View Full Version : New 4 strock for 2005
06-17-2004, 09:54 PM
I spoke to a dealer today who informed me that Polaris is producing a 150hp two cylinder inline engine. He said it was designed by Porshe. It swings about 7K rpm. Torque is not advertised at this time. It is turbo charged and EFI. with all electronics. Electric start and alternator. No weight known at this time. As EPA pushes more 2 cycles out of water sports more 4 strokes will be available. It also has a counter balancer. We may get some new stroke for some old machines and bring down the cost . (feel free to correct spelling)

That's sounds interesting. :)
Sea-doo jet-ski importers here in Oz, are making a big noise about their 220hp supercharged 3-cylinder 4-stroke jet ski. :eek:
Wonder if Polaris might up the ante a bit to outdo Sea-doo later on. One can only hope I suppose.

220 h.p. on a Jet-Ski!!?? I live about a mile from Mission Bay, where it's packed with them. I can imagine how many more are going to crash into each other when they have that many horses.

Here's the link Ken for the Sea-Doo PWC. :D
Oh, an interesting point is. The engine in this PWC is made by Rotax. The Sea-Doo is made by the Bombadier Company (Bombadier/Rotax).
The gyro community may see this engine being used perhaps in the next 3 - 5 years. That's if, and a big IF mind you, of that Rotax continue to produce this engine in large volumes. Let's hope so anyway.
For those who aren't that fussed about PWC's, here's the engine specs.
Supercharged four-stroke, three-cylinder Rotax® SOHC with Intercooler
Bore x Stroke 100mm x 63.4mm
Displacement/hp 1494 cc / 215 hp
Compression ratio 8.5:1
Carburetion / Fuel injection Multi-port fuel injection
Lubrication Dry sump, pressure oil system
Cooling Closed-loop cooling system
Fuel type Regular unleaded

Yes Ken that is what we need to be on the look out for new but crashed ones. So we can get a deal on it and test them with say the new universal gearbox in NZ. autoflight?
Could be a replacement for that 2.2/2.5 and save weight too.

Never thought of that, Brent. I should hang around Mission Bay's boat ramp and offer salvage money for the crashed ones towed ashore.
