    New Weber engines at the World Finals


    I will have new Weber 750 engines configured for the Hydrospace for sale at the Lake Havasu World Finals.

    The engine package includes everything you need except fuel and a battery. This includes the turbo unit, intercooler, ECM, throttle body, etc.. The HAVASU ONLY price is $4000.00 cash, and the price when I return will be $4500.00. The Euro changes daily, so this price is limited to the current inventory. I have a booth at the Finals Thursday - Sunday. Contact me direct at [email protected]

    Thanks,
    Randy

    How does this engine configuration differ from the Polaris MSX 110 and MSX 150?

    What would it take to adapt/install one of these in the MSX?

    Hydrospace

    From Wikipedia, the free encyclopedia

    Jump to: navigation, search
    The Hydrospace is the world's first stand-up four-stroke jet ski, or personal watercraft. It was introduced in October 2005 by Hydrospace Inc. In 2007, Hydrospace Inc. changed their name to HSR-Benelli following the acquisition of Benelli Motori (related to, but unaffiliated with Benelli shotguns or Benelli motorcycles).
    The company originated in Pöchlarn, Austria, with US offices in Pompano Beach, Florida. The Hydrospace is a single-passenger stand-up watercraft which was designed primarily for racing. Until 2008, the only model offered was the "Hydrospace S4", with a retail price of around $15,000 USD.
    The S4 is powered by a two-cylinder water-cooled engine with a displacement of 749cc, which is rated at 110 hp. The engine is equipped with a turbocharger from the factory. The S4 has a dry weight of 370 lbs. making it the second heaviest stand-up ever made, second only to Sea-doo's 3D which had a dry weight of 580 lbs.
    Although touted as being the most advanced stand-up ever manufactured, the S4 has been plagued with problems. The S4 has had numerous recalls on various pieces of faulty equipment. The hulls are also known to be of very lightweight construction and will break under strenuous operating conditions.[citation needed] The control handles are constructed of carbon fiber, which is very brittle and known to break during operation – a serious safety concern. The throttle cable is also known to jam in the wide-open position, causing further safety concerns.
    In 2008, the newly formed HSR-Benelli released new models of personal watercraft, including the first PWC powered by a V6. The Series-R Prestige and the Series-R Race Edition three-person PWCs are both are powered by V6s, rated at 278 and 342 horsepower, respectively.

    Excellent!!!

    I like the definition!!

    The MSX-150 and the S4 configuration share many items, but the biggest difference is the cooling system..The S4 is an "open loop" system that depends upon fresh water for both exhaust & engine cooling. The MSX-110/150 / Polaris snowmobile / Redline revolt / Zodiac & Novurania inflatables use a "closed loop" system that contains a radaitor, etc. The watercraft do depend upon fresh water to cool the exhaust. All the blocks are the same, but various water passages, fasteners, etc are drilled and added at the factory to accomondate that particular application.. Yes.. You can use the S4 engine in a Polaris, but modifications must be made..

    Or perhaps the Polaris installation could be reconfigured to open loop cooling

    Is the S4 engine control system (ECM) the same, or could the Polaris MSX ECU be directly utilized?

    I am pondering the possibility of installing a Weber engine into a Polaris SLX size hull

    With the MSX 150 turbo configuration (135HP stock), and Desperado's ECM flash upgrade to further boost power and peak RPM, it could be a potent combination.

    Lots of power, compact size, and very good fuel consumption

    How much does a fully configured Weber 750cc engine weigh?

    How much does a domestic three cylinder engine weigh, including intake system and exhaust up to the water box?

    Abort Mission!

    The weber engine will not fit into a conventional Polaris hull. The distance from the crankshaft centerline to the bttom of the crankcase is too deep, you would have to make the hull "V" much deeper or raise the entire pump / driveline centerline to match the engine!

    You could convert to MSX style coooling to an "open loop" system also.. The MSX 150 (bosch) system will work on the Hydrospace (Walbro) block configuration. The Walbro is 110 HP, so you would obviosly gain an instant 40 HP with the Bosch configuration.

    Randy
