried about weight you can install a strippers pole complete with a pair of strippers and a keg of beer to offset the weight loss.
Less drag one leg in the water v two
Half the maintenance bill = more money for fuel and strippers.
Two batteries instead of four. Less rigging on the back of the boat, steering cables etc, etc it all adds up.
Why stop at 300 hp how about a Merc 450R?
A final pro for twins is the sound factor. When my twin Verados are going full song with the superchargers howling it's a nice way to get the blood running to ones groin!.

Its a vexxed question Bodie,
Its a vexxed question Bodie, highly dependant on where you operate.
I am looking at the same questions for my new boat.
Our time at the islands is often in shit weather with noone else around, and I have gone around the bottom of Wreck Point on a shitty day and thought "what if I had a single and it shit itself now?"
Even 200 meters from the island with the wind blowing the wrong way on a 3 tonne boat is a big problem
Fact is that ANYTHING mechanical, no matter how new, flash or well maintained can fail. I know this as an engineer...
The dirty fuel thing for twins-valid point but you are unlikely to make it 50 miles out to sea anyway and if you don't have a spare set of filters and a water trap fitted you were primed for failure from the beginning.
Your fishing from what I see looks mainly Metro and regional with company-no real reason for twins on that score?

The older you get the more you realize that no one has a f++king clue what they're doing.
Everyone's just winging it.

I do solo runs to fairly remote areas and twice have had to come home on one. Last time it was monties after doing a gearbox.
I've spent a bit of time in a 26 fury with a single 275 verado and although it went well I did think it might of liked a little more weight on the transom in some sea conditions. Haven't been in a twin rig one to compare though.
Does anyone know where the love of god goes, when the waves turn the minutes to hours?

Dunno what these are worth - just an option
Dunno what they cost but would have to be extremely reliable. History is unknown.
Sounds like pushed to be directly suited to a twin replacement with a bit extra weight.

I had a look at one at the
I had a look at one at the Auckland Boat Show last week.
Heard it running, was suprisingly quiet and smooth for a lightweight V8 diesel.
$NZ99K over there.
I'd wait for them to reach critical mass in the marketplace before I contemplated one

Another factor to consiser
Another factor to consiser is the ability to trim a boat with twins (though trims tabs which you may have can alleviate that in any event)

More stability and control
More stability and control with two props in the water in my experience, especially in shitty conditions. Twin 150s although the same HP as a 300 should have heaps more torque for when loaded up.
I spun a prop 20Nm off Coral Bay a few weeks ago and got back unassisted. Sea rescue was an option up there but it's a different story at Abrolhos etc which we frequent.
What do your Suzuki's weigh? What extra weight, if any you'd be adding with those re-power options could be an important factor but Scott woulf be able to guide you there.
If I was going to re-power my f150s I'd go the 200 v6 mercs

Thanks for all the comments
Thanks for all the comments guys
The Dual 140's weigh approx 384kg dry weight. Going to twin Yamaha F200's = 441kg, Twin 200 mercs 432kg, Tiwn 150hp Yamahas 434kg. Merc 150's are lightest 412kg.
So all options weigh more, I have spoken with Fury on the addition of weight and he has always said this boat would perform better with some more weight on the back.
Going the other way (ie; back to a single 300) will drop 100kgs off the back, so no idea how this will perform. Again Fury said shouldn't be an issue.
Stevo, whats your resoning behind going to 200 v6 Mercs? And What boat do you have?

More power, torque & better
More power, torque & better fuel efficiency for no additional weight on the transom.
Ive got a Hydra-Sports 2500vx
