Porsche Designed Boat on eBay
I just ran across this auction on eBay. They claim to have a Porsche designed boat with 'modified' 928 engine in it.

I read about that thing back when I was in 5th grade in Automobile magazine when they compared the new 944 turbo S to the 911 turbo. I still have that issue too. Incredible boat.

Actually, after seeing the ledged "Porsche Boat 928 engine" I flashed on the idea of mating a 928 engine to a bored 30 over Jacuzzi jet boat unit and turning my 40,000-gallon pool into one wild a$$ hot tub <img border="0" title="" alt="[Eek!]" src="eek.gif" />
No bikini should be able to withstand that turbulent current <img border="0" alt="[jumper]" title="" src="graemlins/jumper.gif" />
I’d call it the “Porsche-Binford 928-2000 Bikini stripper 20-knot pool special”
Now if I could just find someone who knew how to turbocharger it <img border="0" alt="[ouch]" title="" src="graemlins/c.gif" />

What is different on a marine engine, compared to one for our beloved cars?
The boat was designed by F.A. Porsche - the design company owned by Ferdinand Alexancer ("Butzi") Porsche in Zell am See, Austria.
It's not a Porsche factory design, even though the engieering center in Weissach would probably take on a such project. After all, they have done takns, fork lifts, Airbus-cockpits, Harely engines, KIA suspensions - why not do a boat?
i'm a big fan of F.A. Porsche - wish I could afford their $200 aerodynamic toaster. But that one is just a little over the top, price wise...

Ya but Nicole...Porsche's toaster burns the Porsche emblem directly into the toast <img border="0" alt="[burnout]" title="" src="graemlins/burnout.gif" /> ...remember...it's not about how you get toasted but how do you look after you've been toasted <img border="0" alt="[ouch]" title="" src="graemlins/c.gif" />

There is no radiator like on a car.
Which begs a question.
How do you condition the block and heads for highly corrosive salt water?

Doesn't the Cigarette/ Scarab style boats have horsepower #'s in the thousands? I recall seeing one at a boat show years ago that had twin Chevy 454's in it (they may even have been turbocharged also), I can't see a 928 motor putting out enough power to move a boat like that with any speed.

John,
Which begs a question.

You use a water to water heat exchanger, similar to a car except you use water instead of air. Most boats use them, with antifreeze in the engine block. It's called fresh water cooling. Cheap boats don't, and it is called raw water cooling.

I've seen the boat or a boat exactly like it here in Miami several years ago and it looks really nice, but it is a fairly small boat (~23'). So you can't compare it to the cigarette boat line (35' - 46'). But I am sure it is not overpowered with one 928 engine, even though I recall it was a very light carbon hull. The 38' Top Gun from Cigarette used to come with twin 454's or 502's and supercharging as an option. I participated as a driver (steering only) in my friends 46' tripple 1350hp Cigarette once in a race, since his driver was sick. It was a very scary venture to say the least. Hitting 5' wakes at 105 mp/h is not what I would ever want to do again.
cheers,
Sab.

I think it was first released in the early '80s. Basically, no marine water directly cools the engine.

Some of the main differences with marine engines are:
1) The external components are altered to be "spark safe", meaning items like alternators, starters, and distributors are specially vented to not allow gas fume buildup.
2) Engines that are carburated are jetted very differently, and the overflow is directed back into the center of the carb. (SC engines are another item also)
3) The torque buildup is much lower than your typical auto engine, as you must spin the prop to break free. (In fact if you look real close to the offshore race boats with even high horsepower, there is a aeration tube on the outdrive that allows the prop to spin at low speed. And thats even with the large blade 1000hp units).
** The key here is a change in cam.
4) Cooling is a bit different, but there are some that use internal cooling with a sort of radiator, but its water cooled vs air cooled. Most though are raw water fed into a pump.
5) The stress on the engines is far greater than any land vehicle. Think of it, you are pushing 7-10,000 lbs of weight at 4-5000 rpm for a long duration in a race (and thats the factory class boats, not the SuperX boats). You are looking at an oil change every 25-50hours of use if that says anyting.
6) The engines themselves come from a Marine Division of a company, like GM. All the internals are what you'd see in a HP application vs street.
7) A 400+HP motor, natural aspirated, is gonna be 6-8k minimum. A 800+hp blown motor, is gonna run 70K.
....great part is, its nothing but pure horsepower and a ride like you can't imagine.
(and the noise that goes with it)

X-Post from OT: Looks like somebody found a new use for the 928 motor, in a boat.
