I wonder if this engine will make it into our ski boats?

Volvo Penta IPS revealed


olvo have just rewritten the rules with regard motorboat propulsion systems. In a stroke they may have consigned stern-drives and shaft drives to history, and in the process revolutionised the way motorboats are designed and built.

Inboard Performance System, or IPS, is an innocuous title for the most important development in propulsion since the invention of the outdrive, and something that may render the conventional shaftdrive obsolete.

IPS is a combined engine and propulsion system, sold as a package in the same way that an outdrive can be. You can't buy the propulsion unit on its own, and currently IPS is only approved for twin installation. There are two models, both employing the same propulsion/transmission unit. Combining this unit with the 310hp D6-310 gives the IPS-400, attach the 370hp D6-370 and you have the IPS-500. The engines are the same as used in sterndrive and conventional shaftdrive applications.

Lets start by listing the main benefits compared with conventional shaftdrive, go on to see how those benefits are delivered, and then look at the implications of this system for recreational craft of the future. For implications there certainly are, especially for manufacturers of diesels in the 350hp to 500hp bracket. The longer term depends on whether Volvo intend to develop the concept to accept greater power outputs. And I think we can all guess the answer to that.

Imagine getting a pull from one of those luxury yachts, that would be nuts... thanks for the link

I heard of that in a boat show but I think (for me) that sucks cose where i lived theirs a lot of bad things on water like trees so if u take one bye bye

[kento911]

why?? sb chevy works great, the next evolution in boat motors will be dual overhead cam v8's w/ 4 valves per cylinder, and a variable valve timing system

[Greg T]

yea, what kento911 said. Everyone knows that.
