Cant see them catching on, the weight would be astronomical not to mention the price when compared to inboard diesel's.

Maybe not here but the Seppo's will love them!8-)

[NTMID8]

:LOL:Only the coolest of the seppo's though:LOL:

[Skusto]

the offshore tournament guys over there will want them!

[four_button_arnie]

sounds a little underpowered;D she would have to wieght, what 400-550kg???

[Skusto]

1100 pounds apparrently, gm supercharged v8

[STUIE63]

be interesting to see how much they weigh the yammie 350 is a 5.3 litre and weighs 370kg why would an all alloy small block chev weigh much more

[Fatenhappy]

And there's 2 of these things hangin' off the back of the boat?

[finga]

Stay tuned to a bream tournament near you.

Many off the big yank tank boats have been rated to 1100-1200 hp, like Grady white, Boston Whaler, Contender etc. have a look at their website, many around the 30-35ft range have got 3 dirty great big yam 350's hanging off the back

[TimiBoy]

Lol, that's just AWESOME!

Have a couple hangin' off the back of a Rivvie, think of all the fuel space you'd have left after removing the diesels?

And how much fuel do they use? WHO GIVES A SHIT!!!! %^$& the Greenies!!! WOOOHOOOO!!!!!!!

Cheers,

Tim

[myusernam]

reckon there will be guys putting them on their 21' cyclones up in NQ. should go allright

Say.... instead of banning two stroke motors, how about they ban any outboard over 250Hp.

On decent trip with that 560Hp lump would do more environmental damage than a lifetimes use of small two strokes.

cheers

Wouldn't that depend upon the boat?
This is not going to like some couple of 90hp 2 strokes

What about a lot of the VMR and rescue boats?? They like 300hp Suzuki's on them

[maimai]

Hell yeh, would love to see something like that on the back of my boat. Is it based on the merc Verado?

[tunaticer]

Plenty of room for cast netting prawns in that boat......I think it would sit near vertical in the water though.

[TimiBoy]

It's an alloy GM V8 from memory. Nothing to do with the Verado.

Cheers,

tim

[Skusto]

yeah gm supercharged v8 nothing to do with merc, they are 1000 pounds and well 70k each, only the rich will be able to afford them and run them!

[Chris1984]

woohoo might have to replace the 6hp 1970's 6hp johnson on my tinny. about time to she is getting a bit tired8-)

mercury marine has alot to do with this motor, HP / weight looks good also

HP to weight is well advanced say to the 350hp Yamaha::)

If they can make these huge suckers, then where are the diesel outboards?
