HPDI or V-MAX?

[joakimhansson]

Whats the difference between these engines?

Evinrude vs Yamaha 2-Stroke, everyone talk about ETEC does anyone have experience on hpdi or v-max here? Good/bad?

200 hp and up!

I've had very good experience with the HPDI 200. And I haven't heard a single bad report from anynone running the 2.6 litre block motors - that's the 150 HPDI and 200 HPDI standard and V-Max. The 3.3 litre block motors are different (250 and 300 HPDI) and there are numerous reports across Europe and the US from owners suffering blown pistons.

Over a long period of running the 200HPDI I've had very good fuel consumption - about 1.1 litres per nautical mile, the very worst being 1.2 litres per nautical mile when most of the time was spent flat out at wide open throttle.

The V-Max engines are only available in long shaft - no XL or XXL, so make sure your transom is suitable. I believe thay come with low water pickup - check http://www.yamaha-motor.co.uk/produc...di_150-250.jsp

Thanks Richard,

Maybe I´m stupid, but both hpdi and v-max have 2,6 liter engines and hpdi(injection).

How fast is your Scorpion with the 200? It looks very nice!

Yes the 150 and 200 HPDI and HPDI V-Max are 2.6 litre. The 250 and 300 HPDI are 3.3 litre, also the 250 HPDI V-Max is 3.3. litre.

We get 44-45kts in most conditions with 2-3 passengers and half fuel load, 48kts one up and light fuel load.

But why should I buy a V-Max not a only a HPDI? with 200 hp. I thought v-max was designed for faster boats.

The drive leg on a Vmax has less drag though the water and a better air intake apprently.

Thank you, Now I can go to bed....V-max is my melody :) And I like the bike Yamaha V-Max too....
