I think they'll say anything to get out of a warranty claim b*****ds,
strange thing is, it does only seem to be the yanmar 300 that does this, I did hear a rumour that there was a harmonic issue between the six cylinder motor and the bravo at that power, after all they take 525hp of supercharged petrol no problem and, my V8's have done a few hours now with loads of abuse/in and out of the water at full chat and all that stuff with no problems and mine aren't even Bravo X drives!

Bravo drive failures

Has any one considered that "driver error" may be part of the equation?

I looked at Konrad and I think the 1000 hp leg your refering to isnt for diesl as the torque is to high on these motors and is desighned for inbord petrols.

Konrad have a leg that can handle a max of 500hp diesl but you got a seperate gearbox and with the weight and engine size you still need a boat to go in, so it is a none starter.In my humble opinion whats the point in havving nearly 2mtrs lopped of the back end of a 9 mtr boat inc engines and box.You will have more room with a 7 mtr outbord version.

You loose to much room out the boat.and your also into dimminishing returns syndrome with bg twin diesls.

Konrad

The other drive system is a Konrad, but this has a Borg Warner type gearbox.

Crazyhorse.

Sometimes I worry about you, do you have an Eye, Brain, Fingers networking problem?

The Konrad does have a seperate gearbox, but they do supply a "stand off box" that the gearbox will fit in, enabling you to have a smaller engine compartment.

And please explain your theory on the Diminishing Returns Syndrome.
