Evinrude Etec - V8 450hp

One of those boatshow rumours however from a reliable source.

Can anyone elaborate?

That's a very big jump over anything existing of any make outboard - it'll need a very special saddle and transom to hold it! Could be useful for the Rib rides market I suppose?

I WANT IT NOW!!!

Evinrude's top motor is a 300hp V6 which is 50hp per cylinder - a V8 version would easily make 400hp so quite possible. The problem is Evinrude seem slower off the mark than most - they are prob the last to have introduced a 300hp so God knows when they will get around to it.

And to think there were V8 2 stroke outboards in the 70s and 80s making over 400hp and weighing 225kgs - what happened to progess I wonder???

The main problem with that sort of power will be getting it into the water with a single small screw. A duoprop would be the answer as done once by Yam on a 150hp outboard.

Not so .. have you been on a boat with a Verado 275 or 300 ?.. power transmission is instantaneous in mid range, and quite unbelievable Not having experienced this with other outboards, I'm at a loss to explain the dynamics, but it can be done ... and no it is not just the supercharger .. I've said on other posts, slip is what you expect, but you just dont get that, they seem to just bite , so I'm sure its possible with even more power up top.. convention would say there must be a limit though

Exactly - like 150hp more!!!

Having driven a few Volvo outdrive boats the extra grip of a duoprop over a similar single screw is amazing.

No ...you're not getting me here .. the speed of the boat increases exactly as you increase the Verado revs , there appears to be no slip .. dont ask me how plus.. as they are installed high, only half of the prop is in the water, this is achieved with a standard Laser or Vengeance prop as I had

Has it been confirmed for sure yet or is it still just a rumour?
