You need to let Simon know about that motor, he likes a hand grenade.
How about Renault and BMW, back in the turbo F1 days, they both built 1.5litre motors that for qualifying produced 1200+ hp, but like the Honda, or perhaps the Skyline motor, don't really have an application in the marine world.
Or how about a Keith Black Chevy Drag motor, 5000hp ish!

The japs certainly like to hot up their road cars, but we're getting way off topic here, for a reliable powerful, and lightweight alternative to the current line of Gasoline pleasure boat engines, what do you see as the number one contender then?

Ive no idea, what engine do yamaha use when building a 300 hp petrol sterndrive? I Know its gonna be american isnt it?
It appears to me that you are viewing the world in black and white. try using shades of grey. . . .
Commercially, Yamaha are not over interested in the marine industry, that is apparent by the fact that they use other manufacturers powerheads in their outboards. If they wanted they could build there own engine for marine use but the returns just simply dont stack up. However through business links and associations they are more then willing to have their logo splashed over someone elses engine earning them a few Yen and some more advertising too.
America is the largest engine manufacturer and as such build high volume for low cost. This is the only reason people around the world use their products cos their cheap and plentiful.
Dont get me wrong, they are nice engines, just lazy and old hat.
It will be interesting to see what engines start being put in boats in the future once the price of oil extinguishes the manufacture of these dinosaurs. Im sure their will come a time when it becomes financially rewarding for someone to manufacture an alternative and become the sole marine supplier.

The same as yours, or was, they no longer market Gas sterndrives.
I wasn't aware that Yamaha didn't make their own OB powerheads!
Also, based on your comment re: commercial worth, if this is so, why don't Yamaha buy in the Bravo and re-badge it, instead of building that fkkn dreadfull hydrodrive?

I think you are being slightly generous. I work it out as closer to 500 revs.

You sound surprised that you, the God of Motorboating wasnt informed by Mr Sakamoto himself.
Most of their current stuff is all their own handywork but in the early days they used other manufacturers powerheads whilst testing the Market.
Like i said before, Yamaha are not really interested in the world marine stage at present, however they do like to supply their products to the home market in Japan.
I openly admit that i dont know anything about the Hydrodrive. But i will look into it now i know about it.
Another small factoid: Did you know that Yamaha Build big boats out of composite and GRP? not just inflatables.
Right, its been emotional but ive got work to do. ive another million to make by teatime.
PS. Tomorrow ill be talking about Selva and their links with Alquaida . . . . ..

I don't really understand your tone! after all, you are the one claiming to be the fountain of 'obvious knowledge' that the out of date world needs to listen to.

There is no tone intended or indeed implied,
And i am certainly not claiming to be the "Fountain of Knowledge" that the out of date world needs to listen to.
However, the world is a stage and i have played my part and it is up to you the audience to listen or not, as you choose.
Makes no difference to me, do i care what people think of me?
No.

OK,
Lets take this project to a new thread and leave this one to fade away.
However, lets all not take this too seriously OK.

In essence I guess the Verado is the type of motor R-Don is talking about, it will be interesting to see how they fare as time goes on.
what's the bigest intended hp gonna be from the Verado? (currently 275 I think)
