Well maybe they're working of the principle that if you can afford the fuel bill for that engine, you can afford to have it serviced

Unless of course they have just gone for low down grunt for hauling big boats around at lowish speeds.
That is true but only part of the picture, and quite misleading at best

My friend as just got a new Honda diesel he asked why is there only one engine to chouse from
the reply was, only 3% of Honda cars are Diesel and they will not be making another
As the next genaration of engines will all be Bio fuel,
Which is why i think Yamaha are making bigger petrol engine
to replace inboard diesel engine in the future, after all the biggest market in the world for out boards is The USA
i also asked the question in a thread that if the new genaration of two strokes are so good Etec for one.
Why are the big players Yamaha Suzuki Honda etc.
not investing in two strokes.

Honda have never bothered much with diesels - prob because the Yank market used to hate them but they are starting to catch on over there now.

Mercury still make 2 strokes - I would have thought they were a pretty big player.

Finally on bio fuels I think they are the spawn of the devil and hopefully the Greens will eventually realise they do more harm than good. In Mexico for example many poor families are facing starvation as the price of corn has gone up 400% because of it's demand for biofuel. In Indonesia they are ripping up vast amounts of the rainforest to grow coconut palms again for oil Also it is very debatable if these fuels ARE carbon neutral - a lot of energy is used to plant and then harvest and process these crops.

Mercury have not put the investment into two stroke like they have the verrado, and i agree that corn ect will become exspensive and rain forset will be cut, But the bigger picture says that bio fuels will come its only a matter of time.

Only if the enviro mentalists have their way. I honestly think they do more harm than good.

This oil pipe line thing with Russia turning off the supply with Germany is a wake up call its not the Evos that will cause Bio fuels to come in, it will be me and you,
when your freedom of movment is stoped because some one has turned the tap off, i wonder how many people will ask where the EU grain mountain went and why havant we got that Bio fuel that people where talking about years ago.

Bio fuel just can NOT deliver. You need vast areas of land and there just isn't enough to go around. They need to keep oil and gas for cars and generate electricity with nuclear - there would be enough to go around then!!!

They already have cars running on hydrogen gas - normal ic engines NOT fuel cells - it's similar to using LPG. The biggest problem is getting enough hydrogen but with more nuclear reactors it wouldn't be a problem. Nuke powerstations can't just be turned off so the electric is wasted at night - what better use than to make hydrogen to run cars - real carbon neutral and we still have lovely V8s etc!!!

One thing I find hard to understand is how do you get the transom saddle bracket to withstand the forces, many engines break these in offshore racing and they are not 804lbs I think only time will tell
